Strange thing happened to my Sky here in The Netherlands.
I installed the Sky in october 2018 and te battery voltage has been around 3.4V since then.
Suddenly during my holiday, the Sky went offline on the 24th of August.
When I got home after 1 week, I powercycled the HUB, but the Sky did not come back.
So I went up the roof and powercycled the Sky. Fortunately the Sky was online again within 1 minute.
However: the voltage has dropped from 3.4v to 3.1v in 1 week without being online (see picture).
Is there something wrong with my Sky?
Or was there a firmware upgrade the shutdown my Sky?
