# Introduction



OpenBK7231T/OpenBeken is a Tasmota/Esphome replacement for new Tuya modules featuring MQTT and Home Assistant compatibility.

This repository is named "OpenBK7231T_App", but now it's a multiplatform app, supporting build for multiple separate chips:

# Features



OpenBeken features:

- Tasmota-like setup, configuration and experience on all supported platforms (supports [common Tasmota JSON over http](https://www.youtube.com/watch?v=OhdkEJ-SuTU) and MQTT, etc)

- OTA firmware upgrade system (for BK, W*00, BL602, LN); to use OTA, [drag and drop](https://www.youtube.com/watch?v=OPcppowaxaA) proper OTA file on OTA field on new Web App Javascript Console

- Online [builds for all platforms](https://github.com/openshwprojects/OpenBK7231T_App/releases) via Github, configurable [per-user build system](https://www.elektroda.com/rtvforum/topic4033833.html), also supports [Docker builds](https://github.com/openshwprojects/OpenBK7231T_App/tree/main/docker)

- MQTT compatibility with Home Assistant (with both Yaml generator and [HA Discovery](https://youtu.be/pkcspey25V4)) 

- Support for multiple relays, buttons, leds, inputs and PWMs, everything fully scriptable

- [Driver system](https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/drivers.md) for custom peripherals, including [TuyaMCU](https://www.elektroda.com/rtvforum/topic4038151.html) (see [Dimmer tutorial](https://www.elektroda.com/rtvforum/topic3898502.html)), I2C bus and [BL0942](https://www.elektroda.com/rtvforum/topic3887748.html), BL0937 power metering chips, Motor Driver Bridge.

- Hardware and software I2C, supports multiple I2C devices, like TC74 temperature sensor, MCP23017 port expander, PCF8574T LCD 2x16 (or other?), etc

- Hardware and software SPI, support for SPI BL0942, etc

- NTP time from network (can be used with [TH06](https://www.elektroda.com/rtvforum/topic3942730.html) and other TuyaMCU devices), can run any script on selected weekday hour:minute:second

- Dedicated [TuyaMCU support](https://www.elektroda.com/rtvforum/topic4038151.html) with extra TuyaMCU analyzer tool for decoding new devices ([tutorial here](https://www.elektroda.com/rtvforum/topic3970199.html), code [repository here](https://github.com/openshwprojects/TuyaMCUAnalyzer))

- support for [TuyaMCU Battery Powered devices protocol](https://www.elektroda.com/rtvforum/topic3914412.html) (TuyaMCU enables WiFi module only to report the state, eg. for door sensors, water sensors)

- [RGBCW LED lighting control](https://www.youtube.com/watch?v=YQdR7r6lXRY) compatible with Home Assistant (including PWM LEDs, and SM2135, BP5758, [SM15155](https://www.elektroda.com/rtvforum/topic4060227.html) etc )

- LittleFS integration for scripts and large files (you can [write scripts there](https://www.youtube.com/watch?v=kXi8S12tmC8), you can host a page there with [REST interface control](https://www.elektroda.com/rtvforum/topic3971355.html) of device)

- Command line system for starting and configuring drivers, for controlling channels, etc

- Short startup command (up to 512 characters) storage in flash config, so you can easily init your drivers (eg. BL0942) without LittleFS

- Advanced scripting and events system (allows you to mirror Tasmota rules, for example catch button click, double click, hold)

- Easily configurable via commands (see [tutorial](https://www.elektroda.com/rtvforum/topic3947241.html))

- Thanks to keeping Tasmota standard, OBK has basic compatibility with [ioBroker](https://www.youtube.com/watch?v=x4p3JHXbK1E&ab_channel=Elektrodacom) and similar systems through TELE/STAT/CMND MQTT packets, Tasmota Control app is also supported

- Advanced and custom drivers like [synchronized PWM groups with configurable dead time](https://www.elektroda.com/rtvforum/topic4025665.html)

- WS2812B support, see [scripting tutorial](https://www.elektroda.com/rtvforum/topic4036716.html)

- LFS and REST API allows you to create and host a custom HTML+CSS+JS page on device with a custom GUI/display of channels/TuyaMCU dpIDs, see [tutorial](https://www.elektroda.com/rtvforum/topic3971355.html) and see [sample page](https://www.elektroda.com/rtvforum/viewtopic.php?p=20932186#20932186) , and see [final version of custom TOMPD-63-WIFI page](https://www.elektroda.com/rtvforum/topic4040354.html)
