Figured you guys might enjoy my little winter project. I have an always-on server + my gaming PC in my office set up with xmrig. I have electric baseboard heaters in my apartment (PNW, USA) so as long as I’m not heating my office past my normal setpoint the electricity is essentially free.
How I set this up:
- ESP32 flashed with ESPHome + MCP9808 temperature sensor takes a reading of the ambient temperature every minute and sends it to homeassistant
- Homeassistant feeds that temperature (as well as a controllable setpoint) to a python script
- Python runs a PID controller based on the room temp and setpoint
- I use the XMRIG http API to pause/resume and dynamically control the number of threads used for mining
Here’s the result:
Keeping my room +/- 0.5 degrees from the setpoint while mining
If you guys are interested I can post more details. I’ve had my baseboards off for over a month now with outside temps below freezing.

Random Helpful Tip: The heat dissipation of a 3GHz Pentium 4 CPU is not wasted if your room is freezing cold, as mine is right now. I’m tempted to overclock it in order to warm the room up some more.
Very cool (or warm in this case). I have xmrig running too but i need more machines to maintain the temperature in my ~144sqft bedroom. I currently only have ~200w of heat coming out and need more like ~500 so i still need to run the heater but am able to run it less often.
I actually have GPU mining set up and it kicks in if needed. Not an efficient way to mine monero but it’s an efficient way to heat the room!

This is brilliant; I love it.
