Configuration as relay with overpower and overtemperature protection

When integration with home assistant exists, it will appear as a switch, 4 sensors (power, temperature, wifi strenght and total daily energy) When the max_power is exceeded, the relay will be switched off and a persistent notification will be created in home-assistant When the max_temp is exceeded, the relay will be switched off and a persistent notification will be created in home-assistant Thanks to Tasmota and Tijmen from this topic Config tested by gieljnssns
