I would use HA only to get off limited/bad "smart home" apps, but we've been using it in my home for ~6mos for a handful of things and we love it. Probably gonna go ham this year: switches, sensors, the whole thing. I think my most in-depth project is wiring up some temperature-sensitive PWM fans inside an IKEA cabinet that houses a bunch of tech stuff (gaming consoles, voltage converter, modem, router, HA machine, laser printer, etc) to keep it from overheating, which I'm very excited to get going on. Other pie in the sky plans/ideas:

- Wireless plant water sensors

- Blind/curtain management

- Ventilation management based on PM/VOC/CO2

I'm not that into smart locks or doorbell cams... or cameras in general? Feels a little creepy, but I can see the appeal I suppose.
