Gosund UP111 BL0937 config

Configuration
1

Hey everyone, I’ve tried everything so I’m reaching out to see if anybody can help.

I have a set of Gosund UP111 which have the Realtek AmebaZ2 (RTL8720CF) chipsets.

I’ve managed to get the LED and relay working, however the plug has a BL0937 power monitoring IC, and I cannot for the life of me get that working. I have used a multimeter and traced back the sel_pin to pin 4, the cf_pin to pin 18 and cf1_pin to pin 17, created my config, flashed the device, however it always shows 0 volts and 0 amps.

Does anybody have experience with either this micro-controller or the BL0937 who could tell me if I’m doing something silly?

Hi, did you have any luck with this? I’ve some Eightree ET31 Energy Monitoring Smart Plugs with both the RTL8720CF and BL0937 monitoring chips. I want to move them from Tuya to something else, ideally either Tasmota or OpenBeken ideally as I’ve managed to flash that to other devices I have. Even if you didn’t get anything on the Energy Monitoring, any chance you could let me know what firmware you used and how you flashed them and I’ll have a go myself.
Thanks, Matt
