Is there any way that you can trigger a toggle with an ESP32 on a Sonoff mini?
My idea is that the ESP32 will be sitting next to the Sonoff and have a few sensors on it, and should be able to controll the Sonoff mini.
I know I can set the state in Home Assistant but I’m looking for a hardware solution so that I’m not relying on any network at all.
The Sonoff mini already use the S1 and S2 for human interface, now I need a ESP32 interface.
The switch connected to S1 and S2 is a two state switch (not NO/NC) only on/off so I can’t build a 2-way or 3-way switch.
Anyone that knows about the hardware side of Sonoff switches?
As I understand it GPIO0 is the one that toggles the relay and has a button connected to it.
This button is closed to ground to toggle (?).
So what if I solder a wire from ESP32 to GPIO0 of the Sonoff?
Wouldn’t that toggle the Sonoff?
No. Not a tested working solution. But I have heard from a good source that my idea should work.
I don’t have all the parts yet (to the complete thing), so I’m still waiting to start the testing.
