# Berry for Tasmota
This document covers Tasmota-specific Berry features and extensions, complementing the general Berry language reference.
## Introduction
Berry is the next generation scripting language for Tasmota, embedded by default in all ESP32 based firmwares (NOT supported on ESP8266). It is used for advanced scripting, superseding Rules, and enables building drivers, automations, and UI extensions.
## Tasmota-Specific Modules
Beyond standard Berry modules, Tasmota provides additional modules:
| Module | Description | Import |
|--------|-------------|--------|
| `tasmota` | Core integration module | Automatically imported |
| `light` | Light control | Automatically imported |
| `mqtt` | MQTT operations | `import mqtt` |
| `webserver` | Web server extensions | `import webserver` |
| `gpio` | GPIO control | `import gpio` |
| `persist` | Data persistence | `import persist` |
| `path` | File system operations | `import path` |
| `energy` | Energy monitoring | Automatically imported |
| `display` | Display driver integration | `import display` |

```berry
# GPIO constants (gpio module)
gpio.INPUT, gpio.OUTPUT, gpio.PULLUP, gpio.PULLDOWN
gpio.HIGH, gpio.LOW
gpio.REL1, gpio.KEY1, gpio.LED1, gpio.I2C_SCL, gpio.I2C_SDA
# ... many more GPIO function constants

tasmota.compile("file.be") # Compiles .be to .bec
```
**Autostart**: Place `autoexec.be` in filesystem to run Berry code at boot.
### Tasmota Integration Functions
#### Core Tasmota Functions

tasmota.set_timer(delay_ms, function)
tasmota.remove_timer(id)
tasmota.defer(function) # Run in next millisecond
# Cron scheduling
tasmota.add_cron("*/15 * * * * *", function, "id")
tasmota.remove_cron("id")
tasmota.next_cron("id") # Next execution timestamp
# Time functions

```
#### Device Control
```berry
# Relays and Power
tasmota.get_power() # Array of relay states
tasmota.set_power(idx, state) # Set relay state
# Lights (use light module)
light.get() # Current light status
light.set({"power": true, "bri": 128, "hue": 120})
# Light attributes: power, bri (0-255), hue (0-360), sat (0-255),
# ct (153-500), rgb (hex string), channels (array)
```
#### Custom Commands
```berry
# Add custom Tasmota commands
def my_command(cmd, idx, payload, payload_json)
# cmd: command name, idx: command index
# payload: raw string, payload_json: parsed JSON
tasmota.resp_cmnd_done()
end
tasmota.add_cmd("MyCmd", my_command)
tasmota.remove_cmd("MyCmd")
```
### Tasmota Drivers
Create complete Tasmota drivers by implementing event methods:
```berry
class MyDriver
def every_second() # Called every second
end
def every_50ms() # Called every 50ms
end
def web_sensor() # Add to web UI
tasmota.web_send("{s}Sensor{m}Value{e}")
end
def json_append() # Add to JSON teleperiod
tasmota.response_append(',"MySensor":{"Value":123}')
end
def web_add_main_button() # Add button to main page
import webserver
webserver.content_send("<button onclick='la(\"&myaction=1\");'>My Button</button>")
end
def button_pressed() # Handle button press
end
def mqtt_data(topic, idx, data, databytes) # Handle MQTT
end
def save_before_restart() # Before restart
end
end
# Register driver
driver = MyDriver()
tasmota.add_driver(driver)
```
### Fast Loop
For near real-time events (200Hz, 5ms intervals):
```berry
def fast_function()
# High-frequency processing
end
tasmota.add_fast_loop(fast_function)
tasmota.remove_fast_loop(fast_function)
```
### GPIO Control
```berry
import gpio
# GPIO detection and control
gpio.pin_used(gpio.REL1) # Check if GPIO is used
gpio.pin(gpio.REL1) # Get physical GPIO number
gpio.digital_write(pin, gpio.HIGH) # Set GPIO state
gpio.digital_read(pin) # Read GPIO state
gpio.pin_mode(pin, gpio.OUTPUT) # Set GPIO mode
# PWM control
gpio.set_pwm(pin, duty, phase) # Set PWM value
