+The following method is available to interact with the usermod from other code modules:
+- `getIlluminance` read the brightness from the sensor
 
 ## Change Log
+Jul 2022
+- Added Home Assistant Discovery
+- Implemented PinManager to register pins
+- Made pins configurable in usermod menu
+- Added API call to read luminance from other modules
+- Enhanced info-screen outputs
+- Updated `readme.md`

-Hello! I have written a v2 usermod for the BME280/BMP280 sensor based on the [existing v1 usermod](https://github.com/Aircoookie/WLED/blob/master/usermods/Wemos_D1_mini%2BWemos32_mini_shield/usermod_bme280.cpp). It is not just a refactor, there are many changes which I made to fit my use case, and I hope they will fit the use cases of others as well! Most notably, this usermod is *just* for the BME280 and does not control a display like in the v1 usermod designed for the WeMos shield. 
+# Usermod BME280
+This Usermod is designed to read a `BME280` or `BMP280` sensor and output the following:
+- Temperature
+- Humidity (`BME280` only)
+- Pressure
+- Heat Index (`BME280` only)
+- Dew Point (`BME280` only)
 
-- Requires libraries `BME280@~3.0.0` (by [finitespace](https://github.com/finitespace/BME280)) and `Wire`. Please add these under `lib_deps` in your `platform.ini` (or `platform_override.ini`).
-- Data is published over MQTT so make sure you've enabled the MQTT sync interface.
-- This usermod also writes to serial (GPIO1 on ESP8266). Please make sure nothing else listening on the serial TX pin of your board will get confused by log messages!
+Configuration is performed via the Usermod menu.  There are no parameters to set in code!  The following settings can be configured in the Usermod Menu:
+- Temperature Decimals (number of decimal places to output)
+- Humidity Decimals
+- Pressure Decimals
+- Temperature Interval (how many seconds between temperature and humidity measurements)
+- Pressure Interval
+- Publish Always (turn off to only publish changes, on to publish whether or not value changed)
+- Use Celsius (turn off to use Fahrenheit)
+- Home Assistant Discovery (turn on to sent MQTT Discovery entries for Home Assistant)
+- SCL/SDA GPIO Pins
 
-To enable, compile with `USERMOD_BME280` defined (i.e. `platformio_override.ini`)
+Dependencies
+- Libraries
+  - `BME280@~3.0.0` (by [finitespace](https://github.com/finitespace/BME280))
+  - `Wire`
+  - These must be added under `lib_deps` in your `platform.ini` (or `platform_override.ini`).
+- Data is published over MQTT - make sure you've enabled the MQTT sync interface.
+- This usermod also writes to serial (GPIO1 on ESP8266). Please make sure nothing else is listening to the serial TX pin or your board will get confused by log messages!
+
+In addition to outputting via MQTT, you can read the values from the Info Screen on the dashboard page of the device's web interface.
+
+Methods also exist to read the read/calculated values from other WLED modules through code.
+- `getTemperatureC()`
+- `getTemperatureF()`
+- `getHumidity()`
+- `getPressure()`
+- `getDewPointC()`
+- `getDewPointF()`
+- `getHeatIndexC()`
+- `getHeatIndexF()`
+
+# Compiling
+
+To enable, compile with `USERMOD_BME280` defined  (e.g. in `platformio_override.ini`)
 ```ini
+[env:usermod_bme280_d1_mini]
+extends = env:d1_mini
 build_flags =
   ${common.build_flags_esp8266}
   -D USERMOD_BME280
-```
-or define `USERMOD_BME280` in `my_config.h`
-```c++
-#define USERMOD_BME280
+lib_deps = 
+  ${esp8266.lib_deps}
+  BME280@~3.0.0
+  Wire
 ```
 
-Changes include:
-- Adjustable measure intervals
-  - Temperature and pressure have separate intervals due to pressure not frequently changing at any constant altitude
-- Adjustment of number of decimal places in published sensor values
-  - Separate adjustment for temperature, humidity and pressure values
-  - Values are rounded to the specified number of decimal places
-- Pressure measured in units of hPa instead of Pa
-- Calculation of heat index (apparent temperature) and dew point
-  - These, along with humidity measurements, are disabled if the sensor is a BMP280
-- 16x oversampling of sensor during measurement
-- Values are only published if they are different from the previous value
-- Values are published on startup (continually until the MQTT broker acknowledges a successful publication)
 
