Arlec PC191HA Series 3 Plug-in Socket: Teardown, Firmware, and Configuration Details

It appears we now have another revision to the Arlec PC191HA Plug-in socket with energy metering. For reference here are the links to the teardown for Series 1 and Series 2.

Some pictures of the outside:


Pictures of the inside:


It appears like a slightly more compact layout with dabs of silicone around the components I assume to improve robustness.

The Tuya firmware version I saw when connecting it to the SmartLife app was 1.1.17 which apparently is a patched version preventing CloudCutter from flashing. I tried one of the profiles with no success.

So I de-soldered the module for flashing the old fashioned way.


Device configuration, as extracted from Tuya (using Easy UART Flasher):
- BL0937 SEL on P24
- Button (channel 1) on P11
- LED (channel 1) on P26
- BL0937 VI on P6
- WiFi LED on P10
- BL0937 ELE on P7
- Relay (channel 1) on P8
Device seems to be using CB2S module, which is using BK7231N.
And the Tuya section starts, as usual, at 2023424

Config in json format:

Thank you for sharing, can you also attach jSON template in OBK format? Because, you know, we would like to add device to our teardowns list https://openbekeniot.github.io/webapp/devicesList.html and it would be easier for us to just copy JSON, instead of making new one from scratch.
