Yesterday, I did more work on mine to try and understand what was going on.
Firstly after advice from support team, and enabling battery card, I found that neither AIR nor SKY existed under my station option, and I could not turn on the battery card option. So pulled everything in, cleaned it up, and added batteries to my sky unit to effectively replace the SPA. Amazing how even though the SKY & AIR were not listed with my station it has carried on reporting.
Anyway, deleted my old station (loss of historical data doesn’t both me) and built a new entry. SKY & AIR both there and able to switch on battery card. Put everything back outside, and will watch now to see what happens. Batteries look good. Just need to remember that the station ID number has changed now so must update a few links here and there. But let’s see what happens going forward.
Just thought I’d let others know (for now possibly don’t know yet) how I resolved my problem.
Thanks support for your advice, to help me along the way as I’m no expert here, in fact the unit is in place and reporting, kinda like left to its own devices really!
