Thermostats are Barney basic in function, touch the red to the hot to call heat, red to yellow for cool, and red to green for the fan, then open the circuit when the temp is where you want it. Kinda sounds like a fun project.
It’s actually surprising that we expect so much from a smart thermostat. Wouldn’t it be far smarter to sell a dumb thermostat on a local iot network and put the smarts in your automation hub? People who want the extra functionality would be good with that and people who don’t would appreciate saving the money
I could see that, but you have to remember that the average consumer doesn’t have an automation hub or get deep into the automation sphere, and as such many of these products are designed to be standalone devices that can be controlled from a phone. Often enough they can be the only ‘smart’ device in a home.
That all said, a dumb thermostat like your suggesting would still require a small CPU, ram, embedded OS, and network stack/hardware to operate and communicate, so I don’t know how far the savings would go. I can’t imagine the processing power on something like a nest is that powerful as it is.
I’m sure not much: Amazon is not likely taking a loss on all those $50 Echo Dots, but that’s a lot more than a thermostat needs. It’s also on WiFi and can play streaming audio, so that’s not nothing
I had no idea it was that simple! How do you control heat pumps? I know they have a setting where if outside is too cold it runs backup electric or gas.
If its a cheap crappy one, the compressor is on/off depending on temperature. Decent ones will have a VFD to manage the load of the compressor so it doesn’t have to turn on/off all the time but just regulates the compressor load to match heating/cooling requirement. Both have their own controls, and you generally shouldn’t mess with them.

My Ecobee not only has some fairly sophisticated software, a touch screen, and remote sensors, but enough CPU to run Alexa
I’d be curious to see what system resources are required for Alexa