gpio.set_pwm_freq(pin, freq) # Set PWM frequency
# DAC (ESP32 GPIO 25-26, ESP32-S2 GPIO 17-18)
gpio.dac_voltage(pin, voltage_mv) # Set DAC voltage
# Counters
gpio.counter_read(counter) # Read counter value
gpio.counter_set(counter, value) # Set counter value
```
### I²C Communication
```berry
# Use wire1 or wire2 for I²C buses
wire1.scan() # Scan for devices
wire1.detect(addr) # Check if device present
wire1.read(addr, reg, size) # Read from device
wire1.write(addr, reg, val, size) # Write to device
wire1.read_bytes(addr, reg, size) # Read as bytes
wire1.write_bytes(addr, reg, bytes) # Write bytes
# Find device on any bus
wire = tasmota.wire_scan(addr, i2c_index)
```
### MQTT Integration
```berry
import mqtt
# MQTT operations
mqtt.publish(topic, payload, retain)
mqtt.subscribe(topic, function) # Subscribe with callback
mqtt.unsubscribe(topic)
mqtt.connected() # Check connection status
# Callback function signature
def mqtt_callback(topic, idx, payload_s, payload_b)
# topic: full topic, payload_s: string, payload_b: bytes
return true # Return true if handled
end
```
### Web Server Extensions
```berry
import webserver
# In driver's web_add_handler() method
webserver.on("/my_page", def()
webserver.content_send("<html>My Page</html>")
end)
# Request handling
webserver.has_arg("param") # Check parameter exists
webserver.arg("param") # Get parameter value
webserver.arg_size() # Number of parameters
# Response functions
webserver.content_send(html) # Send HTML content
webserver.content_button() # Standard button
webserver.html_escape(str) # Escape HTML
```
### Persistence
```berry
import persist
# Automatic persistence to _persist.json
persist.my_value = 123
persist.save() # Force save to flash
persist.has("key") # Check if key exists
persist.remove("key") # Remove key
persist.find("key", default) # Get with default
```
### Network Clients
#### HTTP/HTTPS Client
```berry
cl = webclient()
cl.begin("https://example.com/api")
cl.set_auth("user", "pass")
cl.add_header("Content-Type", "application/json")
result = cl.GET() # or POST(payload)
if result == 200
response = cl.get_string()
# or cl.write_file("filename") for binary
end
cl.close()
```
#### TCP Client
```berry
tcp = tcpclient()
tcp.connect("192.168.1.100", 80)
tcp.write("GET / HTTP/1.0\r\n\r\n")
response = tcp.read()
tcp.close()
```
#### UDP Communication
```berry
u = udp()
u.begin("", 2000) # Listen on port 2000
u.send("192.168.1.10", 2000, bytes("Hello"))
# Receive (polling)
packet = u.read() # Returns bytes or nil
if packet
print("From:", u.remote_ip, u.remote_port)
end
```
### Serial Communication
```berry
ser = serial(rx_gpio, tx_gpio, baud, serial.SERIAL_8N1)
ser.write(bytes("Hello")) # Send data
data = ser.read() # Read available data
ser.available() # Check bytes available
ser.flush() # Flush buffers
ser.close() # Close port
```
### Cryptography
```berry
import crypto
# AES encryption
aes = crypto.AES_GCM(key_32_bytes, iv_12_bytes)
encrypted = aes.encrypt(plaintext)
tag = aes.tag()
# Hashing
crypto.SHA256().update(data).finish() # SHA256 hash
crypto.MD5().update(data).finish() # MD5 hash
# HMAC
crypto.HMAC_SHA256(key).update(data).finish()
```
### File System Operations
```berry
import path
path.exists("filename") # Check file exists
path.listdir("/") # List directory
path.remove("filename") # Delete file
path.mkdir("dirname") # Create directory
path.last_modified("file") # File timestamp
```
### Regular Expressions
```berry
import re
# Pattern matching
matches = re.search("a.*?b(z+)", "aaaabbbzzz") # Returns matches array
all_matches = re.searchall('<([a-zA-Z]+)>', html) # All matches
parts = re.split('/', "path/to/file") # Split string
# Compiled patterns (faster for reuse)
pattern = re.compilebytes("\\d+")
