I have updated my article to include more detailed setup instructions. Please let me know if I should change anything. I hope this helps everyone.

Acole did you need to select other?
I would normally pick forced air.
Just wondering, Iāll be installing the same as you.
Thank you.
Yes, you can select other or even radiator. The issue with forced air is that it always turns the fan on, so the A/C fan comes on when the heat comes on. Most RV furnaces have their own fans that they control themselves.
Acole, one last question I promise, I leave my rv powered and on during the shoulder months, but use the exiting off switch on the t stat to prevent the heat from running while away, does the Wyze stat have that feature, or do you know how low you can set it for heat like 40 degrees to prevent me from using propane while away?
Thank you,
Jamie
Jamie,
The lowest it goes is 50. You are able to turn it off so the heat or ac doesnāt come on. The unit itself will still draw a small amount of power but shouldnāt matter if you are plugged in or even have a small solar trickle charger. The nice thing about it is if you have internet, I keep a small mobile hotspot in mine, you can monitor the temp and adjust the heater settings remotely.
Feel free to ask as many questions as you want.
Sorry for the very late reply. Member acole tried using the T-stat out of the box and it worked fine. Just us either the Radiator or the Other setting while programming(I didnāt at first). So far it is working fine.
Iāve used ZEN WiFI stats which run on AA batts and Honeywell standard WiFi stats using a 24v transformer in my RVās. Both work fine.
This would be a great add on to your product line. We rverās are always looking for a dependable 12v smart thermostat and there are very few on the market. You could find it to be a cash cow if you created it. I know a lot of people would buy it.
The wyze tstat already in the market works fine.
Will it function on the 12v supplied by the camper ?
We found this one after searching hoping someone else would come up with one. It works great and we love being able to monitor the temperature while not at the camper!
Surprisingly, YES.
See above posts and links back Member acole
12vdc is āin a wayā half of 24vac so it works only using the positive half of the sign wave.
This is not 100% accurate but good enough to be able to use the Wyze T-Stat which is a whole lot cheaper than other smart Tstats designed for RVs. The one we are using is hooked to both the electric roof mount AC and the Propane Heater. See my last post about which setting to use so both fans donāt run at the same time. We have another roof mount AC in the bedroom that is still using the old Tstat shown above. Will be replacing with any Wyze Tstat in the near future.
Hey guys. Really glad I found this thread. I installed a Wyze thermostat today in the bedroom of our 40ft Keystone Avalanche 5th wheel following the provided instructions from Cole Family Adventures website.
I have a Coleman Mach 3.0 AC unit in the bedroom and bummer thing is the Fan wonāt kick on but the compressor kicks on. I tried high (Green wire) and low (gray wire) in the G socket on the thermostat base and nothing. Confirmed AC unit works fine switching back to the OEM Coleman thermostat. Our living room AC is tied into the propane furnace being that setup is a bit different and Iāll try the Wyze thermostat on that one laterā¦ but really want to get this working in the bedroom! Any ideas?
You might be able to select furnace for your use case instead of other/radiator. Out of curiosity, does the fan come on if you switch the fan mode to on instead of auto?
I didnāt see any where in the app to select fan to ON or auto or on the thermostat screen itself. I did do the update. Also, when setting up the thermostat (because the bedroom AC doesnāt have a furnace) I selected āNO heat/pumpā.
On the thermostat you should be able to click it and the scroll over to fan. On your phone if you swipe the white bar on the bottom up then you should see an option for fan there too.
Oh snap thanks for the reply! Iām gonna go plug it back in and play with it some more. I reply back with my findings,
Got caught up yesterday with other things sorry for the delay. But got the Wyze thermostat back hooked up in the bedroom, could not see anything for Fan controls on the app or thermostat itself. So I reset it and said it had āHeat pumpā and skipped thru all the wiring prompts. I now see fan controls in the app and thermostat screen but it still doesnāt make the fan come on 
Edit: found out when selecting FAN to ON the Compressor kicks on while HVAC is set to OFF and still no Fan kicking on, Iām confused. Confirmed at the AC unit control board that the thermostat wires are correct per instructions. (I.E. wires not labeled incorrectly)
2nd Edit; I just did some voltage readings at the OEM Coleman thermostat understanding how the system works a bit better. Iām a noob when it comes to HVAC electrical systems. I see now that the thermostat is just a bunch of power relays telling which wire to get voltage when it instructs. Yellow wire (compressor) gets 12v when turned on and so does the green wire (fan) on the Coleman thermostatā¦ Vices versus with the gray wire (low speed fan) when selectedā¦ so Iām either going to try and do some voltage checks at the Wyze thermostat seeing if the G socket is putting out 12v or just tie the yellow and green wire together so the fan is always on when the compressor is on but Iām unsure of the consequences (if any) by doing this.
EDIT #3!!
I got it working!!! I donāt know exactly what made it changeā¦ but I was checking voltage at the green wire coming out of the Wyze Thermostat finding that it was only producing a constant 3.76vDC with the fan turned ON or OFF. Verified the yellow wire was producing 12vDC when the fan was ON and no voltage when selected OFF same for the HVAC setting, on or off so the fan control and HVAC control weāre only going to the yellow wireā¦
so I reset the thermostat and deleted it from the app. Re-configured the thermostat from factory settings via the app telling the app it doesnāt have a Heat Pump (again), selected the wires accordingly to their letter codes and BOOM! The app was showing Fan Control settings (without heat pump, not like the first time I set it up and app or thermostat didnāt have Fan setting menu) and green wire was producing 12vDV when Fan selected to ON and no voltage when selected to OFF! Yellow wire was finally separated from the Fan Controls and HVAC settings controlled the compressor individually. Iām satisfied now gotta get this thing mounted and start fine tuning the settings!
Alright guys Iām back at it again. Finally got myself another Wyze thermostat for our RV. Main difference is the boxing is different and now saying the voltage rating is for 24VAC where as the Pre-Order box (from my first one) says 24V.
I ordered this thru Home Depot last night and surprisingly it showed up the this morning in a Home Depot bag for $9 next day shipping!
The first Wyze thermostat I got and successfully am using for months now in our 5th wheel bedroom has been working great with the Coleman Mac AC,
So I figured let me pop off my original one (that works) and pop on the new one and see if it turns on, and nope the new one does not turn on.
Does any one know if they changed the voltage requirements in the new Off-The-Shelf models versus the Pre-Order models? Same model code and allā¦
Iām going to mess with it later in the living room AC system see if I can get it to turn on, but simply removing the one that works now in the bedroom and popping this new one on, it does not turn on. Pop the old one back in and powers right up.
It should still work. Since the power gets rectified internally to dc for the mcu. Technically the original was for VAC since that is what most home systems use.
