Hello Brian,
This is something I always thought it was an error of the ws2010. But I want to present it to you for your opinion.
Here is the output of the Get Interface Time button:
DCF sync
Time :148:03:00
Date:00/00/2010
Also I always get a Battery LOW indication but I changed the batteries for new ones and it still gives me this error:
With HF
Sensors: 0-9
DCF assync
Battery LOW
Interface version 2.4
Interval time 3 minutes
Maybe it is something in the interface?
