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.
I never thought about temperature/humidity sensors! I know some gardeners that use them in various greenhouses, but that’s interesting stuff. Is there anything yall’ve learned about the power efficiency of heating/cooling methods? Currently we’re making a lot of baked goods and stews to keep the house warmer and more humid, but I don’t have any data on actual power use changes.
Check out Technology Connections on YouTube. Specifically this playlist on heat pumps.
The only thing more efficient would be mechanized Solar shades and passive techniques.
I’ve had a temp/humidity temperature in all house rooms for a few years now, and it’s dead useful.
Balancing the radiators and TRVs so everything heats up evenly.
Spotting anomalies (top floor loses a lot more heat when the wind is blowing)
And setting the flow temperatures for the radiators, as I can see the rate of heating compared to outside temperatures.
