This project is made to run in the Sonoff (smart_timer) and Sonoff POW (smart_timer_pow) hardware.
By default it starts an AP with the name SmartTimer-CHIP_ID and the password is password. Going to http://192.168.4.1 you will see the web configuration portal for WiFi and MQTT.
By pressing the button (GPIO0) for 2 seconds it toggles between normal operation mode and configuration mode.
In the normal operation mode it subscrives to the topic config.mqtt_topic + "/control" and publishes the updated state to config.mqtt_topic + "/status".
The power readings are updated every kPwrUpdFreq seconds (default 20) to the tipoc config.mqtt_topic + "/power" in a JSON format.
The software is based on gmag11/FSBrowser for the web configuration portal and KmanOz/Sonoff-HomeAssistant to get the power readings of the Sonoff POW.
