Generic AU Tuya 16A Smart Plug with Belling BL0937 + CB2S - Boot log, pics, OpenBeken template

Here's a rather generic 16A Tuya Australian wifi smart plug, with Belling BL0937 power metering chip, which I will take apart and flash with OpenBeken. Available from Ali Express Kayesmart Life Store

A thin spudger was used to pry open case. Hardly any effort needed with this one, the glue seemed pretty weak all the way round



Unlike most of the UK/EU plugs this one has all three pins soldered to the PCB. 63/37 pb solder was added to each top solder point to lower the melting point. Without this there's a risk the plastic surrounding the prongs will warp/melt.



CB2S removed and soldered for backup/flashing


First, boot log @115200 baud from TX2 on the back of CB2S





v1.1.23 firmware - known patched - no Cloudcutter option

It looks like a good candidate for testing our "RF only" powersave feature, I just need to either manually edit the pull request to support desired syntax:

or ask contributor to normalize it...
