Shelly GAS support

[ramponis]

I bought new Allterco device called Shelly GAS
Model: WS2CG

Opening the case...

The SOC is covered but the QR report the MAC address prefix 50:02:91 is registered to Espressif Inc.
So, it is an ESP and port it Tasmota will be good!

Making it work with Tasmota would likely be up to the communication with that STM chip (between QR code and gas sensor), which to me looks like the main MCU running the device, and if the Espressif chip is doing more than acting as a "Wifi modem". The "usual" question again becomes who's going to analyze the device, and work out the details.

OTOH, with Shelly devices usually having pretty good MQTT support, they tend to be ok for "cloudless" operation already.
