Hi Coolie,
I had a few issues getting this going too, but managed to figure it out in the end.
- Install the HassOS Serial Configurator
- Disable Protection Mode. This was the fix for me, as I couldn’t get it to work without doing this.
- Start HassOS Serial Configurator
- Monitor the HassOS Serial Configurator logs. You should hope to see something like this.
- Pull the power cable out of your DeskPi, or hold the power button for >3 seconds ie. hard power off
- Power on DeskPi
- Once HassIO has restarted, install DeskPi Pro Active Cooling
- Within DeskPi Pro Active Cooling, click on Configuration and configure your options. The Serial Device should be as shown.
- Save your config and start the service.
- Check the logs for DeskPi Pro Active Cooling. It should now show you your temp readings.
- Once everything is working correctly, go back into Supervisor and uninstall HassOS Serial Configurator
I hope this helps!