-Adjustments are made through preprocessor definitions at the start of the class definition.
-
-MQTT topics are as follows:
+# MQTT
+MQTT topics are as follows (`<deviceTopic>` is set in MQTT section of Sync Setup menu):
 Measurement type | MQTT topic
 --- | ---
 Temperature | `<deviceTopic>/temperature`
 Humidity | `<deviceTopic>/humidity`
 Pressure | `<deviceTopic>/pressure`
 Heat index | `<deviceTopic>/heat_index`
-Dew point | `<deviceTopic>/dew_point`
+Dew point | `<deviceTopic>/dew_point`
+
+If you are using Home Assistant, and `Home Assistant Discovery` is turned on, Home Assistant should automatically detect a new device, provided you have the MQTT integration installed.  The device is separate from the main WLED device and will contain sensors for Pressure, Humidity, Temperature, Dew Point and Heat Index.
+

+# Welcome to the battery usermod! 🔋
+
+Enables battery level monitoring of your project.
+
+For this to work, the positive side of the (18650) battery must be connected to pin `A0` of the d1 mini/esp8266 with a 100k Ohm resistor (see [Useful Links](#useful-links)).
+
+If you have an ESP32 board, connect the positive side of the battery to ADC1 (GPIO32 - GPIO39)

+     * addToConfig() will make your settings editable through the Usermod Settings page automatically.
+     *
+     * Usermod Settings Overview:
+     * - Numeric values are treated as floats in the browser.
+     *   - If the numeric value entered into the browser contains a decimal point, it will be parsed as a C float
+     *     before being returned to the Usermod.  The float data type has only 6-7 decimal digits of precision, and
+     *     doubles are not supported, numbers will be rounded to the nearest float value when being parsed.
+     *     The range accepted by the input field is +/- 1.175494351e-38 to +/- 3.402823466e+38.
+     *   - If the numeric value entered into the browser doesn't contain a decimal point, it will be parsed as a
+     *     C int32_t (range: -2147483648 to 2147483647) before being returned to the usermod.
+     *     Overflows or underflows are truncated to the max/min value for an int32_t, and again truncated to the type
+     *     used in the Usermod when reading the value from ArduinoJson.
+     * - Pin values can be treated differently from an integer value by using the key name "pin"
+     *   - "pin" can contain a single or array of integer values
+     *   - On the Usermod Settings page there is simple checking for pin conflicts and warnings for special pins
+     *     - Red color indicates a conflict.  Yellow color indicates a pin with a warning (e.g. an input-only pin)
+     *   - Tip: use int8_t to store the pin value in the Usermod, so a -1 value (pin not set) can be used
+     *
+     * See usermod_v2_auto_save.h for an example that saves Flash space by reusing ArduinoJson key name strings
+     * 
+     * If you need a dedicated settings page with custom layout for your Usermod, that takes a lot more work.  
+     * You will have to add the setting to the HTML, xml.cpp and set.cpp manually.
+     * See the WLED Soundreactive fork (code and wiki) for reference.  https://github.com/atuline/WLED
+     * 
+     * I highly recommend checking out the basics of ArduinoJson serialization and deserialization in order to use custom settings!

 I use the PIR Sensor to automatically turn on the WLED analog clock in my home office room when I am there.
 The LED strip is switched [using a relay](https://github.com/Aircoookie/WLED/wiki/Control-a-relay-with-WLED) to keep the power consumption low when it is switched off.

 The info page in the web interface shows the remaining time of the off timer. Usermod can also be temporarily disbled/enabled from the info page by clicking PIR button.

+Use the potentiometers on the sensor to set the time delay to the minimum and the sensitivity to about half, or slightly above.
 You can also use usermod's off timer instead of sensor's. In such case rotate the potentiometer to its shortest time possible (or use SR602 which lacks such potentiometer).
 
 ## Usermod installation
 
-1. Copy the file `usermod_PIR_sensor_switch.h` to the `wled00` directory.
-2. Register the usermod by adding `#include "usermod_PIR_sensor_switch.h"` in the top and `registerUsermod(new PIRsensorSwitch());` in the bottom of `usermods_list.cpp`.
+**NOTE:** Usermod has been included in master branch of WLED so it can be compiled in directly just by defining `-D USERMOD_PIRSWITCH` and optionaly `-D PIR_SENSOR_PIN=16` to override default pin. You can also change the default off time by adding `-D PIR_SENSOR_OFF_SEC=30`.

