Here are two snap of my system. The Access shows full signal but the dashboard shows it in the yellow and poor signal. WHY is this going on? And I get alerts from Acurite and weather underground.... But then again after about 20 minutes it's back to normal.
The Access is very sensitive to other signals from Microwaves, routers, modems, cell phones, LED lights and I wouldn't even doubt from TVs also. Mine do the same thing. This new Access has been a pain for many if you read through the forums. I guess the work great under ideal conditions if you live out in the country without much interference.
They work OK in a dense Silicon Valley urban setting. I see a dozen WiFi (all secure), My Neighbors 5 in 1, someones 'Tower' sensor. The neighbor with the 5 in 1 is also Ham Radio operator (way more power than any Cell phone). There is even a Micro-cell pole within 500'I suspect part of the problem is poor quality components mixed in with the good ones. Just read here about how many folk get wrong power adapters in the box, power adapters that up and die at the slightest power burp. Cheapest stuff is used.
