Just sent in pictures of my smart thermostats. Honeywell and a Warmup 4iE smart thermostat of which I have 2.

Hi @mike.s,
Does Wyze thermostat have a “C” Wire? This is required in most thermostat setups these days in USA?
Glad to hear progress is being made @mike.s! I recently moved & replaced the thermostat with a Nest, so I uploaded a picture of both. I look forward to switching to the Wyze thermostat!

Wyze Product Engineering - No one has yet come out with a decent quality or reasonably priced smart thermostat to control a 120v/240v electric baseboard heater. Honeywell still hasn’t offered one. The only one that is on the market is: https://getmysa.com/ I think you guys could do a much better job at this and at a lower price. Don’t confuse this for something like Nest or Ecobee. It needs to be a wall mounted switch capable of modulating the 120/240v load to achieve a scheduled temperature setting. Also needs capability for full OFF.

This one will run baseboard heat from Warmup. I have two of their thermostats running under carpet heat and under tile heat but I am looking at getting another one for the baseboard heat in my wife’s yoga room. They are a great company I have had excellent customer service from them in the thermostat is top notch you can do scheduling you can do vacation mode and like you said you can completely shut it off if you want to

You can install a relay like the one pictured. I was able to use this relay which enables me to run the heater in my garage from anywhere, as well as verify I turned it all the way off. It works on 220v heaters and supplies the needed 24v to power a smart thermostat. I would much rather have a wyze thermostat though, keep everything in the family

Looks very similar to the 12v to 5v downconverters that I just bought. I replaced my old CCTV cameras with Wyze V2s. and use the existing power cables so I didn’t have to run new power.

So you still have a smart thermostat though is that correct this just allows you to use it with the baseboard heat?

Yes, a smart thermostat, with a 220v baseboard or fan forced heater up to 5,000 watts I believe. Mine is 4800 watts and I have had no problems.

Sorry to hear that Wyze is trying to go head to head competing with Ecobee and Nest. Love my Ecobees and would not consider switching. Already too heavily invested. I had hoped Wyze would see the advantage in going after an underserved market targeting electric baseboards, thermal flooring etc, which many homes have. Typically each unit needs its own thermostat room by room, hence it needs to come in at a price point under $80 per unit. Nearly all smart thermostats are designed for centralized/zoned HVAC where one can justify spending $200/unit. You already make smart plugs handling high voltage. It’s not that much of a stretch to add temperature monitoring to that and enable that to control the baseboard heater via a relay to turn the unit full on until the desired temp is reached, then cycle as needed to maintain the temp. The only interface needed on the switch itself would be akin to a dimmer control calibrated to temperature rather than lumens, plus display current temp and temp setting. Keep it simple stupid (KISS). All other features such as scheduling and control timers can be in the app.

Thanks for the suggestion. Warmups are nice units, are not suitable for my purpose as:
- They are only for 230v in UK. I need 120v for US
- Cost of Warmups are too high. Each baseboard unit needs its own thermostat. ROI to install means it has to be under $100USD per unit, preferably closer to $75 each.
For them to get a thermostat out this year like they said during the ask me anything they were either going to “borrow” a thermostat design from another company like they have the cameras and stuff like that or they’re not gonna get it in this year. Just a couple weeks ago they asked for pictures of wiring. Which is kind of concerning because they should know the different kind of wiring the different thermostats have. Makes you wonder if they’re getting into an area that is foreign to them.

I just installed my fourth smart Wi-Fi thermostat. Wyze you’re taking too long.

Which brand and model?

Warm up 4 IiE smart thermostat. You can even use it to run baseboard heat. I’ve got two installed and might be buying a third. One runs my under carpet heat one runs the key under my tile floor in the bathroom and I might buy a third to run the baseboard heat in my wife’s yoga room because I am tired of waiting on Wyze. I doubt that the one that they develop will be able to run baseboard heat anyway

Hi @mike.s,
Just uploaded a better photo of my Honeywell Wifi Thermostat wiring. Hope this helps. This is a USA setup.
I have Honeywell too. Lol

I’m looking for two new smart thermostats to replace my Schneider Electric Wiser Thermostats. Would be very interested to see which design Wyze goes with.

I want to have it already! My current Honeywell WIFI Thermostat is 6 years old and has started to turn off intermittently. Forcing me to take it off the wall for a few minutes for it to reboot.