 To query or change the PIR sensor state the methods `bool PIRsensorEnabled()` and `void EnablePIRsensor(bool enable)` are available.
 
 When the PIR sensor state changes an MQTT message is broadcasted with topic `wled/deviceMAC/motion` and message `on` or `off`.
-Usermod can also be configured to just send MQTT message and not change WLED state using settings page as well as responding to motion only during nighttime (assuming NTP and lattitude/longitude are set to determine sunrise/sunset times).

+## Control PWM fan speed using JSON API
+
+e.g. you can use `{"PWM-fan":{"speed":30,"lock":true}}` to lock fan speed to 30 percent of maximum. (replace 30 with an arbitrary value between 0 and 100)
+If you include `speed` property you can set fan speed as a percentage (%) of maximum speed.
+If you include `lock` property you can lock (_true_) or unlock (_false_) the fan speed.
+If the fan speed is unlocked, it will revert to temperature controlled speed on the next update cycle. Once fan speed is locked it will remain so until it is unlocked by the next API call.

-These files allow WLED 0.9.1 to report the temp sensor on the Quinled board to MQTT. I use it to report the board temp to Home Assistant via MQTT, so it will send notifications if something happens and the board start to heat up.
-This code uses Aircookie's WLED software. It has a premade file for user modifications. I use it to publish the temperature from the dallas temperature sensor on the Quinled board. The entries for the top of the WLED00 file, initializes the required libraries, and variables for the sensor. The .ino file waits for 60 seconds, and checks to see if the MQTT server is connected (thanks Aircoookie). It then poles the sensor, and published it using the MQTT service already running, using the main topic programmed in the WLED UI.

+# Si7021 to MQTT (with Home Assistant Auto Discovery) usermod
+
+This usermod implements support for [Si7021 I²C temperature and humidity sensors](https://www.silabs.com/documents/public/data-sheets/Si7021-A20.pdf).
+
+As of this writing, the sensor data will *not* be shown on the WLED UI, but it _is_ published via MQTT to WLED's "built-in" MQTT device topic. 
+
+```
+temperature: $mqttDeviceTopic/si7021_temperature
+humidity: $mqttDeviceTopic/si7021_humidity
+```
+
+The following sensors can also be published:
+
+```
+heat_index: $mqttDeviceTopic/si7021_heat_index
+dew_point: $mqttDeviceTopic/si7021_dew_point
+absolute_humidity: $mqttDeviceTopic/si7021_absolute_humidity
+```
+
+Sensor data will be updated/sent every 60 seconds.
+
+This usermod also supports Home Assistant Auto Discovery.
+
+## Settings via Usermod Setup
+

-WLED v2 UserMod for running macros at sunrise and sunset.
-
-At the time of this text, this user mod requires code to be changed to set certain variables:
-    1. To reflect the user's graphical location (latitude/longitude) used for calculating apparent sunrise/sunset
-    2. To specify which macros will be run at sunrise and/or sunset. (defaults to 15 at sunrise and 16 at sunset)
-    3. To optionally provide an offset from sunrise/sunset, in minutes (max of +/- 2 hours), when the macro will be run.
-
-In addition, WLED must be configured to get time from NTP (and the time must be retrieved via NTP.)
-
-Please open the UserMod_SunRiseAndSet.h file for instructions on what needs to be changed, where to copy files, etc.
-
-If this usermod proves useful enough, the code might eventually be updated to allow prompting for the required information
-via the web interface and to store settings in EEPROM instead of hard-coding in the .h file.
-
-This usermod has only been tested on the esp32dev platform, but there's no reason it wouldn't work on other platforms.

