I’ve flashed a Shelly 1 Gen3 to Esphome but was assuming it was a 1PM which I ordered. Only noticed afterwards it’s in fact just the Shelly 1 gen3 (Shelly 1 Gen3) and not a PM.
Does anyone have a pinout for this? Seems like it’s loaded the esp32c3 firmware and I have temp monitoring but nothing else is showing up.
What you mean with pinout? The add-on header?
Gpio 5 is relay and 10 is switch if I remember well.
You didn’t post your code…
I have found that relay is GPIO5 on this model, but the switch is NOT GPIO10 and the button is NOT GPIO1.
I also do NOT have a bl0942 on GPIO6/7. So much of this looks outwardly like the Shelly 1PM Gen3 but is wired totally different.
Here is the code, I have assumed that like the 1PM Gen3 there is a current and voltage sensor, but I’m not sure. I am also experimenting with an override to prevent the switch turning off the output.

You assumed wrong, what would make the difference then??
Try gpio4 for the button.
ok, removed the power monitor code. Any idea which GPIO is used for the switch terminal input?
Was gpio4 correct for button?
Sorry, GPIO4 is correct for the button (inverted) and the switch is correct but I was assuming it would detect AC live or DC + whereas in DC mode it needs to be pulled to ground. All working now, thanks for your help. Should I submit a page for the wiki?
You are welcome.
Up to you.
Important that we know the pins have not been swapped over time.
Led 0
Button 4
Relay 5
Switch 10
Temp sensor 3
All present except the LED, this model doesn’t seem to have an LED visible on the chassis and I can’t see anything shining through the plastic case when creating the light on GPIO0.
Simple gpio switch on 0, doesn’t give any sign of life?
I don’t remember the location, but for Shelly Plus 1 it’s near add-on header, so you see it through the “holes”.
And it’s inverted if I remember well.
I added the LED like I saw for the other Shelly devices but after enabling the entity and toggling the LED in HA I see no visible light on the device.
Only had a brief look, but based on what you wrote it seems to be the same config as the 1L Shelly 1L | ESPHome Devices
I don’t know what you saw for other…
No signs of life, unless the LED is really well hidden. I tried to open the case but can get the clips undone without breaking something.
Similar but appears to be ESP32 Vs ESP8266 and without the 2nd switch.
