ThermoPro TP62 Indoor Outdoor Thermometer Wireless, 500ft Range Outside Thermometer with Remote Temperature Sensor, Outdoor Thermometers for Patio with 3.3" Backlit Large Display Thermometer Outdoor

Very easy to see, reliable and accurate.

My 35 year old wired Radio Shack indoor outdoor thermometer finally 'died'. this is the Modern Incarnation of the old unit. Wireless and the inside unit is easy to ready and luckily mounted exactly where the ancient unit served for its duration.

I wasn't sure if I would keep this product but it does work properly albeit I got a defective outdoor sensor my first order. If you find that your indoor and outdoor temperatures don't line up after a few hours of waiting you have a bad unit and don't hesitate to return for a replacement. I was skeptical if my replacement would work properly but it does and everything is now working as it should. I took off one star because I had to return for replacement.

I was surprised how good this unit is after a month's use. The only feature I'm not sure of yet and which could affect future review is battery life, but so far it is much better than the Oregon Science unit it has replaced in that: • the sensor transmits easily from outside one end of the house to the room completely at the other end and through metal siding; the last unit could not do that • While initially I had the sensor indoors right next to the receiving unit and the indoor and outdoor temps differed by a few degrees, I found this was from handling the sensor. The difference went away with time. Outdoors, the sensor sends a temperature which is within one half degree of my expensive and accurate Davis Vantage View weather station. The two devices are in someone different places in the yard, one in sun the other not, but on cloudy, calm days when the readings should be the same, they are • The contrast on the display makes it very easy to read. The display unit is relatively small but the digits completely fill the whole screen and are readable from across the room • The backlight works very well with a tap in the center top of the display • The max-min feature is not explained well in the manual but works this way: you reset the max-min by holding that button for 5 seconds, then there is another button that gives you the choice of showing the max-min temps from the last time you did a reset or the max-min temps within 24 hours of that reset. So if you reset at 11:58 PM and use the 24 hour choice it gives you the max-min since the last 11:58 PM and then starts all over for the next 11:58 PM. It counts 24 hours internally. There is no clock. If you choose the “all time” setting instead of 24 hours, the max-min never resets and you will see the max-min since the last time you reset which could have been a month ago. The unit only operates in one of the max-min modes at a time. If you set it to "all time" you cannot display the 24 hour value. • The only”con” I would register is that there is no beep or other indication that the max-min reset has been successful. You can check to see if the max-min are both the current temp when you do the reset, but a beep would be nice.

Once in a while you stumble on something that truly works great that you never knew you needed, and very inexpensive to boot. We have a greenhouse that we keep vegetable plants throughout the winter, along with summer plants and many variety of spice plants my wife uses to cook. Greenhouse is heated by a couple of electric heaters and a gas unit. We have experimented a lot, and are trying to go all electric this winter. The gas unit works well, however, the pilot light will go off at times for no reason at all. needless to say, walking in the greenhouse and finding it at very cold temps is not good for the plants, hence the switching to electric this winter. I was looking for a newer plain hanging thermostat to supplement an old one that is looking very bad. I stumbled on this one, read about it and the fact that it has a remote sensor to possibly view in the farm house away from the Greenhouse, and only $25, so what the heck. It says it has a 200' range, and the house is maybe 75-100' away. I was truly not expecting much, sounded too good to be true. I installed the batteries, got them synchronized in the Greenhouse, and started counting steps towards the house. my study is upstairs, and our farm house is a barn, built with a lot of metal for its frame. To finish the story, this gadget works perfectly, and I am looking at the temps in the green house, as well as my study. Never knew I needed this gadget and it is now a must have item for the greenhouse. You can buy additional transmitters for different locations as well. I believe it will handle three of them.