- * REQUIREMENTS:
- *      The Dusk2Dawn library must be installed.  This can be found at https://github.com/dmkishi/Dusk2Dawn.  The 1.0.1 version of this library found via
- *      Arduino or platformio library managers is buggy and won't compile.  The latest version from github should be used.
- * 
- *      NTP must be enabled and functional.  It simply makes no sense to have events on sunrise/sunset when an accurate time isn't available.
- * 
- *      The user's geographical latitude and longitude must be configured (in decimal, not degrees/minutes/etc) using m_fLatitude and m_fLongitude
- * 
- *      if desired, an offset of up to +/- 2 hours can be specified for each of sunrise/sunset using m_sunriseOffset and m_sunsetOffset (defaults to 0)
- * 
- *      The specific macro to run at sunrise and/or sunset can be changed using m_sunriseMacro and m_sunsetMacro. (defaults to 15 and 16)
- * 
- *      From the Dusk2Dawn library:
- *          HINT: An easy way to find the longitude and latitude for any location is
- *          to find the spot in Google Maps, right click the place on the map, and
- *          select "What's here?". At the bottom, you’ll see a card with the
- *          coordinates.
- * 
- *      Once configured, copy UserMod_SunRiseAndSet.h to the sketch file (the same folder as wled00.ino exists), 
- *      and then edit "usermods_list.cpp":
- *          Add '#include "UserMod_SunRiseAndSet.h"' in the 'includes' area
- *          Add 'usermods.add(new UserMod_SunRiseAndSet());' in the registerUsermods() area

+# Audioreactive usermod
+
+Enabless controlling LEDs via audio input. Audio source can be a microphone or analog-in (AUX) using an appropriate adapter.
+Supported microphones range from analog (MAX4466, MAX9814, ...) to digital (INMP441, ICS-43434, ...).
+
+Does audio processing and provides data structure that specially written effects can use.
+
+**does not** provide effects or draw anything to an LED strip/matrix.
+
+## Additional Documentation
+This usermod is an evolution of [SR-WLED](https://github.com/atuline/WLED), and a lot of documentation and information can be found in the [SR-WLED wiki](https://github.com/atuline/WLED/wiki):
+* [getting started with audio](https://github.com/atuline/WLED/wiki/First-Time-Setup#sound)
+* [Sound settings](https://github.com/atuline/WLED/wiki/Sound-Settings) - similar to options on the usemod settings page in WLED.
+* [Digital Audio](https://github.com/atuline/WLED/wiki/Digital-Microphone-Hookup)
+* [Analog Audio](https://github.com/atuline/WLED/wiki/Analog-Audio-Input-Options)
+* [UDP Sound sync](https://github.com/atuline/WLED/wiki/UDP-Sound-Sync)
+
+
+## Supported MCUs
+This audioreactive usermod works best on "classic ESP32" (dual core), and on ESP32-S3 which also has dual core and hardware floating point support. 
+
+It will compile succesfully for ESP32-S2 and ESP32-C3, however might not work well, as other WLED functions will become slow. Audio processing requires a lot of computing power, which can be problematic on smaller MCUs like -S2 and -C3. 
+
+Analog audio is only possible on "classic" ESP32, but not on other MCUs like ESP32-S3.
+
+Currently ESP8266 is not supported, due to low speed and small RAM of this chip. 
+There are however plans to create a lightweight audioreactive for the 8266, with reduced features.
+## Installation 
+
+### using customised _arduinoFFT_ library for use with this usermod
+Add `-D USERMOD_AUDIOREACTIVE` to your PlatformIO environment `build_flags`, as well as `https://github.com/blazoncek/arduinoFFT.git` to your `lib_deps`.
+If you are not using PlatformIO (which you should) try adding `#define USERMOD_AUDIOREACTIVE` to *my_config.h* and make sure you have _arduinoFFT_ library downloaded and installed.
+
+Customised _arduinoFFT_ library for use with this usermod can be found at https://github.com/blazoncek/arduinoFFT.git
+
+### using latest (develop) _arduinoFFT_ library
+Alternatively, you can use the latest arduinoFFT development version.
+ArduinoFFT `develop` library is slightly more accurate, and slighly faster than our customised library, however also needs additional 2kB RAM.
+
+* `build_flags` = `-D USERMOD_AUDIOREACTIVE` `-D UM_AUDIOREACTIVE_USE_NEW_FFT`
+* `lib_deps`= `https://github.com/kosme/arduinoFFT#develop @ 1.9.2`
+
+## Configuration
+
+All parameters are runtime configurable. Some may require a hard reset after changing them (I2S microphone or selected GPIOs).
+
+If you want to define default GPIOs during compile time, use the following (default values in parentheses):
+
+- `-D SR_DMTYPE=x` : defines digital microphone type: 0=analog, 1=generic I2S (default), 2=ES7243 I2S, 3=SPH0645 I2S, 4=generic I2S with master clock, 5=PDM I2S
+- `-D AUDIOPIN=x`  : GPIO for analog microphone/AUX-in (36)
+- `-D I2S_SDPIN=x` : GPIO for SD pin on digital microphone (32)
+- `-D I2S_WSPIN=x` : GPIO for WS pin on digital microphone (15)
+- `-D I2S_CKPIN=x` : GPIO for SCK pin on digital microphone (14)
+- `-D MCLK_PIN=x`  : GPIO for master clock pin on digital Line-In boards (-1)
+- `-D ES7243_SDAPIN` : GPIO for I2C SDA pin on ES7243 microphone (-1)
+- `-D ES7243_SCLPIN` : GPIO for I2C SCL pin on ES7243 microphone (-1)
+
+**NOTE** I2S is used for analog audio sampling. Hence, the analog *buttons* (i.e. potentiometers) are disabled when running this usermod with an analog microphone.
+
+### Advanced Compile-Time Options
+You can use the following additional flags in your `build_flags`
+* `-D SR_SQUELCH=x`  : Default "squelch" setting (10)
+* `-D SR_GAIN=x`     : Default "gain" setting (60)
+* `-D I2S_USE_RIGHT_CHANNEL`: Use RIGHT instead of LEFT channel (not recommended unless you strictly need this).
+* `-D I2S_USE_16BIT_SAMPLES`: Use 16bit instead of 32bit for internal sample buffers. Reduces sampling quality, but frees some RAM ressources (not recommended unless you absolutely need this).
+* `-D I2S_GRAB_ADC1_COMPLETELY`: Experimental: continously sample analog ADC microphone. Only effective on ESP32. WARNING this _will_ cause conflicts(lock-up) with any analogRead() call.
+* `-D MIC_LOGGER`     : (debugging) Logs samples from the microphone to serial USB. Use with serial plotter (Arduino IDE)
+* `-D SR_DEBUG`       : (debugging) Additional error diagnostics and debug info on serial USB.
+
+## Release notes
+
+* 2022-06 Ported from [soundreactive WLED](https://github.com/atuline/WLED) - by @blazoncek (AKA Blaz Kristan) and the [SR-WLED team](https://github.com/atuline/WLED/wiki#sound-reactive-wled-fork-team).
+* 2022-11 Updated to align with "[MoonModules/WLED](https://amg.wled.me)" audioreactive usermod - by @softhack007 (AKA Frank Möhle).

