My current garage door setup uses an ESP8266 with a couple of 2 channel relay boards. It is a bit messy and flaky, so I quite like the idea of moving everything to a single 4Ch pro.
I have 2 doors - they require separate pulses for up and down, so the 4 channel relay will be fine. I would also like to integrate into a cover - I currently do this with the 8288 using some simple reed switches connected to 2 spare GPIOs.
I am trying to figure out if there are any spare sensor pins on the 4Ch Pro to allow 2 reed switches to monitor door status? I would like to use ESPHome if possible (all my other Sonoff devices use this). I have read that Rx and Tx are available if logging is disabled, but there is also a suggestion that if Tx is high on boot then the 4ch pro fails to boot? This would mean that if the door was close on booting, it would never boot.
Anyone done anything similar? Does it work?
