I’ve largely avoided smart home hue bulbs and such. My holiday lights are on a timer. I don’t want to turn them on an off via my phone.
I did recently purchase an Airthings View Plus to monitor radon and air quality. A side effect of that was realizing that the dehumidifier in my basement is underperforming. Now that the monitor is there, I am thinking of using a smartplug and a fan to try and help with airflow.
When humidity is above 55% turn on shop fan—something like that.
