Automate Folding@Home With Home Assistant

[Lurick]

I recently got my network rack temp sensors working with Home Assistant and had a fun little project spawn out of it to start/stop folding on my server depending on the temperature in the rack and also time time. All of this is done on HAOS and might vary slightly depending on how you run Home Assistant

 

 

1) Run Command to Gen SSH Key:

ssh-keygen

 

2) Copy SSH Key to Remote Server:

ssh-copy-id username@192.168.x.y

 

3) Copy SSH Keys to Config Folder:

SSH Keys need to live in /config/.ssh/ instead of /root/.ssh/ for shell commands

cp /root/.ssh/id_ed25519 /config/.ssh/id_ed25519
cp /root/.ssh/id_ed25519.pub /config/.ssh/id_ed25519.pub

 

4) Create Shell Commands:

nano /config/configuration.yaml

Add in the following where you see fit, end of file is good:

shell_command:
  folding_start: ssh -i /config/.ssh/id_ed25519 -o StrictHostKeyChecking=no username@192.168.x.y 'fahctl -a 192.168.x.y fold'
  folding_stop: ssh -i /config/.ssh/id_ed25519 -o StrictHostKeyChecking=no username@192.168.x.y 'fahctl -a 192.168.x.y finish'

You might be able to get away without "-o StrictHostKeyChecking=no" but if you get Error 255 in the Logs on Home Assistant then add it in

 

5) Reload Home Assistant

6) Create automation in home assistant as needed

 

 

 

Example automation in Home Assistant:

Additional HA automation:

Plex runs on the same VM that does folding so if folding is active and plex is transcoding, pause folding. If transcodes drop below 0 then resume folding
