My two whisperers stopped due to lack of sun. The new one started communicating again.

The old one started communicating but then stopped while the battery was still above 90%.

Seems a communication problem 

Blue light blinking turned quickly to white light blinking.

After blinking a few minutes it stopped but is not connected to the App.

Tried putting it ON close to controller and then close to WiFi router, the result is the same, no connection.

Is the whisperer dead ? Should I buy a new one ?

Thanks
