I am testing 2 Sonoff basic switches for stability in daily use.
If i find them safe to use then i want to use one for the opening and closing of my driveway gate.
To switch the gate i simply need to make a contact like a push-button.
in the userconfig.h i sett a value APP_PULSETIME 10.
And i modified the Sonoff to make an independent connection by removing a few connections to the relay and pin-out, and ad another connection.
I use another one in the same way, but this is for the reset button on a heater.
They are both on a different wifi access point.
I controll them with MQTT and it all seems to work great.
There is only one glitch.
If i look in the history of Hass.io then i notice that both Sonoffs so now and then switch randomly.
Once in a few days. I cant find what is causing this.
At first i thought it happened on reconnecting to a wifi network but that seems not the case.
I hope someone can point me in a direction where to look further.
I use the same switches and firmware and they are very stable. However I am not using them as push buttons. Are you sure the physical switches are actually switching randomly ? Perhaps HA is just not reporting the state correctly ? Perhaps there is an issue with firmware APP_PULSETIME command? Valid PULSETIME values are from 112 - 64900. You are using 10 ?
The switches actually switch. It has been a few days now and they did not act weird.
Sometimes they are good for a week and then suddenly one switch moment occurs.
I do use a pulsetime 10 for 10 miliseconds.
I read somewhere this should work.
I think this is a WIFI issue with Tasmota/Sonoff. The device will restart if it loses WIFI and changes relay states. There are settings to prevent this but mine are set correctly. I had this happen to me yesterday. Here is some info.
Where/how can I change this wificonfig? Looked around on the Tasmota github but can’t really find it.
Also looked around on the browser page of my flashed sonoff. Can’t find it there either.
