[BK7231N/YX-B3S] Tuya Smart WIFI Power Strip RH-M601 6AC + 3USB

Tuya Smart WiFi Power Strip RH-M601 w/power monitoring

No actual pictures of the inside yet (will add soon) but it is very simple to pull apart despite the triangle head screws. Once the back is off there are two main boards. The B3S module is on the first board with the USB sockets. This power strip uses a different module than I've seen anywhere else, the YX-B3S-VER01.

Pinout of the module:


Because the BL0942 chip is connected to TXD/RXD of the BK7231N, the module has to be removed from the board before it can be programmed. It might be possible to to temporarily cut the traces to the BL0942 so the whole module doesn't have to be removed. When I
take photos of the inside I will check that possibility.

Use these commands to start power monitoring in Autoexec.bat
