Setting up the unit seemed easy enough and it connected as long as it was in the same room. The minute I took the sensor outside it could not connect and it is only about 50 feet away. Now the temperature is blinking and I can't find what does that. Also, the display is always dim it only gets bright when I touch it and I can't find a reason for that either. I have tried support to no avail basically there is no support. I had an Acurite for years and now I am sorry that I did not stick with it but the write-ups on this one seemed better. Not happy at all.
OK so I am editing the original post as the support people finally got back to me. They fixed the connection issue and the issue of the rain amount being wrong. The rain was a user error (read the instructions) and the connection solution worked even though it seemed odd... You have to remove all power from both devices (batteries and plug) and let the system sit for 12 hours after I did that the connection worked very well I still don't have a solution to why the unit dims all the time but I can live with that as long as the data is accurate.
Final edit ... the support that I received was very good they were able to work out all of the issues I had. It is now working like a champ. I am very happy with the device and would definitely recommend it.
