Exactly what I wanted
For Upsy Desky
I figured I was going to have to develop this myself, but was super happy to find someone had already done it. And done it well!
It was trivial to get the device on my walled-off WiFi network and then poke it with curl. I wanted this so I could automate raising my desk to standing height overnight so that I stand in the morning. I lower the desk around lunchtime, but if I come in the next morning and it's already at sitting height, I'm likely to just sit again. Being able to raise it overnight helps me avoid just taking the easy path.
I printed my enclosure and used the included hardware. Stuck it to the bottom of the desk with some double-sided tape. Made a tiny patch cable to keep it tidy and I'm super happy!
