What I'm trying to do is use the temp sensor on the MPII in the same way as one can with a Ruuvi. Is that possible? If yes, how?

Can I use a MPII temp sensor for switching a fan by relay?
I'm less familiar with setting things like this up natively using assistants but node red could solve this pretty easily.
I do similar but rather than temperature i use solar power. If above a certain limit i turn on a shelly smart switch connected to water heater.
Same concept as yours except you'd use temperature and a fan. Rather than solar data and a water heater.
