For several months I have one piston that every morning at 07.50 wake my wife by using one amazon echo (ring, meteo, calendar …)
Well, yesterday the piston left at 07.06 !
And then, usually at 07.50 … I love this system

That time stamp appears when it runs automatically, or when the Test button is pressed.
(and probably also if another device calls that piston)

It would have been interesting to be able to see the log to see what happened. I am wondering if the 6:50 timer didn’t happen and a recovery event fired that got treated as the delayed timer.
