Honeywell TM005X Wireless Indoor/Outdoor Thermo-Hygrometer

As I live is a very humid part of the country, the TM005X is very useful product as I need to control the humidity in my home and garage. While I find the product useful, I have not found Honeywell TM005X to measure humidity very accurate. Watching the reading of the two remote sensors, the Honeywell TS33C, and the main unit in the same spot, none read the same and none agree with two other Acurite hydrometers that do read consistently the same. The Honeywell readings very over a range of 5 percent. I called and asked the manufacturer whether I had defective units and they said no, their TM005X and TS33C products readings will vary. I think they should be more accurate. The temperature readings all agree.

This review is for Honeywell wireless I/O thermometer/hygrometer TM005X. We've had our unit up and running for about a month now. Other than a loss of signal during the initial setup, it has been working flawlessly since. Our receiver and transmitter are seperated by one wall, and are approximately 40 feet apart. I bought this unit because it is one of the few wireless models that have a low-ish temperature range (-38F). We live in Northern Minnesota so it is not uncommon to have a few days each winter that are colder than that (-50F). Likes: Large, attractive and easy to ready display. The option to monitor multiple transmitters. Dislikes: Transmitter range only goes down to -38F. Receiver does not display indoor and outdoor temperatures at the same time. You have to either toggle through the channels manually, or set the unit to auto-cycle from one channel to the next. It would be nice to have the option to display the indoor and one remote channel temperatures one the same screen, with the humidity readings made either smaller or on different screens.

I've had half a dozen various brands of indoor/outdoor wireless temperature sensors... and they were all junk. This is the first that seems to be of decent quality and well worth the cost. I bought an additional remote sensor so I can monitor temp & humidity of 4 locations: wherever the monitor is, basement, nursery, & and outside. Likes: quite accurate (within a few degrees), humidity reading, min/max data, big display, simply easy controls, ability to monitor 3 additional locations wirelessly. Wish list: ability to calibrate all sensors, light option on monitor, ability to add additional sensors (max is 3).

I bought this to keep track of conditions in the baby's room. After buying a color changing egg, I got tired of getting up and peeking into the room to see what the temp was. Then I bought a wireless color changing egg which interfered with the monitor. I finally bought this one and am pleased. I should've bought this first. There is no interference and the remote unit is small, plain and unobtrusive which means that the baby doesn't try to play with it all the time if it winds up in reach. Set up was super easy. The fact that you can add two more remote units is nice. The only thing that it is lacking is a backlight on the main unit. Honeywell, if you read this, add a backlight and sell it at baby stores and you'll sell many more.

I bought this product for my customer. We have just started retrofit foaming houses. The critical issue is making sure that the humidity in the attic is being controlled properly after the foam has been installed. All of the bathroom exhaust fans must be filtered out of the attic to a soffit vent as well as the kitchen exhaust. In order for the customer to monitor their own attic we have started purchasing this product as part of the health and safety protocol. Happy to report that this product works excellent. I love the big display that is easy to see across the room.

I got this thermometer/hygrometer so I could monitor humidity in my home after installing a geothermal heat pump with inline steam humidifier. What I like about this unitis that it has an extra sensor which I put outside so I can see the difference. It's very easy to use, and seems to be quite accurate.

The product looks very nice and has a large display. I wanted a large digital hygrometer. That was the primary reason I bought it. I think it works well. The termperature read out is about 1 degree higher than other digital termperature gauges that I have. I bought two of these and the temperature difference seems to be the same in both locations so I assume it is part of the design. Either it is more accurate than others I have or it is off by about 1.2 degrees on the high side. Don't know which, but I think it is about 1.2 degrees on the high side. So for instance, when this items reads 76 degress, my other digital temperature gauge reads 74.8 degrees. But, overall, I like it and for the price it seems very well made. Even has a remote sensor. Not sure how accurate the hygrometer is, but it's relative humidity so it is really the changes I am interested in and it works very nicely.

I purchased two of these for an expansion to my data center. They are sensitive and the remotes are helpful for operations staff to stay on top of any temperature of humidity fluctuations. Good product.

Excellent local thermometer and has up to three remotes possible. Only got one remote with original but will purchase two more.

This item works very well for what intent of use is. It measures the temperature and humidity fairly accurately. It was an easy setup as well.
