SmartLife 2CH wall switch (LYASI) not flashing - Firmware 1.0.7 MCU 1.0.7

[mzanetti]

Trying to flash a LYASI/SmartLife 2CH switch.

It takes the WiFi credentials and connects to the flasher's WiFi, however, doesn't proceed with contacting the webserver.

Firmware Version 1.0.7, MCU version 1.0.7 too.

The device's MAC address is a4:cf:12:a3:5f:a8

From other issues I read that there is a newer version upcoming which is said to work with firmware 2.0 (or also 1.0.5 for some devices?). Could this be related to the same and there is a high chance it'll start working soon or would you recommend to blow off the dust from the soldering iron?

Also, if you think any other logs would be helpful, I'd be happy to provide those.

It seems likely that you have the new firmware (version number is irrelevant as its per product). See if the device is broadcasting anything on UDP port 6666 or 6667 ie, by running nc -u -l -k -p 6667.

We are working on this but no guarantees when or if we will be able to release a workaround.

[mzanetti]

Hmm... actually I cannot seem to catch anything from the device on those ports...

For people ending up here, this might be of interest while the new Firmware can't be OTA'd still: https://www.hackster.io/michael_zanetti/smartlife-tuya-wifi-light-switch-with-tasmota-and-nymea-09a7a6

Please take look at Tuya-VT, it provides the virtually tasmota features on tuya devices using tuyapi. Virtual Tasmota for Tuya Api Devices.

Happy to share that support for HTTPS firmware is in the works #279