matches = re.search(pattern, "abc123def")
```
### Energy Monitoring
```berry
# Read energy values
energy.voltage # Main phase voltage
energy.current # Main phase current
energy.active_power # Active power (W)
energy.total # Total energy (kWh)
# Multi-phase access
energy.voltage_phases[0] # Phase 0 voltage
energy.current_phases[1] # Phase 1 current
# Berry energy driver (with OPTION_A 9 GPIO)
if energy.driver_enabled()
energy.voltage = 240
energy.current = 1.5
energy.active_power = 360 # This drives energy calculation
end
```
### Display Integration
```berry
import display
# Initialize display driver
display.start(display_ini_string)
display.started() # Check if initialized
display.dimmer(50) # Set brightness 0-100
display.driver_name() # Get driver name
# Touch screen updates
display.touch_update(touches, x, y, gesture)
```
### Advanced Features
#### ULP (Ultra Low Power) Coprocessor
```berry
import ULP
ULP.wake_period(0, 500000) # Configure wake timer
ULP.load(bytecode) # Load ULP program
ULP.run() # Execute ULP program
ULP.set_mem(addr, value) # Set RTC memory
ULP.get_mem(addr) # Get RTC memory
```
#### mDNS Support
```berry
import mdns
mdns.start("hostname") # Start mDNS
mdns.add_service("_http", "_tcp", 80, {"path": "/"})
mdns.stop() # Stop mDNS
```
### Error Handling Patterns
Many Tasmota functions return `nil` for errors rather than raising exceptions:
```berry
# Check return values
data = json.load(json_string)
if data == nil
print("Invalid JSON")
end
# Wire operations
result = wire1.read(addr, reg, 1)
if result == nil
print("I2C read failed")
end
```
### Best Practices for Tasmota
1. **Memory Management**: Use `tasmota.gc()` to monitor memory usage
2. **Non-blocking**: Use timers instead of `delay()` for long waits
3. **Error Handling**: Always check return values for `nil`
4. **Persistence**: Use `persist` module for settings that survive reboots
5. **Performance**: Use fast_loop sparingly, prefer regular driver events
6. **Debugging**: Enable `#define USE_BERRY_DEBUG` for development
## Common Tasmota Berry Patterns
### Simple Sensor Driver
```berry
class MySensor
var wire, addr
def init()
self.addr = 0x48
self.wire = tasmota.wire_scan(self.addr, 99) # I2C index 99
if self.wire
print("MySensor found on bus", self.wire.bus)
end
end
def every_second()
if !self.wire return end
var temp = self.wire.read(self.addr, 0x00, 2) # Read temperature
self.temperature = temp / 256.0 # Convert to Celsius
end
def web_sensor()
if !self.wire return end
import string
var msg = string.format("{s}MySensor Temp{m}%.1f °C{e}", self.temperature)
tasmota.web_send_decimal(msg)
end
def json_append()
if !self.wire return end
import string
var msg = string.format(',"MySensor":{"Temperature":%.1f}', self.temperature)
tasmota.response_append(msg)
end
end
sensor = MySensor()
tasmota.add_driver(sensor)
```
### Custom Command with JSON Response
```berry
def my_status_cmd(cmd, idx, payload, payload_json)
import string
var response = {
"Uptime": tasmota.millis(),
"FreeHeap": tasmota.get_free_heap(),
"WiFi": tasmota.wifi("rssi")
}
tasmota.resp_cmnd(json.dump(response))
end
tasmota.add_cmd("MyStatus", my_status_cmd)
```
### MQTT Automation
```berry
import mqtt
def handle_sensor_data(topic, idx, payload_s, payload_b)
var data = json.load(payload_s)
if data && data.find("temperature")
var temp = data["temperature"]
if temp > 25
tasmota.cmd("Power1 ON") # Turn on fan
elif temp < 20
tasmota.cmd("Power1 OFF") # Turn off fan
end
end
return true
end
mqtt.subscribe("sensors/+/temperature", handle_sensor_data)
```
### Web UI Button with Action
```berry
class WebButton
def web_add_main_button()
import webserver
webserver.content_send("<p><button onclick='la(\"&toggle_led=1\");'>Toggle LED</button></p>")
end
def web_sensor()
import webserver
