Flashing Shelly Ogemray relay 25A

ESPHome

Did anybody have a successful attempt at flashing this “Shelly powered” device? It has the same Shelly ESP32 chip.

It was released around February 2025 but i don’t see anybody talk about it here.

And does anybody have an idea how difficult would this be? Could I just reuse some existing Shelly device ESPHome template and change it a little, or would it be a lot of work?

But I did read somewhere that this device is based off of Gen2 Shelly firmware.

Very likely it’s just Shelly xxx with bigger relay or contactor.
But why you need to flash it in the first place?

To talk over ESP-NOW with other ESP32 devices.

Ok.
Image on shelly forum shows Esp32-C3. So Shelly 1 PM Gen3 could be starting point. Teardown images or schematics would give you correct pinout.
Make shelly forum account and see what they have here…

Or simply open the device if you already have it and trace the circuit.
