With LIFX Z (v1.21), the multizone state messages report zero brightness when the power is off. This differes from the basic state message where the set brightness is reported even while power is off.
This seems like a bug and it makes it impossible to do a temporary effect from the powered off state and then return all zones to their previous state.
I verified that e.g. the iOS effect “Candle Flicker” indeed has this problem: the brightness ends up at 1% if the effect is started from a powered off state and then stopped again.
Is there any chance of getting this fixed?
