Information

Device used: Conrad Renkforce Wireless socket

It's based on the SC5262 (encoder) / SC5272 (decoder) pair that uses a common fixed code, 3-byte protocol.

Sniffed data

I'm posting the output of several commands. The raw bucket decoding works and converted B0 commands also work. The issue is that nothing works outside raw sniffing, but the chip should be supported in theory. Normal supported code sniffing produces random results.

Currently it's not possible to assign actions to remote buttons in HA. Additional info: code group 2 is selected with the slider switch, and button 3 "ON" is used for testing.

This seems a bit more consistent, but still can't reliably capture the code. Note that capture with A6 only works if I first issue the A6 command, and the the A1 command. Then on the first reception, it beeps and responds with an A3 timeout similar to the one in the above log excerpt, which should not be the case as I started a different kind of sniffing and the A3 response shouldn't contain a payload.
