+
+### 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
+

+    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)
+```

+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

+  return true  # Return true if handled
+end
+```
+
+### Web Server Extensions
+
+```berry
+import webserver
+
+# In driver's web_add_handler() method

+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

+```
+
+### 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

+- 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;

+        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

+
+### 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.

+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).
