Hi, reviving this old thread. i want to substitute an impulse relay (HAGER EP 515N) by a shelly 1.
The impulse relay is now controlled by button A which is connected to power group 1.
The garden lights that are controlled by the impulse relay are connected to power group 2 (so live/neutral wire come from different group).
How would the wiring work with shelly 1?
The live wire from group 2 would go to L and I of the shelly
The neutral wire group 2 would go to N of the shelly
The garden lights would be connected to O of the shelly
The neutral wire of the garden lights goes to group 2 neutral
The SW input would be the live wire from button A ; but where would the neutral from button A (group 1) go ? That neutral is now connected to A2 of the impulse relay.
Hope this is clearly explained as I don't really know how to draw this easiliy.
thanks !!