-# :battery: Battery status/level Usermod :battery:
-
-This Usermod allows you to monitor the battery level of your battery powered project.
-
-You can see the battery level and voltage in the `info modal`. 
-
-For this to work the positive side of the (18650) battery must be connected to pin `A0` of the d1mini/esp8266 with a 100k ohm resistor (see [Useful Links](#useful-links)).
-
-If you have a esp32 board it is best to connect the positive side of the battery to ADC1 (GPIO32 - GPIO39)

-     * It will be called by WLED when settings are actually saved (for example, LED settings are saved)
-     * If you want to force saving the current state, use serializeConfig() in your loop().
-     * 
-     * CAUTION: serializeConfig() will initiate a filesystem write operation.
-     * It might cause the LEDs to stutter and will cause flash wear if called too often.
-     * Use it sparingly and always in the loop, never in network callbacks!
-     * 
-     * addToConfig() will make your settings editable through the Usermod Settings page automatically.
-     *
-     * Usermod Settings Overview:
-     * - Numeric values are treated as floats in the browser.
-     *   - If the numeric value entered into the browser contains a decimal point, it will be parsed as a C float
-     *     before being returned to the Usermod.  The float data type has only 6-7 decimal digits of precision, and
-     *     doubles are not supported, numbers will be rounded to the nearest float value when being parsed.
-     *     The range accepted by the input field is +/- 1.175494351e-38 to +/- 3.402823466e+38.
-     *   - If the numeric value entered into the browser doesn't contain a decimal point, it will be parsed as a
-     *     C int32_t (range: -2147483648 to 2147483647) before being returned to the usermod.
-     *     Overflows or underflows are truncated to the max/min value for an int32_t, and again truncated to the type
-     *     used in the Usermod when reading the value from ArduinoJson.
-     * - Pin values can be treated differently from an integer value by using the key name "pin"
-     *   - "pin" can contain a single or array of integer values
-     *   - On the Usermod Settings page there is simple checking for pin conflicts and warnings for special pins
-     *     - Red color indicates a conflict.  Yellow color indicates a pin with a warning (e.g. an input-only pin)
-     *   - Tip: use int8_t to store the pin value in the Usermod, so a -1 value (pin not set) can be used
-     *
-     * See usermod_v2_auto_save.h for an example that saves Flash space by reusing ArduinoJson key name strings
-     * 
-     * If you need a dedicated settings page with custom layout for your Usermod, that takes a lot more work.  
-     * You will have to add the setting to the HTML, xml.cpp and set.cpp manually.
-     * See the WLED Soundreactive fork (code and wiki) for reference.  https://github.com/atuline/WLED
-     * 
-     * I highly recommend checking out the basics of ArduinoJson serialization and deserialization in order to use custom settings!

