Thermostat wiring question to 24v

I want to use this to only monitor temp in my garage. I have a 24v Power Supply. Do i wire it to the R and C to power it up? I am not hooking to a furnace or a/c.

Yes, Rc and C are the 24V power lines for the wyze thermostat. Although I’m not sure it will let you set it up without an output device, you might need to tell it that a W wire is connected as well to get it through configuration.

Wouldn’t a climate sensor do that? A lot cheaper too. Or do you have an extra Wyze Thermostat that you have no other use for?

I have a spare
