100%. Home Assistant has proven to be incredibly useful in my house. My wife loves it for the laundry notifications, the fact that I essentially replaced Life360 with it (Traccar, really, but it ties into HA so nicely), and the automated lighting: our basement (the younger kids’ play area), and themed lighting for the outdoor lights.
We’ve been fighting tangled toilet flapper chains over the last few years. The tangled chain keeps the flapper from closing, which causes the tank to continuously run into the bowl, which causes my water bill to skyrocket if gone unnoticed (we have 5 kids, 4 toilets, and the chains get tangled no matter what I do: new chain, longer chain, shorter chain, different type of chain/string/twine, etc… I blame the hard water). I finally got fed up, so I bought and installed a zigbee water level sensor for each toilet tank, then whipped up an automation which notifies us via Android’s “alarm_stream” notification channel if a sensor has been dry for longer than a few minutes. That channel overrides DND, and I am going to add an entry to ping my HA Voice thing as well in case we don’t have our phones on us.
