ESPHome
Reddit take
Not enough linked mention summaries yet; the source excerpts below are the evidence.
Pros
- Someone recently posted a better solution with esphome. https://www.reddit.com/r/Esphome/comments/1hzpk48/fully_central_esphome_based_modular_wired_smart/
- You'd probably want to look at Tasmota/ESPhome flashed smart plugs, or Shelly.
- If you don't need alarm functionality and using home assistant you could use esphome, wire the sensors to an esp32. Few lines of code and you can use them in automations etc.
- A $15ish Broadlink RM4 Mini or an ESPHome IR blaster is safer and easier than soldering your main HVAC control board.
- esphome flashable kit would be my pick easy mqtt interface.
Cons
- you could use an esp32 with esphome to manipulate the pwm FAN signal of your ProLiant so it stays quit while starting.
- I'm feeding that into the Home Assistant energy dashboard through ESPHome.
- If you like to tinker, you could look into soldering the buttons to a ESP32 board and installing ESPHome to run it all.
- I tried ESPHome with a sensor to monitor water, but just couldn't get it to work.
- the esp32 with esphome installed will have a web interface that shows the measured values.

OP, if you figure it out, and you are comfortable with a little bit of hardware & software hacking, you can pick up a Sonoff RF Bridge R2, flash it with ESPHome, and pull that into Home Assistant since the manual says it’s operates on the 433 MHz spectrum.
I used a Kc868-a16 and esphome works a treat for about $35 aud
ESPHome is pretty great.
I’ve got a POC cobbled together using ESPHome and an interval block that works nicely.
