Home assistant currently version support Raspberry pi compute module 4. Can we use this for dedicated hardware for the Home Assistant.
Why compute module?
- Raspberry pi 4 full computer that has lots of interfaces that we don’t need to run Home Assistant
- Always limits how many Raspberry pi you can buy in a months
- Any other single board pc is more expensive
What’s in my mind?
Using compute module 4 + PiTray mini

November’21 Update: Due to current silicone chip shortages expected delivery time for the CM4 units is around December. i have to hold this testing till i have got CM4 in Hand.
February’22 Update: Now I have CM4 with eMMC and i mange to install Home Assistant.
