I just replaced my old standing desk with a FlexiSpot E7 Pro with one big question in mind.
Can I get this thing into Home Assistant?
I ended up testing a new FlexiSpot version of the open-source DeskUp project from SmartHomeGuys. They did the hard work on the integration and I had the privilege of testing it on my E7 Pro.
The FlexiSpot uses RJ45 and a different protocol than their existing version, but the hardware for my prototype ended up being surprisingly simple. An ESP32, a short Ethernet cable, a few WAGO connectors and some Dupont wires.
No soldering. No custom PCB. The desk even powers the ESP32 itself.
Once it was running ESPHome, I had the desk in Home Assistant with height, movement and idle information along with controls for the desk itself.
And of course, getting it into Home Assistant meant I had to automate it.
My coffee routine now checks whether I’m sitting or standing and changes the desk position when my coffee is ready.
Completely necessary? No. 
But it has actually gotten me standing more.
I wrote up the full project, including the desk, the ESP32 prototype, the Home Assistant controls and what I ended up doing with the automation.
Five Years, Five Hours Standing. Then I Got a FlexiSpot and Made It Smart.
I’m curious what other people are doing with standing desks in Home Assistant. Once HA knows the actual desk position, there are a lot of interesting directions you can take it.
