La Crosse Technology LTV-Pool-INT Wireless Digital Pool Thermometer

Battery powered pool thermometer connects to your WiFi and allows you to view pool temp from your phone via the La Crosse View App or from the digital display on top of the thermometer. Works as advertised, was easy to set up, and love the convenience. I was also able to set up notifications for when my pool temp increases to my minimum swimming temperature of 80F so I know pool season has begun, and when the temp decreases below 80F so I know not to take the polar plunge.

very accurate, very easy to read, does seem to have a short battery life I will know more in about a month.

Very good working thermometer. We have had it in our above ground pool for 2 seasons now. The only thing that you must realize is that it reads the temperature at the very top surface of the water. So if the pump isn’t running or people aren’t swimming in it to move water around, it’s definitely not the temperature you think it is when jumping in ! Top surface of the water is usually much warmer.The batteries last the whole season, which is about 4 4 1/2 months here.The display on top of the unit is descent however hard to read on a sunny day. I mostly use the app to see what the temperature is, which really is convenient.We tie it off to a porch post to keep it from becoming a pool toy, ha!Highly recommend, especially for the fair price!

I have purchased 2 of the units and have had good experience with Lacrosse view products but this is a bad product. I purchased the first one on Amazon for my Florida pool. At first I was impressed with the unit and its connection to the Lacrosse app. Display was excellent and right on accuracy. After several months moisture started to appear under the glass display and finally the display itself failed apparently from moisture leaking in. Since it was under warranty I contacted Lacrosse and was treated extremely well when I explained the problem. I was told they were out of production and a new model would be forth coming and would be sent to me when back in production. Several months passed and I had pretty much assumed I was out of luck who I was surprised by the delivery of a new unit which appeared the exact same as the first. Two weeks ago, the same thing happened again starting with the under glass moisture and finally today a complete failure. New batteries had no effect. DIW- Dead in the water.

My wife thought this was an unnecessary toy at first, but quickly realized that being able to view the pool temp from inside is actually pretty cool. Being able to see the pool temp on our La Crosse weather station in the morning helps us decide whether to fire up the heater without actually going outside to check the temp.As others have mentioned, the display gets cloudy with condensation making it hard to read. The moisture does not seem to affect the performance of the sensor.

This thermometer doesn't last. Mine worked great until recently, about 6 month mark and the display went wonky. Checked batteries and they are good. The display did get moisture in it too just like others said. I don't think this product is woth $40 because it doesn't last. Will just get a cheap standard thermometer to replace it since Amazon could not exchange it, only refund.

I'm using this in a swim spa with a very thick and heavy cover. The device seems to work fine through that cover.However, the readings do some strange and unrealistic spikes. This tub is set for 80 degrees. It takes hours for a tub this size to change much, but the graph shows these momentary spikes to nearly 100 degrees. It's not the jets causing it as in most swimspa's, including this one, the jets are all at one end and they'd push this device to the other end immediately. Just a glitch I guess.

I like that I can get a pool temp readout in my house but these seem to last about 18 months before the seals fail. If you buy the replacement insurance you can just submit a claim.
