Yes smart thermostats are great. I live alone and have a somewhat random schedule. Being able to turn on the heat before heading home is a total game changer. If I’m away when I’m usually at home, I can change the schedule in advance, or change it when I already left if I forgot. This helps save money. It can also track usage, so you can double check your energy bill with your actual usage. Although I have a Homeassistant setup with sensors to track usage from the meters, but still a useful tool to have. If you use gas for example for heating and hot water, the thermostat can give the data needed to split up the gas bill between those and see where savings are to be had. It’s also an extra temperature and humidity sensor, keeping track of how comfortable your home is and it’s possible to act not just on temperature, but other factors as well. I have a bunch of temperature sensors scattered in my home and the curves are useful for tweaking heating and ventilation in the home. Giving an optimal balance between cost and comfort. And preventing things like mold, which might save on heating in the short term, but put on costs in the long term with health issues and mold damage.
I have a lot of automation, but I have one rule. Everything must still basically work when the internet is out or the home automation has issues. So I use physical switches with sensors and relays, when everything fails the lights will still turn on and off with the switch. If there is no internet, physically turning the thermostat up or hitting the big override button next to the heater still turns on the heat. Stuff like that is important, it’s a luxery and a convenience, but it must never become a hindrance.
I try to use open source stuff where I can and have contributed to some projects. I’ve made stuff myself like sensors with self made pcbs in 3D printed enclosures. But I also use some proprietary stuff, like for example the Nest thermostat. I bought it about 10 years ago and mostly because I loved the design. This was when they were recently acquired by Google and were still fully autonomous. Back then there weren’t many alternatives and the Nest was by far the best looking one (imho). The software absolutely sucks, the old Nest app didn’t get many updates with Google, but the older models still only work in the Nest app. But with Homeassistant I can work around most of it. It’s a shame because Nest had so much potential and was doing good stuff, now under Google their product are kinda meh.
What do you use for temp sensors? Every once and a while I’ll look into temp sensors then give up after I realize I have no actual clue what I’m looking for.
I’m currently using a lot of those mini hygrometer sold under a lot of brands. Mine are branded Brifit, but I’ve seen other brands like Oria and Ankilo and many others.
Here is a listing from Amazon, please don’t buy it there, but to get an idea of the price and the specs:
They use bluetooth and are powered by a little CR2477 coin cell battery, which lasts about a year (varies a bit, I’ve gotten some to last 10 months, others 14 months). I bought a bunch of them at once, which drops the price a lot. I’ve been using them for about 2 years now and they seem to be accurate and report data often (every few seconds). They are very small and can be tucked away somewhere (be sure they get good airflow tho, so it measures correctly). They are strictly for indoor use only.
My Homeassistant server (tiny old Intel Nuc thing) is pretty central in my home and I have a USB bluetooth stick attached to it. It’s on an USB extension cable to have the antenna of the bluetooth stick out of the enclosure it’s in for better reception. The sensors are scattered throughout the house and all seem to have an excellent connection. The USB stick I use is a UGreen one which is very common, with excellent support in Homeassistant.
I think this is the stick I have, at least the picture matches, again please don’t buy from Amazon.
Stop buying into the locked-in smarthome appliances… there’s far better, more open Tools and Smarthometech that is way better.
Care to give some examples for alternatives?
Anything recommended by the Open Home Foundation or partners with Home Assistant
I have a Sensi thermostat. Highly recommended.
My sensei touched me in my no no place :( don’t recommend
Never looked into buying any smart home stuff, seems like a waste. Are there some that are worth it?

Hm. Yes. I don’t own a home but I would like to subscribe to your newsletter.

UGreen stuff is pretty good and sold in a lot of places.
Both the bluetooth stick and the sensors are China special, but these days it’s very hard to find anything that isn’t. Quality seems great tho.
