LASCAR EL-WiFi-T Wireless Temperature Data Logger

I believe the cloud service was originally free. Now it cost $$$. Temp Stick does the same thing, is free, and can also be viewed on PC, phone, or cloud, and there is no cost. Better device at a lower price and batteries last for months.

Works well bought it for our 5th wheel trailer to warn us if the air conditioner malfunctions when we are out for the day and dogs are in trailer.

Bought 3, first one was DOA, other two cant hold a charge 3 months out. Constant disconnecting to router. Frankly I am disappointed on how much of a PITA these have caused me. Will not buy again,especially for $99.

Using in a customers server room. So far so go - we are thinking of using the same one in our server room.

I had great luck with the first one I bought, so much so that I bought a couple more. I bought 2 of the EL-Wifi-TH and 1 of the EL-WiFi-T. They are essentially the same thing only the T does not measure humidity. Problems started a few months after I got them. The battery lasted less than a week, so I was constantly running out of power. The devices would stop taking readings and the latest one I bought has now stopped responding completely. It won't even connect direct with a USB connection so it's essentially useless. I really like the concept of being able to track the temperature and not have to connect something to the PC, but I've wasted a lot of time trying to get these to work. Until they sort out the problems, I would get a tracker that requires connection to the PC and does not have WiFi.