-# Blynk controllable relay
-This usermod allows controlling a relay state from the user variables. It also allows the user variables to be set over Blynk.
-
-Optionally, the servo can have a reset timer to go back to it's default state after an interval. This interval is set through userVar1.
-
-## Instalation
-
-Replace the WLED06_usermod.ino file in Aircoookies WLED folder with the one here.
-
-## Customizations
-
-Update the following parameters in WLED06_usermod.ino to configure the mod's behavior:
-
-```cpp
-//Which pin is the relay connected to
-#define RELAY_PIN 5
-//Which pin state should the relay default to
-#define RELAY_PIN_DEFAULT LOW
-//If >0 The controller returns to RELAY_PIN_DEFAULT after this time in milliseconds
-#define RELAY_PIN_TIMER_DEFAULT 3000
-
-//Blynk virtual pin for controlling relay
-#define BLYNK_USER_VAR0_PIN V9
-//Blynk virtual pin for controlling relay timer
-#define BLYNK_USER_VAR1_PIN V10
-//Number of milliseconds between updating blynk
-#define BLYNK_RELAY_UPDATE_INTERVAL 5000

+# BobLight usermod
+
+This usermod allows displaying BobLight ambilight protocol on WLED device with a limited command set (not a full implementation).
+BobLight protocol uses a TCP connection which guarantees packet delivery at the possible expense of latency delays. It is not very efficient (as it uses plaintext comands) so is not suited for large number of LEDs.
+
+This implementation is intended for TV backlight in combination with XBMC/Kodi BobLight add-on.
+
+The LEDs can be configured in usermod settings page. The configuration is simple: you enter the number of LED pixels on each side of your TV (top, right, bottom, left).
+The LEDs should be wired in a clockwise orientation starting in the middle of bottom side (left half of bottom leds is where the string should start).

+
+## Installation 
+
+Add `-D USERMOD_BOBLIGHT` to your PlatformIO environment.
+If you are not using PlatformIO (which you should) try adding `#define USERMOD_BOBLIGHT` to *my_config.h*.
+
+## Configuration
+
+All parameters are runtime configurable though changing port may require reboot.
+
+If you want to define default port during compile time use the following (default values in parentheses):
+
+- `BOB_PORT=x` : defines default TCP port for usermod to listen on (19333)

+This usermod-v2 modification allows the connection of multiple relays, each with individual delay and on/off mode.
+Usermod supports PCF8574 I2C port expander to reduce GPIO use.
+PCF8574 supports 8 outputs and each output corresponds to a relay in WLED (relay 0 = port 0, etc). I you are using more than 8 relays with multiple PCF8574 make sure their addresses are set conscutively (e.g. 0x20 and 0x21). You can set address of first expander in settings.

+# PWM outputs
+
+v2 Usermod to add generic PWM outputs to WLED. Usermode could be used to control servo motors, LED brightness or any other device controlled by PWM signal.
+
+## Installation
+
+Add the compile-time option `-D USERMOD_PWM_OUTPUTS` to your `platformio.ini` (or `platformio_override.ini`). By default upt to 3 PWM outputs could be configured, to increase that limit add build argument `-D USERMOD_PWM_OUTPUT_PINS=10` (replace 10 by desired amount).
+
+Currently only ESP32 is supported.
+
+## Configuration
+
+By default PWM outputs are disabled, navigate to Usermods settings and configure desired PWM pins and frequencies.
+
+## Usage
+
+If PWM output is configured, it starts to publish its duty cycle value (0-1) both to state JSON and to info JSON (visible in UI info panel). To set PWM duty cycle, use JSON api (over HTTP or over Serial)
+
+```json
+{
+    "pwm": {
+        "0": {"duty": 0.1},
+        "1": {"duty": 0.2},
+        ...
+    }
+}
