Here's some info about the GHome SW5 smart light switch with an LN882H-based Shenzhen Cuco module. I do not have this device but user @jumpingcoconutmonkey kindly donated the Tuya factory firmware for analysis after posting on Reddit.
The SW5 can be seen in previous posts with a similar module but based on Beken BK7231T: https://www.elektroda.com/rtvforum/topic3892160.html
and with BK7231N: https://www.elektroda.com/rtvforum/topic4030814.html
firmware boot log at 921600 baud:
But perhaps the most interesting bit is that this is the first LN882H firmware we have that offers an OTA upgrade
The Tuya dev API Explorer gives us this info with device paired
showing the OTA bin is to be downloaded from https://images.tuyaeu.com/smart/firmware/upgr...ay1605149472695Vxa2/1742027683b313abb8468.bin
