Is that actually an ethernet port, or is it just an RJ45 for something like I2C, UART or some other protocol? It's also got a little port for a Bluetooth controller, which came with my desk. I bet it's possible to reverse engineer whatever protocol that is using over bluetooth/BLE.

This. It's not Ethernet. This article has some dissection of the data going over those ports: https://hackaday.io/project/4173-uplift-desk-wifi-link

I bought one of these https://www.upliftdesk.com/bluetooth-adapter-for-uplift-desk... but the app UX was not my favorite. Fortunately someone decoded all the BT commands so I made https://github.com/dylanowen/uplift-cli and connected that to a schedule and cmd+enter. It's great to just type stand to stand

boy do I have just the thing for you (disclaimer: I have nothing to do with, nor have I tried this): https://www.tindie.com/products/tjhorner/upsy-desky/

if your standing desk has that ethernet like connection scheme, something like this might just work out of the box!

Some details at https://upsy-desky.tjhorner.dev/docs/reference/compatibility... including a sketch of what to do to add a model to it. The rabbit hole beckons

I have this and it works great. I wrote a script for it that checks my google calendar to make sure I'm not in a meeting (nothing worse than your desk suddenly moving positions when you're in the middle of talking to folks) and then moves my desk to a standing position for a configured amount of time every day. https://github.com/signalnine/upsy-desky-autostand

Gostand does as well. Hmm. Would they have bothered encrypting data going across that wire? Seems unlikely. Would using actual ethernet have been cheaper than DIY? Really might be. Interesting thought, I do want to toggle the desk height from emacs and probably from cron
