Hi,
I have 2 Shelly Plus 2PM devices controlling covers. They are calibrated and work ok until a power is lost after which they lose the cover position and have to be fully opened or fully closed before they again are aware of the cover position. Firmware 0.10.3 Both have eco mode disabled as with eco mode they would sometimes lose position even without power outage.
I have also a Shelly 2.5 which also controls another cover and it never loses cover position neither on power loss.
Thanks!
