Desktop AC controller
One desktop panel for two air conditioners that only had a phone app.

The problem
My two portable air conditioners can only be controlled from a phone app. There is no desktop app, and I do not always have my phone on me.
What I built
A small desktop panel. Each unit has its power, temperature, mode and fan controls, and there are buttons for all on and all off.
It uses the maker’s official connection. It also has a practice mode with fake units, so it can be tested without touching real devices.
The result
I can control both units from my computer. I use it about once a month.
What this could save your team
If a device or a service you rely on has no good screen for your way of working, a small panel can be built on top of its official connection.
