This device uses a Tasmota incompatible module which needs to be replaced with an ESP. Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill.

You have to replace the existing MWA6S with a (previously programmed) ESP-02S or ESP8685-WROOM-03.

You need a size 2.0 triangle bit to open the case. The screws are under rubber stoppers, a fine screwdriver or needle pulls them out. In addition, the underside is clipped in.

Successfully opened you can remove the circuit board with the MWA6S on a breakout board.

The MWA6S is held in place with a drop of glue: remove, then desolder the part.

Solder in the ESP-02S and fix it again with glue.
