Successfully got XH-WB3S (BK7238) with driver AHT2X and AHT30 sensor up and running. Then I wanted to try some power saving, with this startup: backlog startDriver SSDP; startdriver AHT2x 7 8 1 2; PowerSave 1 That didn't go well. The BK7238 is not online anymore. How to recover? Connect to UART...

backlog startDriver SSDP; startdriver AHT2x 7 8 1 2; PowerSave 1

That didn't go well. The BK7238 is not online anymore.
How to recover? Connect to UART and reflash? Any simpler method?

Here's another BK7252U cam but this time its beating heart is the 48 pin BK7252UQN48. The usual claims of HD 1080P, night vision, Xiaomi, are seen on the Ali page from which it was bought My journey for this travels the same path as with these other two BK7252U devices, so I'll skip the waffle and go straight to posting some pics, logs and firmware backup, [line:4c5e9746bb] A9_B V2.7_240426 [line:4c5e9746bb]...[Read more]

Hey there! First time posting something over here -- let alone adding a new device. The device is a Prosto WFU-08PM Smartplug with Energy Monitoring. I wasn't able to open it up but because it's glued down. Although I did manage to use Tuya Cloudcutter. It was using MCU 1.3.5 and is based on the BK7231T chip. After messing around in the config panel, it turned out the smartplug uses the BL0937 chip...[Read more]
