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 can see if someone is on the toilet and having a Nr.2 by checking the power draw of the Japanese style toilet. (I also have a presence detector). I do not monitor the first part intentionally, though.
I unintentionally catched some birds eating on camera and that led to us installing a designated bird cam - in a 3D printed bird house. The AI model for identification is still in the works though - there aren’t any good European based ones available as open source so I still will need to work out my own.
I found out the kid is reading FAR more than thought and is using the PC far less than I thought. Sorry kiddo!
CO2 is going up far more than expected,yes. What I found more interesting, though, is the direct connection between the humidity and my sinus infections - I always get them if my room air gets to dry.
Cooking releases an ungodly amount of VOC and uses FAR more electric energy than I thought.
And: After two years of optimisation I can control the temperature in two very sun exposed rooms just by using the covers and a weather forecast extremely well. Means they are up to 4° colder in the summer than before and 10° warmer in winter. Sadly this does not apply to all rooms.
And last but not least: Heating is the only point where home automation really saves energy here.
I had a terrible run of sinus infections last year so I’ve been using a humidifier and been checking the humidity in the house daily this winter. What percent range do you find is ideal?
I try not to go below 47%
Do you have induction hobs or traditional electric?
Induction
Huh, I figured induction would be cheaper.
I have no comparison to conventional electric - it might still be cheaper with induction. But I use induction for 10 years now, exclusively (and had gas before that).
But it’s the general cooking as well. Two ovens (One with steam,one conventional,of course not always used together,but it happens), other kitchen stuff, it is fairly interesting how big the peaks are that are created this way. And don’t get me wrong - our kitchen is kind of a upper market one in terms of appliances (the wood on the other side is run off the mill and was dirt cheap),but it’s also the thing that brings my family daily joy and I am more than happy to pay the power bill - but nevertheless I am still surprised.
Did you try BirdNET Pi?
Bird-net pi also runs here,but it provides audio identification,not optical identification.
Was going to suggest this - I’ve not used it myself but friends have and the model apparently does have fairly good results https://github.com/kahst/BirdNET-Analyzer
You know what, I’ve just checked and birdNET app is the one I use in the field, I thought I was using something from eBird. BirdNET is great for UK birds, I use it all the time! I’m an ecologist doing bird-stuff
