Possible to use for climate control or just heat/cooling?

[mfiano]

I have a small indoor room I use for growing chili peppers, and my hardware consists of therometer/hygrometer sensors hanging in the room, passively transmitting values over bluetooth every few seconds. I also have a heater in the room, and a large inline exhaust fan pulling air out of the room, with a passive cool intake hose as well.

I was writing some PID management code outside of HA to handle this, and, I gave up, eventually finding it more accurate to measure the extrema of the past sample to use for an estimation as to how long to keep either the heater or exhaust fan running.

Both air temperature and humidity are two separate set points I require, without much variation (no range, so I would like to be as stable as possible). Additionally, they become different set points during lights out period, when my pepper plants are sleeping. One thing that is annoying, and may require fans to be aware of heat values, is relative humidity is a function of temperature. If the fan is not spinning and the heat is on, it will likely start spinning soon quite fast, as there is more moisture capacity with higher temperatures. If the fan is spinning and the heater kicks on, the heater will be running for longer, and may not get to fully reach its target. My hacky software deals with making these two things know about each other, and works with ~1-2F and ~2-3% RH fluctuations, and I'd like to do better.

I am wondering if it is possible to use this plugin to control both the temperature via the heater, and the humidity via the inline exhaust fan. Looking through the documentation, I only see heating and cooling devices, and no fan. I've only been using HA for a couple months, and was able to mimick my independent software program with dozens of virtual sensors, templates, and automations. It is obviously not scalable, so looking to improve.

Thanks for your help in advance!
