Feature Request: Nodered disable fan, get internal temperature and control aux relay

I would like an option in Nodered to disable and enable the internal fan and also to read the internal temperature. Beside that it would be helpful if the aux relay can be controlled from nodered.

Reason for this is that during night time it is very uncomfortable to hear the whining fan of the multiplus 2.

By reading the temperature I can enable a quiet external fan using the aux relay when the internal temperature rises.
