Might be a simple question but several searches and no luck?
I have a Sonoff basic with the latest Tasmota.
I use the main relay to control a coffee machine. I have attached a led illuminated external switch on GPIO 14 in switchmode 9 (toggle) and are illuminating the switch with PMW power from GPIO 3 in PMW1 mode (37)
The main relay is called Power1 and the light in the switch is called Power2.
How can I control the brightness in the button to be at 30 % during the dark hours, 60 % during the bright hours and 100% when the Power1 relay is in “ON” mode?
I can adjust the brightness of the LED in the button by a slider in the Tasmota web-interface but I would like it to be controlled by action in MQTT.
Some info of the setup:

How do I go about telling the system that the Power2 is a light with brightness adjustability?
I have tried a few “lights” configurations, but no luck so far?
