Hey, What is this 5 degree issue exactly, and has Wyze corrected it? I bought a thermostat a while back but haven’t gotten around to installing yet. Not sure I want to depending on this issue…
It seems to be fixed as of quite a while ago. I haven’t had any real issues for at least 6 months.

And are we getting close to the 3-1 thermostat remote sensor being ready? Is there more info about how it will work and what its capabilities are?
Fantastic, thanks!
I’m hoping this finds someone with HVAC knowledge. I went to install my Wyze thermostat and found my current thermostat only has 2 wires connected the Red to an R port and a white wire to the C port. And… those are the only available ports… (see photo). The back of the my thermostat there are two prongs which connect with the (pictured) ports.
Walking through Wyze installation, when I tell it those are the two connections, it tells me I don’t have heating and cooling!! (I do). But, I also have a heat pump. I don’t think I have enough wires connected for a heat pump to function properly. I’ve only had one heat pump before about 30 years ago, but I seem to recall it having more wires connected. Inside the wall, there’s a green wire and a blue wire bundled together.
So my number one question to HVAC folks is, do I have an existing thermostat wired properly for heat pump?
Thanks oh Wise Wyzer Wizards…
I would have a hvac/heating and cooling person out to check your system as there should be more wires involved in your system, unless there is an second thermostat in your home.

There is a second thermostat, but it controls another totally separate downstairs HVAC. My upstairs system works - heats and cools - but I’m trying to recall if I’ve ever seen it running in heat mode without ‘auxiliary’ heat on.
HVAC pro here- I must admit I’m not 100% familiar with your thermostat based only upon the picture of the wires. I SUSPECT what you have is a wireless tstat (not necessarily wifi) that only requires power to it’s location to operate. These communicate wirelessly to a receiver usually close to or inside the air handler. You’ll find all the other control wiring connected to it (R,G,Y,W,O/B,etc). These are usually used when there are not enough wires in the run to the existing stat location to operate heat pump or multi-staged equipment and pulling a new stat wire is difficult.
If you look on the back of your tstat there’s usually a model number. Google it looking for the INSTALLATION instructions (not the user guide) and it’ll have the wiring diagram.
Hi, I suspect you’re spot on. I wondered if that was at all possible. I did Google the thermostat - thx9421r5021ww - and found that the connection to the outdoor thermometer is wireless, so it does definitely have that capability. In which case the Wyze thermostat isn’t going to work for me. I already have a Honeywell tstat downstairs so already running that app on my phone. I guess I’ll spend the $60 to get the Gateway - yet another hub, oh brother.
Thanks so
Hey, quick question, how common would you say it is to have a situation like mine, that is a need to part of the thermostat control elsewhere (not with the accessible wall tstat)? I haven’t encountered it before… that I know of… But I can imagine that there are lots of cases like mine where a heat pump or otherwise more complex system was added to an older home. (Mine was built in the 1980’s). Especially as common as switching over to heat pumps has become in the American South. I’m asking because if it’s frequent enough, say 20% of homes, I could see Wishlisting Wyze to add necessary equipment/capability at some point. Obviously not very soon, but some day.
It is still the minority for sure. All the major equipment manufacturers already have their own proprietary protocol communicating systems requiring only 2-4 wires to operate.
The situation you have starts way back before digital stats. “Legacy” or analog wiring only required 1 leg (R) of the 24VAC control power run to the stat. The mechanical stat did the rest with a mercury switch on a bimetal spring coil for the temp/condenser control and the user switching between heat, cool, and fan on/off. Many older homes were only wired with 4 strand bundles to the stat.
Fast-forward to digital stats. They require either both legs of the 24V or batteries to operate the electronics. Hence the reason some stats can use either in case there’s no common wire.
Now add a heat pump, there’s another wire needed. 2 stage cooling? Add another wire. Dehumidification? Add another wire. Outdoor temp? Add another wire or 2…
Most of your entry level systems still use legacy wiring. Communicating systems have their own inherent issues of trying to run data across non shielded 20 gauge wiring and the fact that each manufacturer has their own proprietary protocol, there’s no aftermarket thermostats for any of them. They locked that down since day 1.
There are several companies already making the wireless legacy transmitter/receiver setups that you have. Seeing as how it’s not a huge market and it’s already got several players, I don’t know that this would be a product for the Wyze family. Return on investment and all…
Exactly what I suspected. It sounds like my next question was answered as well. Which would’ve been, is it possible for a a competitor like Wyze (or Nest or whoever) to communicate with that interior controller (not sure what it’s called) inside the air handler or wherever.
I get these neat little reports of monthly stats from Honeywell for my WiFi thermostat. I’m curious if the Wyze thermostat gives users anything similar.

That doesn’t really look like it provides comparative data…
RE; Wyze Thermostat GEN 2. Didn’t know where to post this. Looking forward to next gen thermostat that includes humidity levels. Have Honeywell basic ones now. Really want the humidity level, control via app and motion.
One suggestion (probably too late to request): Would Wyze build a horizontal thermostat vs. vertical? Simple reason… I really don’t want to have to remove old thermostat, patch and paint, then install new one. If it were horizontal layout, then wouldn’t have to paint.

any updates on a software update so the thermostat can control whole house humidifier AND automatically adjust the inside humidity based on outside temp? I was hoping that, by this winter WYZE would have done that but nope…which sucks

I will be hooking mine up in a few weeks. My system has a Whole House humidifier attached to it, so I will be hooking that up as well. From what I understand, it is a single wire connection to the T-Stat and is supported.
I currently have an EcoBee which is what the Humidifier is connected to. I will be adding it to the Wyze T-Stat and will share my results when done.
Wyze recently surveyed users on future insights reporting. One day they may release an update to add useful info to the Insights screen. Currently it’s not very insightful.
Hooked mine up and it works for controlling my Home Humidifier. The only catch was when it asked the question. It asked what features the Humidifier had - Heat / Fan. you could check one or both. I checked the fan as it only has a fan and not a heater. When I went to my HVAC system the Humidifier was on because the fan was on. I realized it was asking how to control it. I set up the T-Stat again and then selected Heat. All is good. There is a min and max humidity setting which will keep your home at the humidity level you desire.
