## Overview

The La Crosse Technology TX37U-IT is a compact, wireless temperature sensor transmitting accurate outdoor temperature data over a robust 915 MHz frequency up to 330 feet. Designed for seamless integration with La Crosse weather systems, it measures temperatures from -31.9°F to 139°F and operates on 2 AA batteries, making it an essential tool for millennial professionals who demand reliable, real-time weather insights to optimize their daily routines.

## Description

Monitor outdoor weather conditions from multiple locations of a yard by adding an extra wireless temperature sensor to a household La Crosse Technology weather system. The TX37U-IT wireless sensor transmits outdoor temperature readings to a base unit to enable users to plan appropriately for brisk or hot weather. With any La Crosse 915 MHz weather receivers, the sensor communicates from a distance of up to 330 feet. Outdoor temperature measurement capabilities range from –31.9 to +139 degrees F. To ensure the most accurate readings, install the sensor out of direct rain and sunlight. NOTE: Below is the proper troubleshooting 1. Start with a complete restart using new alkaline batteries dated 2024 or newer And have the indoor station and outdoor remote 3 to 5 feet apart. 2. Batteries should be out of both units for 10 minutes. 3. Place the batteries into the outdoor remote first then into the indoor station. (All outdoor remotes must be started before the indoor station) 4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES. In this time the display and sensor will start to talk to each other and the display will show both the indoor temperature and an outdoor temperature. If the station does not display both temperatures after the 10 minutes please retry the setup as stated above. After both indoor and outdoor temperatures are displayed for 10 minutes you can place your sensor outdoors and set your time. The remote sensor should be placed in a dry, shaded area. The transmitter should not be more than 330 feet / 100 meters. Note – Metal siding, stucco, and some types of glass can reduce signal range. It is possible to receive a signal through these materials, however maximum range will much less due to their tendency to absorb or reflect a much larger portion of the transmitter’s signal.

Review: Make sure you don't have old transmitters laying around trying to compete with each other! This item works! - It works! This is sort of a long story, so lets begin at the beginning. First one I had that came with the station, worked fine with two stations as well. (one transmitter, two clock/weather receivers). Then one day.. it fell and broke. oh well.. get a new one. worked just fine. then it fell and broke.. most of this is my fault since I never attached them to the wall or anything. just laying on an old bench car seat on the back porch. received another. i think the batteries in this one just died,, tried new batteries.. didn't work.... ok.. got this one.. (ok,, this is the 4th one if you're keeping track. it didn't work. tried every which way to put the batteries in. transmitter first.. receiver first.. etc.. then it dawned on me.... there were still batteries in one of the other previous transmitters. took them out.. and now the new one worked like a charm. evidently it was still trying to transmit (something), and was interfering with the new one. Just thought i'd pass my experience on for those who say this item doesn't work.
Review: Replacement Sensor - I purchased this wireless sensor because my La Crosse Digital Clock's (model WS-8157U-CH-IT) sensor died about a year after I purchased it. After looking at all my options, which include a new clock, It seemed this was the most economical way to go because I liked the weather forecasting of the atomic clock, the outdoor temperature, and the color of my original clock. The new sensor started transmitting right away and the clock synced up with it in only a few moments. I have had no issues at all with the new sensor. I have purchased a total of 3 La Cross atomic clocks with remote sensors over the last 4 years and it seems that the sensor will die after about one year in half of them. So, I have a concern how this sensor will work over the course of the year, but I think its worth it for me at this point.

## Questions & Answers

**Q: Is the La Crosse Technology TX37U-IT compatible with the TX31U-IT?**
A: I think it is NOT COMPATIBLE.A quick search on the LaCrosse website shows that the TX31U-IT is a "Temperature & Humidity for 1500 series & 1900 series stations." . Whereas the TX37U-IT is only a temperature sensor. The TX37U-IT is NOT compatible with ANY of the 1500 and 1900 series stations. It is true that they both use the 915MHz frequency.  Hope this helps!

**Q: will one tx37u-it work with two compatible clocks at the same time?**
A: Yes as long as the clock runs on the 915MHz.  If the original outdoor transmitter was a TX37U-IT Wireless Outdoor Temperature Sensor then it will work with multiple clocks of the same frequency. The clock receives the radio signal from sensor through the air just like your car radio works.  So many clocks that are within range will work at the same time.

**Q: Do Z-Wave devices, such as motorized shades, cause interference for this transmitter?**
A: I really don't know. Possibly if the motorized shape operate remotely?

**Q: My transmitter (older) has written on the back tx-37u. Is that the same as the tx_37u-it?**
A: You need to contact the company.
