Hello again,
I've got an issue, not necessary related to shelly device directly. The whole installation has worked perfectly till temperature dropped. We've got now less than -5C and the fence opener stopped to work - I can hear the click of the shelly's relay and tiny click at the opener itself, but it does not release the fence. I checked the voltage on the shelly's terminals showing 12V but only 8V on the locker's terminals. I believe it is the reason. How can I overcome it? The most obvious solution would be to install DC adaptor with higher voltage, say 15V, but wouldn't I burn Shelly device when I connect it such way?
Thanks
Krzysztof
