It seems that after some minutes the device has reset itself! Settings were lost and it entered AP mode. Any tips?

Work shelly 1 with espurna?
Or tasmota Firmware?

[abmantis]

By the way, I used IwIP v2 and a flash size of 2M (1M SPIFFS). Could that (specially IwIP) be the cause for the device reseting itself?

You don't need SPIFFS for ESPurna. Simply use the 1M layout size. Current stable version still uses SDK 2.3.0, not 2.4.X, you might want to test with that.

[abmantis]

But there should be no issue in using a 2M layout with 1M SPIFFS, right?
I'll try 2.3.0 then. What is the best way to debug this kind of behaviour?

[xoseperez]

The best way when there is a reset is to debug it wired. I would use the 12V input and connect RX, TX and GND from the debug port to your computer, open a serial monitor and play with it.

Hi Guys! Where can I get the finished .bin for Shelly1?

Thank you

how is it going to work with Shelly2?

[xoseperez]

I have just pushed support for the Shelly2 in the dev branch.

@xoseperez Good news! What about the power meter? It has a power monitoring IC MCP39F501 (https://www.microchip.com/wwwproducts/en/MCP39F501)

[xoseperez]

The schematic for the Shelly2 is not available, is it?

@xoseperez the power meter is working with Tasmota : https://github.com/arendst/Sonoff-Tasmota/wiki/Shelly-1-and-2
Code is here : https://github.com/arendst/Sonoff-Tasmota/blob/development/sonoff/xnrg_04_mcp39f501.ino
Apparently the MCP39F501 use the ESP Serial port.
