Basic Configuration As Relay

When integration with home assistant exists, it will appear as 2 Relays with icons and 2 switches (including power, current and sensors) Use cases for this configuration: Roller / Shutter automation and device swichting and monitoring

Thanks to "Anaro" from home assistant forum topic config tested by "Datux"

Configuration as relay with overpower and overtemperature protection

When integration with home assistant exists, it will appear as 2 relays with icons and 2 binary sensors (including power, current and sensors) When the max_power is exceeded on 1 channel, that channel will be switched off and a persistent notification will be created in home-assistant When the max_temp is exceeded, the 2 channels are switched off and a persistent notification will be created in home-assistant Thanks to Datux modified and tested by gieljnssns