if webserver.has_arg("toggle_led")
# Toggle GPIO2 (built-in LED on many ESP32 boards)
var pin = 2
var current = gpio.digital_read(pin)
gpio.digital_write(pin, !current)
print("LED toggled to", !current)
end
end
end
button = WebButton()
tasmota.add_driver(button)
```
### Scheduled Task with Persistence
```berry
import persist
class ScheduledTask
def init()
if !persist.has("task_count")
persist.task_count = 0
end
# Run every 5 minutes
tasmota.add_cron("0 */5 * * * *", /-> self.run_task(), "my_task")
end
def run_task()
persist.task_count += 1
print("Task executed", persist.task_count, "times")
# Do something useful
var sensors = tasmota.read_sensors()
print("Current sensors:", sensors)
persist.save() # Save counter to flash
end
end
task = ScheduledTask()
```
### HTTP API Client
```berry
class WeatherAPI
var api_key, city
def init(key, city_name)
self.api_key = key
self.city = city_name
tasmota.add_cron("0 0 * * * *", /-> self.fetch_weather(), "weather")
end
def fetch_weather()
var cl = webclient()
var url = f"http://api.openweathermap.org/data/2.5/weather?q={self.city}&appid={self.api_key}"
cl.begin(url)
var result = cl.GET()
if result == 200
var response = cl.get_string()
var data = json.load(response)
if data
var temp = data["main"]["temp"] - 273.15 # Kelvin to Celsius
print(f"Weather in {self.city}: {temp:.1f}°C")
# Store in global for other scripts to use
import global
global.weather_temp = temp
end
end
cl.close()
end
end
# weather = WeatherAPI("your_api_key", "London")
```
### Rule-based Automation
```berry
# Advanced rule that combines multiple conditions
tasmota.add_rule(["ANALOG#A0>500", "Switch1#State=1"],
def(values, triggers)
print("Both conditions met:")
print("ADC value:", values[0])
print("Switch state:", values[1])
tasmota.cmd("Power2 ON") # Activate something
end
)
# Time-based rule
tasmota.add_rule("Time#Minute=30",
def()
if tasmota.rtc()["hour"] == 18 # 6:30 PM
tasmota.cmd("Dimmer 20") # Dim lights for evening
end
end
)
```
## Best Practices and Tips
1. **Always check for nil returns** from Tasmota functions
2. **Use timers instead of delay()** to avoid blocking Tasmota
3. **Implement proper error handling** in I²C and network operations
4. **Use persist module** for settings that should survive reboots
5. **Test memory usage** with `tasmota.gc()` during development
6. **Use fast_loop sparingly** - it runs 200 times per second
7. **Prefer driver events** over polling when possible
8. **Use f-strings** for readable string formatting
9. **Import modules only when needed** to save memory
10. **Use `tasmota.wire_scan()`** instead of manual I²C bus detection

## How Tasmota Works
### Core Architecture
Tasmota is a modular firmware that transforms ESP8266/ESP8285 and ESP32 microcontrollers into intelligent IoT devices. The architecture follows these key principles:
#### 1. Event-Driven System
- Main loop processes events and callbacks
- Non-blocking operations to maintain responsiveness
- Callback system for sensors, drivers, and features
- Timer-based scheduling for periodic tasks
#### 2. Modular Design
- Core functionality always present (WiFi, MQTT, web interface)
- Optional features compiled conditionally using `#define` directives
- Plugin architecture for sensors and peripherals
- Template system for device configuration
#### 3. Communication Hub
- **MQTT**: Primary communication protocol for automation systems
- **HTTP**: Web interface and REST API
- **Serial**: Direct console access for debugging and configuration
- **WebSocket**: Real-time web interface updates

### Command System
All Tasmota functionality is accessible through a unified command system:
- Commands can be sent via MQTT, HTTP, serial, or web console
- Format: `Command [parameter]`
