I'm looking for a wifi enabled t-stat that has a low set point (under 40 degrees F) for my garage. Any suggestions?

WiFi Thermostat with low set temp?

Honeywell makes several, Models CT50 through CT55.. Menards sells one of them advertised as specifically for garages and outbuildings. They aren’t WiFi, though
Make sure your heat exchanger is suitable for low temperature maintenance type of operation, though.
Many low priced hanging heater installation instructions specifically warn the user that the unit is not suitable for freeze protection and the minimum set point is 50 degrees. Low temperature operation allows corrosion to damage the heat exchanger.
Low temperature warehouse type heaters have higher cost stainless steel heat exchangers.
Even boilers aren’t immune. My friend’s Trane boiler died at about ten years. He kept his shop below 50 degrees through southern Wisconsin winters. His hvac installer opined that corrosion from low temperature induced corrosion was the culprit.

Thanks. If I get 10 years out of a $400 unit heater I'll be pleased.
Wifi is required for this purpose.

Just checked my Ecobee 3 and the low setpoint is 7C (44 F). Close but no cigar. But its wifi, has a great phone app for access (the app is basically the same interface as the t-stat), and there are low / high temp alerts you can set (down to almost freezing) that will notify you if they are tripped. They also have some great analytics tools online where you can access your t-stat data. Zacolley has a recent post in the heating forum with some Ecobee screenshots.
Probably similar features as other wifi stats, but I have been happy with this one.

I had this same problem this is the ONLY one I found with low set temps. No big company wants the responsibly of having a thermostat that allows set point that close to freezing. I will have to check but I think mine goes to 35. It works great

Be careful with Radio Thermostat....I killed 2 of them because my HVAC unit was putting out too high a voltage (by 1.5 volts)....They replaced them for no charge, but asked I run a separate power supply to them.....I replaced them with a different brand of connected t-stat and never had another problem.....
This was several years ago so they may have 'fixed' any issues with over/under voltage......
I have both Nest and Ecobee wifi thermostats in my home (7 Nests and 2 Ecobees) for the different zones.
They both have economy settings when you are or aren't home and minimum temperature settings.
The Nest is 40 degrees F.
Because I can control them via the WWW and my smartphone... I can manually shut down the heating per thermostat or just let the thermostat's minimum temperature default take over.

Thanks all...I decided to just grab another Honeywell wifi (basic). I have one in my daughter's room and since I'm familiar with the app and the unit and found one brand new locally for $45 I jumped on it. They only go to 40 degrees, but that'll work as I can also shut the heat off via the app. Good enough for me.
