La Crosse Alerts 926-25101-GP Features

La Crosse Alerts 926-25101-GP Mobile appThe 926-25101-GP by La Crosse Alerts is designed specifically for those who would like to measure temperature and humidity in places they don’t access frequently. The device sends alerts directly to your phone through text notifying you of the temperature or humidity readings and measures to be taken. You can also access these readings directly through the La Crosse App for iPhone or Android.

This unit comes with a 6ft detachable DRY indoor probe for inserting in places you want to get readings. Unlike the WET probe, the DRY probe cannot be submerged in liquids. You will have to purchase a WET probe if you wish to measure temperatures in liquids.

The La Crosse Alerts 926-25101-GP sensors measure three major things:

  • Ambient Air Temperature
  • Ambient Humidity
  • Probe Temperature

To use this sensor effectively, you need a high speed internet connection and a network router that will be connected to the Gateway. The sensors also need 2 AAA Alkaline batteries each. This device operates within a temperature range of -40 to 140 degrees Fahrenheit while its humidity range is 3-99%.

This unit comes with 1 sensor but it can support up to 5 of them. Additional sensors can be bought separately. Click here to view them.

When installed in place and configured, the device will be sending you alerts whenever temperatures rise above or fall below your preferred levels. The alerts will be delivered through its smartphone app, text, or email. The same happens when humidity rises or falls.

La Crosse Alerts saves you time and money by warning you in advance so that you can take necessary measures early enough. It also sends alerts when the internet or sensor connection is lost and when batteries are weak.

Among the applications of the La Crosse 926-25101-GP include monitoring temperature and humidity levels near sinks, water pumps, plants, utility rooms, dishwashers, washing machines, pet shelters, greenhouses, and plumbing. It is also perfect in homes where kids tend to leave the refrigerator door open.

Installation & Set Up

Installing La Crosse Alerts 926-25101-GP is easy. However, if you don’t follow the guide correctly then you might end up getting wrong readings which are in no way as a result of faulty equipment. To install this unit, follow the steps highlighted below:

  1. First, connect your gateway to your router using the Ethernet cable. Ensure that your router and gateway are connected to a power input and the router is working.
  2. Next, add batteries to the wireless sensors and connect the dry probe if needed. The sensor is responsible for sending data to the gateway so make sure it is working first. You should also set up the sensor not more than 200 feet away from the gateway.
  3. Download the La Crosse Alerts mobile app or log in to, sign up for an account, and follow the prompts to register your gateway and sensors. Once set up you should be able to receive temperature and humidity readings directly to your phone or computer.
Don’t place the sensors near the ceiling, ground, or fireplace since this may trigger false alerts. Sensors shouldn’t face directly towards the sun either.

When installing the probe, make sure to use the right one. There are different types of probes and each of them serves a different purpose as shown here:

  • TX60: The dry probe has a black tip while the wet probe has a silver tip. The wet probe is designed to be used for immersion in places like swimming pools and tubs.
  • TX70/71: In this range, the flat plate is used to compare wet to dry conditions.
Remember that these probes cannot be interchanged since the TX60 range isn’t designed to do what the TX70/71 range can do and vice versa.

The performance of 926-25101-GP temperature and humidity sensor from La Crosse depends of two major things; the positioning of the probe/sensor and your internet connection. Make sure the probe is properly positioned as explained in the installation guide for you to get accurate results.

If properly installed, this gadget sends data, albeit a few minutes late, to your smartphone whenever there are any unusual temperature changes. If you don’t have an iPhone or Android smartphone, then visit and log in to receive temperature and humidity data.

The sensor body monitors both temperature and humidity while the probe monitors a second temperature reading. You can easily use one sensor and a probe to measure the refrigerator temperature and the freezer reading.

The most important thing of all is that these sensors are accurate. They operate within a temperature range of -40°F to 140°F while the humidity range is 3-99%. However, the alerts may come in a few minutes late sometimes when the actual readings may have changed a little. The wireless sensor only transmits up to 200 feet in open air and the range will be shorter in case of obstructions.

Although the iPhone and Android apps work, they need some updating. The interface, just like on the La Crosse website, looks dated and not very user friendly.

Final Words

Overall, La Crosse Alerts 926-25101-GP is a useful device for monitoring temperature and humidity. Whether in the freezer, greenhouse, garden, patio, swimming pool, or hot tub, this device does a great job monitoring and sending alerts via text, email, and smartphone app. If you are looking for the most convenient and affordable way to monitor temperature and humidity around the home, then this is the right temperature sensor for you.
