(a)  the two colored dots to the left of the time display

Hi Jim,

This is a good question, because until now I did not have the opportunity to talk about this on the forum. Considering the relevance of the question, I create a new thread about this matter. Please refer to it here:

(b)  the com led

On the Pro2 PLUS, the COM_LED have exactly the same function than in all previous Pro2 receiver units, already described in several topics on the forum, however I will describe its function again.

At startup the COM_LED remains ON, until the system receives data from the outside sensors (Temperature / Humidity, Wind, and Rain), also giving you a visual signal to not attempt to start the weather software yet (Cumulus or any other).
After system initialization, the COM_LED goes off, and you could start your favourite weather software, then the COM_LED will blink every time the your weather software requests a data packet (more or less at each second) to the WeatherDuino receiver.
