I did. I haven't sorted out proper ventilation for my laundry room yet. Using a pi zero with a dht22 to control a dehumidifier via a tradfri power switch when needed was quick, fun, functional, and offline with no vms or GUIs needed.

Logging the data elsewhere to influxdb was a fun little addition for a few pretty graphs.

I'm a fan of nats.io but it isn't necessary. A private network via zerotier makes life easy but is also completely optional.
