I have a Shelly 1 connected to a fan heater.
It is in AC power mode and switching the load without issue. The load has a momentary switch with low voltage logic; one press for on and then press again for off. I am using the relay and a pulse to deal with this.
Of course, the problem is I do not know the true state of the heater; all I know is that I’ve pulsed the momentary switch.
I don’t need the SW input on the Shelly directly and I wonder how I can decouple it from the really and simply use it as a sensor. If it detects 240v the heater is on, if it doesn’t the heater is off. I am feeding that from the heater element directly.
I’m not sure if I need any logic on the Shelly as I can deal with that in HA. I just need to read that state as 0 or 1…
I’ve tried all the firmwares and failed, probably through incompetence. I can read the state of SW GPIO but it doesn’t seem to reflect reality…it’s either always stuck at 0 or 1 (inverted pin or not…)
Can anyone please confirm if this is possible?
Thanks!
