Useful and simple device
Useful and simple device. Delivery has been fast. With an almost plug'n'play installation and quick configuration, the device has a complete monitoring report and a nice iPhone/Android App! Highly recommended brand!
It wasn't easy, but we did it!

It wasn't easy, but we did it!
This is my second WiFi system. The first was purchased in 2008 and worked like a charm. In fact, twice it notified us of a problem with our second home. So, when I needed an updated system, I did not hesitate to repurchase another Tempature@lert WiFi system. 

I am a novice.  I barely understand ports, access points, or wireless network configurations. However, when I purchased my WiFi model for our second home [as required by our insurance company], and it did not send emails as I needed for insurance compliance, Temperature@lert Help team was FANTASTIC! They gave me suggestions, provided screen shots, and followed up to be sure I was able to accomplish what was needed.  

I a very satisfied and happy with my WiFi system and recommend it for anyone with a second home! 
Great Product. App Needs Work

Great Product. App Needs Work
I own a meat shop and the device works amazing! I subscribed to sensor cloud and the website's sensor cloud is much more useful than the iOS app. You can not change settings or view all of the temperatures at once in this app. It needs more features. And an HD version for the iPad. Also the For tech support, They never answered their phone and they took days to respond to e-mails. They really need to work on their tech support. I did like the device so much that I bought a second one for the rest of my freezers.

Our AC in the computer room shut off unexpectedly, and the temperature in the room quickly rose.  I went on line, and ordered this device.  It does exactly what I want: Constant Monitoring, High Temp Alerts, and a daily summary.

The system works great, really does a nice job, simple, easy to set up
We are using the system to monitor the refrigerators at our restaurant. The system works great, really does a nice job, simple, easy to set up. The only suggestion I have is regarding the output file that is emailed each day. It is not in a format that can be easily opened in excel. A simple csv output option would be nice. Perhaps this could be incorporated into a future firmware upgrade.
