On the other hand, HA tends to act as an attractor for this kind of stuff. I installed mine first to play with Hue lights, then to try and add my A/C units to it. With the latter turning into a spectacular success (infinitely better than vendor's garbage app, plus actually liked and used by my wife), HA now also runs hacked IKEA air quality monitors, floor heating, and most recently, reports when the washing machine is done. It's now pretty much critical infrastructure for us.
