Product review (1 stars): Just about dead on arrival
I ordered the AcuRite 3 sensor temperature and humidity instrument because it was exactly what I wanted and it promised email capability from the sensors. The control unit and sensors came within Amazon's reliable two days Prime shipping.  I turned on the unit and registered with AcuRite's server. There are two blue lights that they call sensor lights.  The instructions are unclear about where these lights are located.  I couldn't find them until until I saw that after a delay they began illuminating on the sides of the unit. They were blinking and that was supposed to be the way they worked until they turned solid and then you were connected through the internet.  I watched them until I saw they were both on and fully solid.  Turned my head and suddenly there were no lights lit.  I tried removing the power and reattaching it, to no avail. Pulled out the internet cable and reattached it, to no avail. The unit was completely dead; it never did connect as it was supposed to.  No problem, I would call technical support. So, basically, I thought that I could work with their support to probably send the control unit back for a replacement (and take the chance that that a replacement unit may not result in one that worked) or I could send the whole thing back to Amazon. Called the first wats number on the instruction sheet packaged with the control unit and the recording said the number was disconnected. Okay so I found a different phone number on the instruction sheet from the sensor and called it. A recording came on and said that their phone support was not working because of a server problem. (really?) So, I could not get past the recorded message. Called again later in the day and received the same response. The third call was the same and it became my last, because I gave it up in frustration.  I decided that technical support would not be of help because it didn't seem to exist and the unit was too far gone to fool with, so I sent it back to Amazon for a refund. I had the unit for just less than1/2 day.

My experience was not good, yours may be better, but I doubt it. Take heed in the negative reviews other have given this product. It's offering a lot of technology in a package that is cheaply made without any quality control.  I doubt if anyone ever tested this unit when it came off the assembly line.  If you can get it to work without technical support your are lucky, but don't trust your luck on this one.

To my way of thinking, there is no excuse for saying your support system is not working.