- Response format: JSON for structured data
- Backlog support for multiple commands: `Backlog cmd1; cmd2; cmd3`
### GPIO Management
Tasmota uses a flexible GPIO assignment system:
1. **Templates**: Pre-defined GPIO configurations for specific devices
2. **Components**: Logical functions assigned to physical pins
3. **Modules**: Base hardware configurations
4. **Runtime Configuration**: GPIO can be reassigned without recompilation
## Development Environment Setup
### Prerequisites
1. **PlatformIO**: Primary build system
2. **Git**: Version control
3. **Python**: For build scripts and tools
4. **Serial Programmer**: For initial flashing
### Build Configuration
Create `platformio_tasmota_cenv.ini` for custom environments:
```ini
[env:tasmota32-custom]
extends = env:tasmota32
build_flags = ${env:tasmota32.build_flags}
-DUSE_MY_CUSTOM_FEATURE
```
### User Configuration
Create `tasmota/user_config_override.h`:
```c
#ifndef _USER_CONFIG_OVERRIDE_H_
#define _USER_CONFIG_OVERRIDE_H_
// Enable custom features
#define USE_CUSTOM_SENSOR
#define USE_BERRY_DEBUG
// Disable unused features to save space
#undef USE_DOMOTICZ
#undef USE_KNX
#endif
```
## Driver Development
### Sensor Driver Structure
All sensor drivers follow a standardized pattern:
```c
#ifdef USE_MY_SENSOR
#define XSNS_XX XX // Unique sensor ID
bool MySensorDetected = false;
void MySensorInit(void) {
// Initialize sensor
if (sensor_detected) {
MySensorDetected = true;
}
}
void MySensorEverySecond(void) {
// Read sensor data
}
void MySensorShow(bool json) {
if (json) {
ResponseAppend_P(PSTR(",\"MySensor\":{\"Temperature\":%d}"), temperature);
}
#ifdef USE_WEBSERVER
else {
WSContentSend_PD(HTTP_SNS_TEMP, "MySensor", temperature);
}
#endif
}
bool Xsns_XX(byte function) {
bool result = false;
if (i2c_flg) { // Only for I2C sensors
switch (function) {
case FUNC_INIT:
MySensorInit();
break;
case FUNC_EVERY_SECOND:
MySensorEverySecond();
break;
case FUNC_JSON_APPEND:
MySensorShow(1);
break;
#ifdef USE_WEBSERVER
case FUNC_WEB_SENSOR:
MySensorShow(0);
break;
#endif
}
}
return result;
}
#endif // USE_MY_SENSOR
```

### I2C Development
```c
// I2C Helper Functions
bool I2cValidRead8(uint8_t *data, uint8_t addr, uint8_t reg);
bool I2cValidRead16(uint16_t *data, uint8_t addr, uint8_t reg);
uint8_t I2cRead8(uint8_t addr, uint8_t reg);
uint16_t I2cRead16(uint8_t addr, uint8_t reg);
bool I2cWrite8(uint8_t addr, uint8_t reg, uint8_t val);
// Device Detection Pattern
void MySensorDetect(void) {
if (MySensorDetected) return;
for (uint8_t i = 0; i < SENSOR_MAX_ADDR; i++) {
uint8_t addr = SENSOR_BASE_ADDR + i;
if (I2cValidRead8(&sensor_id, addr, SENSOR_ID_REG)) {
if (sensor_id == EXPECTED_ID) {
MySensorDetected = true;
AddLog(LOG_LEVEL_INFO, PSTR("MySensor found at 0x%02X"), addr);
break;
}
}
}
}
```
## Scripting and Automation
### Rules System
Rules provide event-driven automation:
```
Rule1 ON Switch1#State DO Power1 %value% ENDON
ON Time#Minute=30 DO Publish stat/topic/alert {"time":"30min"} ENDON
```
### Berry Scripting (ESP32)
Berry is a modern scripting language for advanced automation:
```berry
# Simple sensor reading
import json
def read_sensor()
var temp = tasmota.read_sensors()
if temp.contains("Temperature")
print("Current temperature:", temp["Temperature"])
end
end
# Set up timer
tasmota.set_timer(5000, read_sensor)
# Web interface extension
def web_add_button()
webserver.content_send("<button onclick='la(\"&m_toggle=1\");'>Toggle</button>")
end
tasmota.add_driver(web_add_button)
```
### Command Extensions
Add custom commands through Berry or C++:
```berry
def my_command(cmd, idx, payload)
if cmd == "MYCMD"
print("Custom command received:", payload)
tasmota.resp_cmnd_done()
end
end
tasmota.add_cmd('MYCMD', my_command)
```
