Successful day.
Finished installing an extractor fan in my basement to battle damp. And I've plumbed it into Node-Red (first real use of NR) to control it based on time of day and internal/external humidity. This involved deploying an ESPHome device (I'd already made it), a Xiaomi Bluetooth gadget, and fixing TLS for my MQTT broker.
Tomorrow I'll look into turning off the fan if the TV is being used (the fan is bit noisy in the lounge as it is under the lounge floor).

I was a bit surprised to find the fan wasn't running this morning. Checked the Node-Red flow and found that the outside humidity is 73%. Turns out the logic is working as it should.

@puck Nice DIY project. A couple of years ago I replaced my bathroom fan with the Lunos Silento, which does automatic humidity control. It's running all the time but very quietly and ramps up when it detects a certain level of humidity and then goes back down again. I love it. https://www.theheatingcompany.co.nz/home-ventilation-systems-nz/extractor-fan

@anitsirk That is a nice solution!
I plan on doing similar for my bathroom, but controlling the existing fan.

@puck it'll make a world of difference. Most bathroom fans are not doing what they are supposed to do.

@anitsirk They also make a "nasty noise" so no bugger in our house ever turns them on. @puck
