    TEMPSPOTFL - WiFi Water Temperature Sensor

    WiFi Temperature Sensor for Liquids

    The TEMPSPOTFL is a WiFi Temperature Sensor for monitoring the temperature of water or any other non-combustible fluids. The TEMPSPOTFL is capable of monitoring temperatures between -40F and 212F making it perfect for monitoring everything from personal hot tubs to industrial applications.

    When the sensor is triggered by the user's set temperature level, an alert will be sent by email or text message.  Users can also login and view the history of the temperature sensor(s), and make changes to alerts as needed. 

    The SpotProtect cloud service is FREE for a single contact.  A Premiere subscription is also available to allow multiple contacts and faster heartbeat monitoring. 

    Perfect for applications where a phone line is either unavailable or impractical!

    Note:  A SpotCable, sold separately is required to initially program the WiFi sensor(s).

    NOTE:  As with any monitoring device you must ensure it is installed correctly and tested regularly to ensure it is in working order and reporting as expected.  The WIFI device must be located in a dry room temperature location.  Do not install it outdoors or in a humid environment.

    excellent remote wifi temperature monitor

    I researched for a device to remotely---via smartphone and/or internet--monitor my hot tub temperature to alert me if the temperature drops below--say 95 degrees Fahrenheit--so I can correct the problem before expensive damage occurs. So far the monitor works great--it is reliable and accurate. Setup was fairly easy but could use some improved automated features. An android app would be nice--I hear it is in the works! Also be aware the sensor module is NOT waterproof but I simply placed mine inside a Pelican protector case --model 1010 -- I got from amazon. I drilled 2 holes in the Pelican case to allow for the antenna and the 3 foot temp probe then added a little silicon caulk around the holes I drilled. I would highly recommend this product. so far

    Works great, but difficult to set up - NO MACINTOSH CLIENT TO CONFIGURE

    i had a freeze alarm which i've used for years, so i thought i'd try their wifi hot tub alarm. arrived quickly, but NO WRITTEN DIRECTIONS, only on the outside of the box. Nowhere on their website do they mention that you need a PC (who uses those anymore?) to configure - if you have a Mac you're out of luck. But since finding someone with a PC to configure, it seems to work very well.

    Easy to hook up, works great

    I ordered this temp sensor, followed the online instructions, and started monitoring my hot tub temperature with it. In Minnesota, the temps get down to 30 below zero, so it is important to be alerted as soon as there is a problem with a hot tub. I can go on my account and set the phone numbers I want called, the email I want alerted, and what temperature I would like an alert sent. I have it set to trigger an alert at 95 degrees. I took it out of the water to test it and received a text message in less than a minute. I can also set how often I want the current temp sent to my account, so if I log in to my account I can see the temp changes over a day, week, month on a bar graph. Pretty cool feature, I could see that my temp would vary between 102.4 degrees and 103.7 degrees. It is set for 102. Very happy with the product, money well spent....I am in the hot tub industry and it's the first product I've gotten that I'm happy with and would sell to my own customers.
