[BK7231N/YX-B3S] Tuya Smart WIFI Power Strip RH-M601 6AC + 3USB
Tuya Smart WiFi Power Strip RH-M601 w/power monitoring
Here is my Teardown for this power strip. Not many smart power strips with 6AC channels and this one even has spacing for wall-wart power supplies. Plus it has power monitoring! A bargain at $40 and compatible with OpenBeken.
Specifications:
* Input voltage: AC:125V
* Rated current:15A
* Rated power:1875w
* BL0942 Power Monitoring
* Fast charge: QC 2.0
* Wi-Fi: 2.4GHz IEEE802.11 b/g/n
* Product size(Long* wide* high):228*90*30mm
* LEDs: blue light in button
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

Thank you, that's a very interesting device. I am looking forward seeing the photos of the inside. I haven't seen BS3 module before. Would you be able to provide full pinout for that? Regarding BL0942... [Read more]
You may be right actually. I didn't have full success until I switched out the USB programmer I was using. So removal may not be required. I don't think I'll be able to get the full pinout now that... [Read more]
Some tracks can be figured out with just a photo, we know the BK7231 QFN pinout: https://obrazki.elektroda.pl/9137363100_1684510718_thumb.jpg https://obrazki.elektroda.pl/6366133600_16739445... [Read more]

This board seems to be well build. There are no closeup photos, but I can see even an interference filter at the circuit input. Added after 11 [hours] 55 [minutes]: I just realized something. Isn't... [Read more]
Yes probably. I'm still having crashing issues with SendPost. Any ideas on how to debug it? It'll crash after sending ~10 of the commands. [Read more]