## Complete Settings Structure Reference
### Settings Memory Layout
Tasmota uses a structured settings system stored in flash memory. The main settings structure is defined in `settings.h`:
```c
typedef struct {
unsigned long cfg_holder; // 000 v6.0.0a
unsigned long save_flag; // 004
unsigned long version; // 008
unsigned short flag; // 00C
unsigned short save_data; // 00E
int8_t timezone; // 010
char ota_url[101]; // 011
char mqtt_prefix[3][11]; // 076
char serial_delimiter; // 09D
uint8_t seriallog_level; // 09E
uint8_t sta_config; // 09F
char sta_ssid[2][33]; // 0A0
char sta_pwd[2][65]; // 102
char hostname[33]; // 183
char syslog_host[33]; // 1A4
uint16_t syslog_port; // 1C5
uint8_t syslog_level; // 1C7
uint8_t webserver; // 1C8
uint8_t weblog_level; // 1C9

char mqtt_grptopic[33]; // 2FE
uint8_t display_model; // 31F
uint8_t display_mode; // 320
uint8_t display_refresh; // 321
uint8_t display_rows; // 322
uint8_t display_cols[2]; // 323
uint8_t display_address[8]; // 325
uint8_t display_dimmer; // 32D
uint8_t display_size; // 32E
uint16_t pwm_frequency; // 32F
power_t power; // 331
uint16_t pwm_value[MAX_PWMS]; // 335
int16_t altitude; // 345
uint16_t tele_period; // 347
uint8_t ledstate; // 349
uint8_t param[PARAM_MAX]; // 34A
int16_t toffset[2]; // 35A
uint8_t display_font; // 35E
} Settings;
### ESP8266 Constraints
- **Flash**: 1MB total, ~500KB available for firmware
- **RAM**: 80KB total, ~25-30KB available for application
- **Stack**: 4KB maximum
### Optimization Techniques
1. **Use PROGMEM for constants**:
```c
const char MyString[] PROGMEM = "Constant string";
```
2. **Minimize dynamic allocation**:
```c
// Avoid
String result = String(value1) + "," + String(value2);
// Prefer
char result[32];
snprintf(result, sizeof(result), "%d,%d", value1, value2);
```
3. **Use flash-efficient data types**:
```c
// Use uint32_t instead of uint8_t for local variables
// Use uint8_t only in structs to save memory
```
## Communication Protocols
### Command Context Structure
All command handlers receive context through the global XdrvMailbox structure:
```c
struct XDRVMAILBOX {
bool grpflg; // Group flag
bool usridx; // User index flag
uint16_t command_code; // Command code
uint32_t index; // Command index
uint32_t data_len; // Parameter length
int32_t payload; // Numeric parameter
char *topic; // MQTT topic
char *data; // Command parameters
char *command; // Command name
} XdrvMailbox;
```
**Key Fields:**
- `command`: The command name (e.g., "Power", "Status")
- `data`: Raw parameter string
- `payload`: Numeric value of first parameter
- `data_len`: Length of parameter string
- `index`: Command index for numbered commands (Power1, Power2, etc.)
### MQTT Integration
```c
// Publish sensor data
void PublishSensorData(void) {
Response_P(PSTR("{\"MySensor\":{\"Value\":%d}}"), sensor_value);
MqttPublishTeleSensor();
}
// Subscribe to commands
bool MyCommand(void) {
if (XdrvMailbox.data_len > 0) {
// Process command
ResponseCmndDone();
return true;
}
ResponseCmndNumber(current_value);
return true;
}
```
### Web Interface Extensions
```c
#ifdef USE_WEBSERVER
void MySensorWebShow(void) {
WSContentSend_PD(PSTR(
"{s}MySensor Temperature{m}%d°C{e}"
"{s}MySensor Humidity{m}%d%%{e}"),
temperature, humidity);
}
#endif
```
## Advanced Features
### Template System
Templates define device GPIO configurations:
```json
{
"NAME":"Custom Device",
"GPIO":[416,0,418,0,417,2720,0,0,2624,32,2656,224,0,0],
"FLAG":0,
"BASE":45
}
```
### Matter Protocol Support
For ESP32 devices, Matter provides standardized IoT communication:
```c
// Matter endpoint configuration
matter.add_endpoint(1, 0x0100); // On/Off Light
matter.add_endpoint(2, 0x0106); // Light with dimming
```
### Display Integration
Universal Display Driver supports 50+ display types:
