If you have no room for a thermostat on the wall, you can replace the switch with a smart switch, can be zigbee or zwave , etc. you will need a controller. You can then put a temperature sensor anywhere in your home and set the smart switch to turn on/off based on the temperature read of the temperature sensor.

I can't tell if this is the size of a light switch but it looks about right-
https://www.amazon.com/Honeywell-Premium-Baseboard-Thermostat-YCT410B1000/dp/B000TKFQF0/

Typical thermostats use low voltage and operate as a relay switch - the thermostat you'll need has to be 110v/220v (usually found for baseboards). But the issue is that they don't have a "fan only" setting, so either the heat+fan will be on or both will be off. I've set up a digital thermostat to replace a broken dial on an old A/C, which worked like a charm, but definitely doesn't fit in the space that an ordinary switch.
Item Dimensions LxWxH   9 x 7 x 4 inches.
I posted it above.
a typical wall plate is 3x5

Thanks, I noticed that and found a couple of others in the "similar items" list... added it to my post, and someone else beat me to finding it

For the timer/scheduling I'd just get a Wi-Fi light switch I'm not aware of any thermostats that fit into a light switch space
Right, that's the part I'm struggling with. Maybe it doesn't exist, but that seems strange to me. I'd think there are some retrofit situations where it's cleaner to use the existing space on the wall, but I haven't found a product for that yet.
I'm sorry I just looked at the shape not the dimensions.
Np, thanks anyway.
Does the switch control the entire thing or is the heat fan and light split between different switches?
I'm not sure if your interested but there are easy ways to set such a thing up with some DIY stuff.
It's 3 separate switches, currently a full size switch for the light with the second slot sharing switches for the fan and heater. If I found a solution I'd swap the light and the heater so I could dedicate a full slot to the thermostat.

Honeywell TL7235A1003 Line Volt Pro Non-Programmable Digital Thermostat with Electronic Temperature Control, 240-Volt - Programmable Household Thermostats - Amazon.com ($29.46)

This one seems to be the right dimensions HxW for a wall plate, although it will probably stick out a bit.
Did you check out this one:        Item Dimensions LxWxH   0.75 x 2.75 x 4.75 inches

You can get a 3 gang zigbee switch

a zigbee temperature sensor
https://www.amazon.com/Temperature-Humidity-Checking-Thermometer-Hygrometer/dp/B08BCJNDYQ/ref=sr_1_6
You will need a zigbee controller to integrate and control such as

Thanks for all the suggestions. I don't think any of these solutions really get me where I'm trying to go, and the few that might are cost prohibitive for this application. It's not the end of the world, just would've been nice to have if I'd have found a good solution.

Here's (arguably) the cheapest smartest and most reliable / customizable way:

Take 3 gang sonooff switch, together with a DHT22 temperature sensor, modify the firmware to esphome and attach the dht sensor to the sonoff. Then you configure the fan go on automatically based on humidity and the heater go on based on temperature and for whatever schedule you'd like.


Same place to start if anyone is interested

Are there any off the shelf products that can sense when a garage door lock is locked or open. With a light turning on when it's unlocked. It's a standard sliding lock like this

Can you fit a regular door open sensor there?

I don't think so. Here's another picture from a different angle

I'd have to measure how wide that slot is. Maybe I can use a thin (neodymium) magnet or if possible magnetize the sliding lock itself but I doubt it would be strong enough

Actually a light wouldn't be so feasible. Just being able to check via an app if anything is unlocked would be most realistic

It shouldn't be an issue

Something like this or perhaps better on the other side:
