ThermoPro TP65S Cold-Proof Indoor Outdoor Thermometer Wireless, Remote Thermometer Wireless Temperature Monitor of 200FT, Rechargeable Smart Temperature Sensor with Backlit for Home Room Greenhouse

This device works great. The display is easy to read and can be illuminated if necessary. The outdoor sensor can be charged using the included USB cord. The sensor will hold a charge for approximately 30 days. The indoor display unit is battery powered (two AA). The device comes with a set of batteries included. Our indoor temperature, as measured by device is exactly the same as our thermostat. The outdoor temperature is typically within one degree of the temperature given on a weather app. Very satisfied with this purchase and would recommend it to family and friends.

Works well, and easy to set up. only thing is the light button is next to the sync button and in the dark I sometimes hit the sync by mistake and it cancels out the remote.

The display is great!Easy to read, large digits. Able to pair with outdoor thermometer easily. I especially like monitoring humidity inside the house.However, there is a large swing in accurate readings, vs. weather stations and apps - 2 to 8 degrees difference, no matter sun, shade, or at night. I will be calling customer service for possible remedies.

I bought two of these & both of the outdoor units are dead already. The indoor portion still works fine but that's not the reason I purchased something like this. They were both installed on my covered front porch away from any inclement weather & out of direct sunlight. In the outdoor units there is a rechargeable battery which I believe is the failure of both units. One of them does absolutely nothing when plugged in to charge & the other says it's charged & then will only last about 30 seconds before dying. Buy something with replaceable batteries!

I've had a couple of Thermo-Pro indoor-outdoor thermometers, and currently own two. (One helps me keep track of the temperature and humidity in my unheated basement crawl space.)I've had both the battery models and the kind that recharge via USB. The battery models seem to consume batteries at an unusual rate (for both the display and the remote), and then they just seem to die unexpectedly. So I have moved to the USB-chargeable ones. (The display always needs a battery.) These seem to last a long time, and don't suck up batteries. Also, the face is larger and easier to read.So I recommend getting the Thermo-Pro model where the remote can be recharged via USB cable.

After a year of use, the sensor stopped reading. Even though it is supposed to show a low battery reading on the base unit and didn’t, I decided to recharge the sensor. After attaching it to it’s USB charge cable, it is supposed to change from a red signal light to green when charged (4 hours.) After 24 hours waiting, it is still red and will still not sync with the base unit. I bought this style because it use rechargeable lithium battery technology instead of battery replacement. I expect more from Thermo Pro. Attempts to contact customer service take weeks to get a response.

Great product, just don't expect it to align with real temperatures accurately. If it's say, 58 degrees, you can be sure of its accuracy from 53 - 63 degrees. I found it to be accurate in the morning and night hours to the actual degree, only to vary somewhat over time. But this is what online thermometers say is good. I'm happy with this IN/OUT thermometer. Like this AM, my Thermpro thermometer was 58 and online measures agreed, but since writing this review ThermPro reading went to 59 degrees and all online that I use are 61 degrees.I use a standard, analog thermometer as a backup. It says 60 degrees. Yeah, I'm Happy.

I use this and set it on my bed night table at night so I can check to make sure my birds are nice and comfy when it is rather cold outside. It is very accurate and I can depend on the inside temp of the bird houses to be 9 degrees wormer than it is outside. This way I know how many red heat lights to turn on right before nightfall. Saves on money on electric use to know whether to use 1, 2 or 3 heat light. I also use rechargeable batteries in receiver and thermo reader so I save money with chargeable. This product is a win win.
