Another Desk Motorized Controller

Best to post sample logs as code like you did with config. Easier for people to see and analyze.

I would post logs for various actions/stages. On boot. Up. Down. Other buttons.

I would initially analyse one wire at a time and focus on finding the desk height stream first. It’s probably the R wire.

See if you can find a pattern similar to the Desky height protocol…

This post is some info on the rj12 Bluetooth dongle port. I’ve been able to decode the UART height messages coming from the controller to the dongle port (building on sseib’s work). They are similar to the ones on the rj45 port. But there doesn’t appear to be dedicated wires for raising/lowering the desk on this port. You can see in the teardown link below that the Bluetooth dongle has 4 wires. Earth, power, tx and (very likely) rx. I asked the company for the protocol for controlling it but t…

Or the desktronic protocol.

Turn your Desktronic standing desk into a smart desk!

I also understand, that these are the segment-values. But this works only for the first decimal-position and the tens-digits, like you can see in this screenshot: [image] Interesting is, that at the Units, the last 4 bits are the same, but the first 4 ones are different. (0xBF → 0x3F; 0x86 → 0x06; …)

Once you identify the height messages you can move in to decoding them.
