Hi
First time installing a smart relay so apologies if im missing something basic. I have a shelly 1 wired up as per the attachment. The switch cable runs to a 3 gang switch and is also part of a 2 way circuit.
When connected it appears to work fine but after a number of switches (I think mainly from the wall) the shelly appears to drop from the network like its been turned off (neither smart of physical switch works) and then comes back after a few seconds. Then every now and then it wont come back on at all and I need to reset it by toggeling the fuse box.
Any suggestions would be greatly appreciated.
