Battery card for sky does not show. I can see the battery card for air. If I go into the diagnostic (advanced) page for sky I do see battery voltage.
@davidlusskin - I had to turn the battery card off then on. When the battery card was turned back on the cards for both devices showed up. I think this is an artifact of having the Air only for a while and then adding the Sky later. My guess is the inverse would happen to if one had the Sky running and set up before adding an Air.
That fixed it thanks.
You are quite correct!
perfect - answers the query I was going to check this morning
