If you’re trying to avoid a whole zigbee or zwave network, Govee makes some inexpensive battery-powered bluetooth thermometer/hygrometers, and have a HA integration, but bluetooth can be tricky to get running on Pis. I feel like most of the actual wifi devices are phone-home type setups. My govee thermometers have pretty good range - one of them even reads from inside the refrigerator.

I don’t so much care where it’s made. The real selling point, to me, for Pi is that their products are well documented, in English, and solutions for problems are easily googled. There’s tons of SBCs out there, some of them even inexpensive, but I can’t tell if any are going to last longer than a single production run. Meanwhile, I can still buy a Pi 3 after almost a decade. Or I can take the hat I made for a Pi3, plug it straight into a new Pi Zero, and expect it to work without changes.

IPO is a big step down the path to enshittification, especially when there’s no clear, dominant alternative.

I can see that. Most of my house gets enough light - or streetlights at night - to walk through with the lights out at midnight. Add in a lumen sensor, though, to dial lights up when it’s cloudy and down when it’s sunny…

When I think of automations, it’s either things like coordinating big power draws to cheap electricity or trivial quality of life enhancements, like turning out the lights in an empty room. The latter, I have trouble justifying to spend on occupancy sensors and smart switches if it’s only going to save 20 Watts of LED or five steps. Once it’s become your hobby, it’s much easier to say, “I’m going to buy these sensors because they’re fun to play with and it gives me joy to see them work.”

I didn’t think I was. I got sucked in by sensors to monitor indoor temp, humidity, air quality… A smart switch to turn lights on and off when I’m not home. Now I’m thinking of how to turn the HVAC fan off when IAQ is good and temperature is comfortable. I’m not ready to have the house turn lights on when I enter a room or start the oven when I get within a mile of the end of my commute, but it’s been growing, one $30 gadget at a time with no subscriptions and no data leaving my LAN.

This is exactly the kind of semi-ridiculous thing I like about home automations: the power to answer one’s most trivial curiosities.

I’d probably add a logger, so I could follow the history of Mohkno’s food thievery, then try different techniques to discourage her. Have ha also play a recording of you saying ‘Mohkno, no!’ Some activity to distract her during the critical food-stealing window. Or go all-in and get those microchip-reading pet feeders.

I have a ‘roll-your-own’ using an adafruit SCD-30 module https://www.adafruit.com/product/4867 IR-based CO2, temp & humidity; I2C with python libraries, so integrating it with an RPi is easy. Sensor is self-calibrating over time, so if you leave it in a higher CO2 space with no exposure to fresh air, it will eventually drift such that the lowest observed CO2 reports as 420 ppm. Newer SCD-40 is only $45, but different sensor technology.

Dunno about their shipping outside the US.

I would rather spend (modestly) more time checking my own than less time standing idly with nothing to do but watch some kid checking out my goods. It feels better to be an active participant. Where it breaks down for me and my 12 items is when all the self-check lanes are clogged with people trying to ring up a full cart of groceries, who still haven’t figured out how to work self-checks, who are encumbered by a baby in one arm and a phone in the other hand, or who just can’t move all that well.

Managers using the presence of self-check as an excuse to understaff the actual checkouts makes all of those problems worse, and makes the checkout process suck for everyone.

I’ve never been in a coffee shop without an automatic/one-touch espresso machine. The last one I tried - a place that roasts their own beans and offers a range of classes and Specialty Coffee of America certifications - I asked if they could make me a “bad” espresso, and they basically said, “Nope, you’re gonna get whatever the button gives us.”

Some of that turn is physical plant. Kitchens, especially, are built to serve human forms, where tech solutions to food prep would rather be stand-alone boxes. It’s a far harder problem to make a robot that uses a restaurant’s existing grills, ovens, and deep fryers than it is to make a box that turns out perfect french fries. It’s a riskier proposal for a restaurant to replace its fry station, where a human can make fries, onion rings, egg rolls, or whatever new fad hits tiktok, with a fries-and-rings-only box with less than 10 years commercial proof. Generative AI, for all its faults, is just code that runs on a computer you already have, or maybe in a cloud service with zero physical footprint. Relative to replacing your barista with a vending machine, trying ChatGPT for a quarter or two is practically zero risk.

I pulled the latest HA version based on you comment in this old thread, and you’re right! There is a restart button now. Thanks.

Collecting and comparing environmental data was the whole reason I started homeassistant. I mostly use indoor sensors and compare with national weather service for outdoor, but I like seeing the data. Graphs of indoor/outdoor, next to https://cdn.star.nesdis.noaa.gov/GOES16/ABI/SECTOR/se/GEOCOLOR/600x600.jpg (which updates every 5 minutes) I live in the US Southeast, and the indoor/outdoor comparison, especially dewpoint, lets me know when it’s ok to open windows overnight. i.e.: the overnight temperature usually drops below the A/C set point, but if that’s going to draw in a bunch of humid air, it may feel more comfortable to keep the warmer, drier air. Actual, local outdoor conditions would be even better, because we do get localized summer showers that really raise the humidity in very small areas, and the NWS data comes from an airport 5 miles away.

I’d love to have some motorized windows, or even blinds, for automation. Absent that, there’s nothing super obvious to me to trigger off environmental data.

I have HA running in docker on a Pi 3 and Z-wave JS running in another on the same Pi. Added a purpleair integration for outdoor air quality, national weather service, some local sensors, and sql to get data from another node. People have made me paranoid about SD card failures, so I regularly image it to my main server. I mostly use HA to visualize environmental data, but it also runs the lights in a hydroponic farm and the house during vacations, via z-wave outlets. Have not tried to integrate it with google or amazon.

The only inconveniences I’ve found with docker is that you can’t restart HA from its web interface and, if you update regularly, old images quickly fill a smaller card, so you have to remember to purge.
