I’ve been using HA for a while; having my home just “do things” for me without asking is fantastic. My lights turn on to exactly the levels I want when I enter a room, my grass and my plants get watered automatically, heating and cooling happens only when it needs to. There are lots of benefits. Plus, it’s just a fun hobby.
One thing I didn’t expect, though, is all the interesting things you can learn when you have sensors monitoring different aspects of you home or the environment.
- I can always tell when someone is playing games or streaming video (provided they’re transcoding the video) from one of my servers. There’s a very significant spike in temperature in my server room, not to mention the increased power draw.
- I have mmWave sensors in an out-building that randomly trigger at night, even though there’s nobody there. Mice, maybe?
- Outdoor temperatures always go up when it’s raining. It’s always felt this way, but now it’s confirmed.
- My electrical system always drops in voltage around 8AM. Power usage in my house remains constant, so maybe more demand on the grid when people are getting ready for work?
- I have a few different animals that like to visit my property. They set off my motion sensors, and my cameras catch them on video. Sometimes I give them names.
- A single person is enough to raise the temperature in an enclosed room. Spikes in temperature and humidity correspond with motion sensors being triggered.
- Watering a lawn takes a lot more water than you might expect. I didn’t realize just how much until I saw exactly how many gallons I was using. Fortunately, I irrigate with stored rain water, but it would make me think twice about wasting city water to maintain a lawn.
- Traditional tank-style water heaters waste a lot of heat. My utility closet with my water heater is always several degrees hotter than the surrounding space.
What have you discovered as a result of your home automation? While the things I mentioned might not be particular useful, they’re definitely interesting, at least to me.
What’s even more irritating to me are the random changes to the TV’s UI. Turn it off for a while and I come back to an entire new set of menu entries and ads!
Home Assistant, OpenWRT and Adguard Home mostly fix those problems.
When my TVs are powered off a Home Assistant automation enables a couple of OpenWRT firewall rules. Those rules block all TV Internet access. When the TVs are powered on the firewall rules are automatically disabled and the TVs work normally. That along with Adguard Home’s blocking of all UI ads makes my TVs almost user friendly.
That’s a neat rule. Thanks for sharing!
Couldn’t you achieve the same effect by just having a PiHole?
Adguard Home is a Pi-Hole competitor. They work fine for ad servers, but the content I was trying to reduce couldn’t be blocked that way or the TV’s wouldn’t work. Menu changes were being loaded while the set was off and Roku was inserting some ad content along with menu changes.
To my surprise this setup has reduced menu additions and ads to almost nothing. It seems that these menus aren’t updated when my TV’s are actually in use and that’s now the only time they can connect to the Internet.