```
DisplayModel 1 # Select display type
DisplayMode 1 # Text mode
DisplayText [s1l1]Hello World
```
## Testing and Debugging
### Debug Options
Enable debugging in `user_config_override.h`:
```c
#define DEBUG_TASMOTA_CORE
#define DEBUG_TASMOTA_DRIVER
#define USE_DEBUG_DRIVER
```
### Serial Debugging
```c
AddLog(LOG_LEVEL_INFO, PSTR("Debug: value=%d"), value);
AddLog(LOG_LEVEL_DEBUG, PSTR("Detailed info: %s"), info_string);
```
### Memory Monitoring
```c
// Check free heap
uint32_t free_heap = ESP.getFreeHeap();
AddLog(LOG_LEVEL_DEBUG, PSTR("Free heap: %d"), free_heap);
```
## Best Practices
### Code Organization
1. **Use consistent naming**: `MySensor` prefix for all functions
2. **Follow callback patterns**: Implement standard driver callbacks
3. **Handle errors gracefully**: Check return values and sensor presence
4. **Document thoroughly**: Include usage examples and pin assignments
### Performance Considerations
1. **Minimize blocking operations**: Use state machines for long operations
2. **Cache sensor readings**: Don't read sensors more often than necessary
3. **Use appropriate data types**: Consider memory usage vs. precision
4. **Optimize for common cases**: Fast path for normal operations
### Security Guidelines
1. **Validate all inputs**: Check command parameters and sensor data
2. **Use secure defaults**: Enable security features by default
3. **Minimize attack surface**: Disable unused network services
4. **Regular updates**: Keep firmware and dependencies current
## Integration Examples
### Home Assistant Discovery
```c
void PublishDiscovery(void) {
Response_P(PSTR("{"
"\"name\":\"%s MySensor\","
"\"stat_t\":\"%s\","
"\"unit_of_meas\":\"°C\","
"\"dev_cla\":\"temperature\""
"}"), SettingsText(SET_DEVICENAME), GetStateTopic());
MqttPublish(GetDiscoveryTopic("sensor", "temperature"), true);
}
```
### Custom Web Interface
```c
const char HTTP_MYSENSOR[] PROGMEM =
"{s}MySensor{m}"
"<input type='range' min='0' max='100' value='%d' "
"onchange='la(\"&mysensor_val=\"+this.value);'>"
"{e}";
void MySensorWebShow(void) {
WSContentSend_PD(HTTP_MYSENSOR, current_value);
}
```
This guide provides the foundation for understanding and extending Tasmota. The modular architecture, standardized APIs, and extensive documentation make it an excellent platform for IoT development, whether you're adding simple sensor support or implementing complex automation systems.

### I2C Device Detection Pattern
```c
void MySensorDetect(void) {
if (MySensorDetected) return;
for (uint32_t i = 0; i < SENSOR_MAX_ADDR; i++) {
uint8_t addr = SENSOR_BASE_ADDR + i;
if (I2cActive(addr)) continue; // Address already in use
if (I2cValidRead8(&sensor_id, addr, SENSOR_ID_REG)) {
if (sensor_id == EXPECTED_SENSOR_ID) {
I2cSetActiveFound(addr, "MySensor");
MySensorDetected = true;
MySensorAddress = addr;
AddLog(LOG_LEVEL_INFO, PSTR("MySensor found at address 0x%02X"), addr);
break;
}
}
}
}

# OpenTherm Arduino/ESP8266 Library
# OpenTherm Arduino/ESP8266/ESP32 Library
This library provides implementation of OpenTherm protocol.
OpenTherm Library is based on OpenTherm protocol specification v2.2 and works with all OpenTherm compatible boilers. Library can be easily installed into Arduino IDE and compiled for Arduino, ESP8266 and other similar controllers.
OpenTherm Library is based on OpenTherm protocol specification v2.2 and works with all OpenTherm compatible boilers. Library can be easily installed into Arduino IDE and compiled for Arduino, ESP8266/ESP32 and other similar controllers.
OpenTherm protocol requires simple low voltage twowire connection to boiler, but voltage levels (7..15V) still much higher than Arduino/ESP8266 levels, which requires [OpenTherm Adapter](http://ihormelnyk.com/opentherm_adapter).
