I currently have an ESP 32 connected to a relay that controls my bedroom lights. It has voice control via aREST & IFTTT and also an on/off switch that is triggered by a touch input. It works great but has its limits. I work in a field that has nothing to do with electronics or computers and have only been messing with things like this for a few months so my experience with code/micro-controllers is sub-amateur at very best.

With some help I wrote a program that ties the voice and touch inputs together so if the relay is turned on with one input it can be turned off with the other. The voice and touch both display 1's and 0's for on/off high/low respectively . The issue I have is that when the touch switch is on (1) and the voice control is off (0) I can't tell the voice control to turn off the relay because it is already reading off, so I have to tell it to turn on the relay which triggers a state change and turns the relay off (the code may offer a better description than I can give). I was hoping I could just read every time aREST sent a new off request so I could use the off even if it was already set to off. Maybe a different server type could help me? Like i said I am a total noob so any help or advice is appreciated. I don't fully know the electrical nomenclature so if that wasn't very clear let me know and Ill try and re-phrase.

Never mind, I fixed the problem by running a new output from IFTTT to a separate input so I could set it to strictly off. If anyone is interested the code is as follows. I made it a bit simpler than the original, hopefully it is as reliable.
