Nearly all of this is provided by my (fairly standard European) Thermostat from Junkers, where you can define a "warm" and "cold" temperature-setting, and then set timeframes to switch between those settings for each weekday (individual or ranges like Mon-Fri).

Exception is the "Make it a bit warmer for 2 hours" button (which leaves alot of room for interpretation and error, i.e. what is "warmer", should the 2h start while still heating up, WILL it even heat up within 2 hours,...), but that is more or less achieved by just rotating the dial, as whatever is set will be overwritten when entering a new timeframe...

Nothing fancy in there, no Wi-Fi or anything, just a display, a dial and a few buttons under a lid.

I configured this once, and all I do is move a switch from "automatic" to "permanently cold" in summer to stop it from switching to heating

My Hive thermostat does exactly that.

Per radiator.

With as many times as I like (so the kitchen comes up to 19c during the week from 7-8 in the morning and from 6-8 in the evening).

Oh, and it turns off when the window opens, and back on when the window shuts. So my wife deciding she wants it cold doesn't cost us a fortune.

I get where they are coming from, a simple interface like that would nice. It's annoying having to dig through menus to set a schedule when most people set the same exact schedule: a daytime temp and a night time temp, with slightly varied times on the weekend. I know I do. If you need more finer grained control, then this is not for you.

The place I'm renting has this thermostat: https://www.honeywellhome.com/us/en/products/air/thermostats...

here's a video showing how to program the one I have: https://youtu.be/-yGtoDOXpPY?si=PQgv1wO8-ztz2-xt&t=58

To program it you need to tap: Menu -> select -> arrow button -> select -> select -> select .... and at this point I stopped tracking because you get the point

Not saying that the "Dream Thermostat" is perfect, but it's heading in the right direction.

I have a Honeywell thermostat with companion app. It’s trivial to configure compared to traditional thermostats, even the UI on the device itself is pretty simple.

Problem is with the proposed thermostat here is thst it’s covering a single type of schedule. These products need to be able to cater for all sorts of variations.

At least with mine when you configure in the app on your phone it is very clear what you’re choosing.

> It seems to me that using home assistant to implement this is fairly feasible.

Is this too much to ask for one thing to do everything it supposed to do and not self-host some python nightmare?
