Three products all in same room with different readings. I am convinced Wyze can only make a good camera. Everything else is china junk.

Um, since none of them agree why are you concluding the Wyze is the worst of them?
All three are Wyze.

I think the sensors are really stupid. Also it messed up the last FW 1.2.5.
Wyse, have an option for FW with and without sensors. Revert back to 1.2.1. It worked very good until you messed up with stupid sensors. Thinking on returning all 3 thermostats I have to WYSE and demand a refund. This is really bad and lots of people will have damaged heating/cooling systems.

To be fair, the thermostat on the wall is designed to be in a central point of the house to properly gauge temperature. The remote sensors there are also being offset by body heat and not attached to the wall. I’ve found those sensors to be very sensitive when held that their temperature rises pretty quickly. This lines up with the one in-hand being warmer, and the ones at the fingertips cooler.

Here you go not in hand and same place for 24 hours. 3 different temps lol. On top of that brand new thermostat and brand new sensor are not pairing. Old sensor paired fine for a year however not any longer. FYI they are all in the same place because I was trying to pair them but they wont. They are junk to me now. Ready for the landfill. If anyone wants to buy off me I can put on ebay.

Ideally, all 3 should be in the same location.
Also, with digital readouts you always have a plus or minus 1 count possible error. Since there are no decimal place digits, that means the whole degree increment has a possible error of + or - 1 degree, no matter how accurate the sensor is. Thus, the 73 and 71 readings may just be two different ways to represent 72.
So neither the old or new sensor is pairing now? You might want to contact support on that!

I did. They send me a new thermostat and sensor. Still does not pair. I sent them so many logs. Clueless.

The Wyze color bulbs (13w) are awesome. The CRI is much better than the Novastrella and Sengled bulbs i have. That said…
Its notmal for temperatures in the same room to vary by 5 degrees F or more. Depends on where its located, if the air is static or a constant flow of movement, the wall, nearby appliances, etc. They look appropriate to me. Like someone else said, the one in your hand is warmer from body heat. The wall thermostat is likely picking uo some heat radiating from the wall. If you really want to know, buy a scientific thermometer and go through proper calibration, then place it around the room and let it settle.

The distance of 6 inches could be a degree difference. Thermodynamics and such. But yes, basically all temp sensors take readings in Celsius. Then it converts to F if thats what you want. The sensitivity is high enough for it to give an accurate F reading tho. Depending on the coding of the unit, it may round up or down and may not follow our standard of rounding down from 1-4, and up for 5-9. And even then, 71.4 and 71.5 would give a degree difference with no decimal places. Even tho its only a 10th degree difference. Youd be surprised just how much variance there is in the temperature in a single room if you were able to see the air with a thermal cam. One study had tons of sensors placed in a room in all 3 dimensions. It read the temp, humidity, and air flow. It could detect the slightest air movement but the sensors are not directional. But thats why they used so many. You could figure it out based on cluster readings. Then the data was recorded and sent to a central computer which created a 3d visualization of the air temp and air flow. Obviously the sensors themselves altered the readings from what it would be without them, because resistance. But it was pretty cool.

These photos prove nothing. Like others said, you’re not even putting them in the same location. Apples to oranges. Do better!
I provided two pictures that all in the same location. Literally inches apart.

I’d be the last person to praise the quality of Wyze products, but you should not expect precision, nor accuracy, from cheap, commodity temperature gauges. One degree difference is nothing to complain about. Not even 2 or 3 degrees difference. Then there is the other side of the story: what critical life decisions are you going to make based on a one degree F temperature difference?

Differences between non-scientific temp devices of +/- 3F are considered standard. None of the devices (thermostat / room sensors) are expected to provide lab grade readings.

But also a cheap non-scientific temp devices does not randomly shows different temps. Yes is garbage.

I’m always baffled at how people “devolve” so quickly when talking about this stuff… immediately going to the term “garbage, trash, junk”… “never going to buy again” etc. etc.
@ultra1genius Said it best… exactly what is “really” affected by these degree differences? It’s not ruining furnaces, and it’s not making furnaces run crazy. I have 3 temp sensors and don’t see these degrees of error to be something that matters. They sit in 3 different places… I setup the degree fluctuation and I setup if they are used for the Home or Sleep profile… They seem to average the temperature of the house according to the active room and adjust when I go to the other room and it’s colder.
That’s it. They seem to be working pretty well.
There is enough venom on the internet. No reason to spew more of it when talking about the simple degree differences in room sensors. There are battles to fight with product quality… this is not one of those battles.

I DO NOT have sensors, and I DO NOT want any. Let me have a FW WITHOUT sensors. And YES is ruining my AC by INACURRATE temperature readings by the THERMOSTAT itself. It cycle the AC every 2 to 3 minutes because the TEMP jumps up by 2 or 3 degrees. This is not VENOM is a statement that a VERY GOOD product (T-Stat) got ruined by the stupid sensors and 1.2.5 FW. It worked perfectly before on 1.2.1. So yes is GARBAGE now for me.
Ha. Imagine having sensor that is 3 degrees off in a babies room. 62 degrees vs 65 in the winter is pretty brutal.

I guarantee you that within that room alone there is a variance of at least 3 degrees between coldest and warmest area of the room. Wider if there’s stagnant air.
