The wireless thermometer and remote sensor let you easily monitor the temperature of 2 spaces in and around your RV, camper, or home. The thermometer can be used either inside or outside. This means you can make sure your perishables aren't thawing out in your garage freezer, and you can make sure that your pipes or tanks don't freeze during a cold night. The monitor and remote sensor are also very easy to wirelessly pair up, requiring no hardwiring or hard work.

TempMinder Wireless Thermometer Remote Sensor

The remote sensor reads the temperature of an area and wirelessly sends it to the LCD screen on the monitor. The screen then displays the temperature of both the monitor's location (labeled indoor) and the sensors location (labeled outdoor) at the same time. These temperature readings can either be shown in degrees F or degrees C. And if there are more than 2 areas that you wish to monitor, you can add up to 2 additional remote sensors (RS-TX - sold separately).

TempMinder Wireless Thermometer Built-In Clock

This thermometer also has a built-in digital clock, which provides you with 12-hour and 24-hour clock options.

Easy and Quick Setup

The thermometer and sensor are easy and quick to setup. 2 AA batteries and 2 AAA batteries (not included) are required. For the best performance, use alkaline or lithium batteries. Once the batteries have been installed, the temperature will then appear, and you can use the downward arrow key to switch between degrees F and degrees C. If you are adding additional sensors, repeat the same process, and use the upward arrow key to navigate between channels.

When setting the sensor in place, make sure you choose an area that's not in direct sunlight or vulnerable to the elements. You can either set the sensor down on a table or other flat surface or you can use hardware (not included) and the slot on the back to hang it on a wall.

Video Transcript for Review of TempMinder RV Weather Stations - Digital Thermometer - TM22259VP

Ellen: Hey everyone. I'm Ellen 00:00:02 Here at etrailer.com today we're taking a quick look at the TempMinder RV wireless thermometer. This is also going to have a clock so you can keep track of the time as well as the temperature inside and outside your RV or really anywhere that you'd want to have your two pieces here. So we'll have our monitor, which is going to be this piece here obviously, and then also our remote so we can place this somewhere else so we can monitor the temperature in a different location. So it's handy for putting in your freezer or your refrigerator to make sure that the temperature stays nice and cold in there or maybe putting it in the lower compartment on your RV to make sure that your pipes aren't going to freeze. Maybe putting it somewhere where your pet is, you can make sure that they're not getting too hot or too cold, whatever the case might be.So we'll be able to keep track of both temperatures.

Now the way I got the temperatures to look different here is I just held this in my hand to bring that temperature up so that little light will kind of flash every so often letting you know that it's still sensing and still working, but these two have been sitting in more or less the same room. So we'll just wanted to show you that there is a difference in the temperature and it does actually show you the difference. The top number is going to be our remote temperature and then the bottom one is going to be the temperature that the sensor or the monitor actually senses. So it says outdoor and indoor and that just means the outdoors is going to be the remote, indoors going to be the monitor.To make any adjustments to the clock you'll just need to use the set button on the back and adjust the temperature as needed. You can change that clock to read in 24 hour option as well or military time if you prefer.

And this works for temperature ranges between negative 22 degrees Fahrenheit up to 158 degrees Fahrenheit or negative 30 Celsius up to 70 Celsius.The distance that you can move the remote and it'll still work is going to be up to 165 feet and if you want to, you can also use a couple other sensors with this so you can use up to three if you want to have additional remotes for your tracker here. You can just cycle through those. So we'll have a couple other slots so we can still read from.That's pretty much all there is to it, for our TempMinder. I'm going to give you a couple measurements just so you can have a reference on the size. It's about three inches wide by about four inches tall.

Does lean back a little bit so it might be a little bit shorter than that. And then with the stand it's about an inch and a half deep. Our remote sensor measures about four and a quarter inch long by about an inch and five eighths. And then it's just about seven eighths of an inch thick. It does not come with the batteries.

You will need to provide two double A's for the sensor and then also to triple A's for the monitor.You can Mount this to the wall if you prefer. There's a little spot there if you want to hang it on a nail or something like that, or a hook, and it does have a one year warranty.That's it for our look at the TempMinder, RV wireless thermometer.

Very good looking and easy to set up. didn't come with mounting screws. I used Velcro to hold them in place. 564328

Had a short in my old inlet. This inlet much more water resistant than what I had and what I found in a local shop (which I later returned). I had some questions about the inlet hole diameter and asked a question on etrailer. got a response in the next business day. shipped my order 12 hours after received on a Sunday. Every interaction with etrailer, website, question and answer, shipping notification and follow up has been outstanding. Customer Service is fabulous. 714844

  • Troubleshooting Dashes on Display of TempMinder Thermometer # TM22259VP for Outside Temp
    If the display for your TempMinder Digital Thermometer with Clock # TM22259VP frequently shows dash marks for the outside temperature then there's likely some interference going on between it and the transmitter. The most common cause for this is radio interference from a nearby device. This can be awfully difficult to track down since we can't see the signals, so the best way to resolve it is to simply move the display and transmitter to a different location. Moving them even a couple...
