If it uses more material than required for the job it's over-built and under-engineered. Your solution seems to be massively that.
Also, what positive safety control loop could a standing desk use?
I have yet to actually build anything that controls hardware, but I have been lurking, reading about microcontrollers, collecting little bits.
An actual application, a solution to a real problem or neat project, is the best way to make it real.
So like a led (light) is one lab. The next might be a photo sensor (signal with amount of light). After these two labs you can now make a night light. Or a rave strobe.
Do the switch or button lab and you can turn it on or off or change the pattern. After 30 labs you have a pretty good idea of what to do.
Now buy an esp32 that works with a breadboard and if you know basic http you now have an iot device.
I recently hooked an esp32 to a dht22 and started graphing temp in my gourmet mushroom enclosure in about an hour of watching baseball. Just sends data to influx and grafana on an rpi data hub
If I were making and selling some IoT hardware or if I wanted to re-use the RasPi for something else in my house, it would definitely make sense to move to an ESP/Arduino
I started with a raspberry pi, but then discovered esp32 with an lcd display for just a few bucks https://www.amazon.com/LILYGO-T-Display-Bluetooth-Developmen....
Plus your standing desk could also be a pi-hole for wifi security.
Replace the ESP8266 with some Arduino clone for 3.50 € and you'll even be more beginner friendly...
Cost, power consumption, reliability, performance, security, weight, and volume, to name just a few.
I really dislike the attitude that we should use the biggest hammer we can find for any size of nail just because we can.
Clever though!
Many times, an arduino or esp32 would be more than capable with considerably less power usage.
