Why would you want to cram 50 so called "smart" devices is the real question. Is your quality of life improved by having your lightbulbs and switch connected to the internet. Why do you need sensors at all?

My home is completely analog, like I even have to operate my windows blinds manually. I have lived in a totally connected and electrified house and I didn't view any improvement in my quality of life. Only downsides when the power grid had an issue.

Well, if you want an example, I have about about a dozen PM and CO₂ sensors spread around the apartment, and some outside of it. I live in an extremely polluted area and it allows me to make decisions on when it's (relatively) safe to open windows (or even inside doors if it's really bad outside).

PM 2.5 may be in the range of a couple micrograms/m³ in one room (with air purification) and 100× that in the other adjacent room, so it makes sense to have sensors everywhere.

Still very far from 50, though.

My quality of life is improved by heating that can be turned on remotely (while im on my way home) or on a timer (before i wake up).

Lightbulbs not so much.

You don't need to have it internet connected to have your thermostat on a timer. My home has responded to heat or cool the house based on when I wake up, when I leave, when I come home, and when I go to bed for well over a decade all without needing an internet connection to do so. My thermostat doesn't go dumb just because the internet went down or because it became unsupported and got bricked.

The only thing I wish it would do would have better multi-zone temperature and humidity sensing to know to turn on the circulation fan when the edges of the house get too hot/cold compared to where the thermostat is. Even then that doesn't require the internet, it could be done with cheap 433MHz temp/humidity probes running on button cell batteries for years.

I do need internet if i want to tell my heating to turn on 1hr-30 mins before i come home though.

Or to respond to the weather (e.g. start warming the house earlier coz it's a particularly cold day).

If your life is very strictly regimented maybe it's less useful.

This doesnt mean I want a cloud connected thermostat. I want something that talks to homeassistant.

I tell my thermostat my schedule once and how I want my house to be, and it makes sure to hit those temperatures when I want it to. I shouldn't have to "tell it" I'm coming home, it should just do it.

Respond to the weather? Its a thermostat. Even a decent bi-metallic strip thermostat will "respond to the weather". Its not like the thermostat needs to do anything different if its an especially cold day outside, it will keep the indoor environment as you programmed it. How do you think thermostats worked before the internet?

The only "respond to the weather" idea I'd like would be to account for especially humid days as sometimes the temperature is fine but its really humid in the house. But once again it doesn't need to reach out to an API to figure out the humidity outside at some airport 20mi away, it just needs a local humidity sensor.

If I am not in the house or I am asleep it is a waste of energy to heat it.

I find it weird that you get indignant at the idea of a little more automation than a timer.

>How do you think thermostats worked before the internet?

Either wasting money heating an empty home when I went out or I came home to a cold house and then turned on the heating. I remember.

I also remember thermostats which didnt understand the concept of weekends, etc.

> If I am not in the house or I am asleep it is a waste of energy to heat it.

I agree, which is why I use a multi-stage programmable thermostat. Once again, it turns off when I leave, turns back on a bit before I get home, lets it warm/cool a bit while I sleep, and then starts back up around when I wake up.

> I find it weird that you get indignant at the idea of a little more automation than a timer.

If you're manually telling it you're on your way home that sounds like less automation to me. Personally I'd take the tiny bit of efficiency hit having it heat the house maybe an hour or two off from my regular schedule than having to micro-manage turning my thermostat on and off on a more expensive device that will probably be eventually bricked.

I'm just saying, the vast majority of the quality of life improvement from your internet connected thermostat could have been achieved with just a 7-day 4-stage programmable thermostat that has existed for 20 years. Its nice you're happy with your expensive device that's beholden to some cloud server, I hope it stays online for a few more years.
