If it is not too much trouble, an error message derived from the three digit code to the RX display would be very useful, I am often losing data from TX units due to them failing for one reason or the other, very frustrating, an LED output would give me the prompt to resolve quickly.

I am often losing data from TX units due to them failing for one reason or the other, very frustrating, ...

Could you please tell me what kind of TX and RX unit are you using? According to my registers, you don't have any WeatherDuino hardware. I'm wrong?

In any case, the most probable cause for losing data is poor RF reception.

Both the Pro2 and the Pro2 PLUS already have a led which blinks every time the RX unit receives a data packets from any of the TX units.

There is also a way to check, if we haven't receive data in the last 5 minutes, from any of the three main sensors of the system, wind, rain, and temp/hum.
With the Pro2 you will need the Wireless display unit for that, on the Pro2 PLUS, the data field for the corresponding sensors, appears with three dashes.
