I have set up several Sonoffs using the Tasmota firmware and they are all working OK. They are the basic sonoff and I am using the GPIO14 input connection to control them locally using a single pole single throw switch (SPST) ie I can toggle the switch and that will turn the sonoff ON or OFF accordingly depending on it’s previous state. This is achieved using GPIO14 set to 09 Switch1. All good.
I now have another sonoff I want to install but the switch I need to use is a momentary switch only - when you press it closes the contacts when you release the contacts open. I had hoped this could be used on the GPIO14 connection and use one of the other available Switch settings but none work. The only one it works on is the same 09 Switch1. Of course what happens is that the sonoff operates when the button is pressed but then immediately reverts state when the button is released…more or less what I would expect however not what I want!
Does anyone know whether the Tasmota firmware supports a momentary action switch or am I doing something else wrong??
Yes I have seen that video and understand I could just parallel up with the onboard button. As Jonathan says though you are theoretically running the risk of resetting the device if someone just presses in the button for more than a few seconds.
It seems strange that the Tasmota firmware covers so many permutations but not this basic one. I will post over there to see if Theo has a response.
