Any recommendation for a value-for-money wall mounted switch panel (e.g. say 4 switches, could be powered from 240V) that has push button with a LED that integrate with Home Assistant (wifi/homekit). The requirement would be:
a) Ability to control the LED indicator on a particular switch (within the panel of say 4 switches) to show whether there are any downstairs lights on or not,
b) Pushing the particular push button switch itself would either (a) turn all lights off downstairs if there is at least one of them on, or (b) turn them all on [if none are on].
I was going to use the “SHELLY PLUS I4” with a 4-gang clipsal switch with LEDs, but then I’m realizing I won’t be able to correctly set the LEDs on the switches to match my requirements above I don’t think.
