    Hi,

    Struggling to see what I am doing wrong and think I must be missing something blindingly obvious....Have looked through posts on this forum and videos, etc and think I have the right setup but can't have. Would really appreciate advice please.

    Before installing Shelly, non-timed extractor fan in bathroom comes on with light switch. When I install the Shelly, the light no longer starts the fan and it can only be started by the Shelly. Before and after wiring diagrams attached.

    I have 3 Shelly 1s. Have checked they work on a friends test rig and have borrowed one of his Shelly's that works correctly. Have same result when I substitute each.

    - O is connected to the fan live terminal

    - I to permanent live via isolation switch

    - SW is connected to switched live output from the light switch

    - L to permanent live via isolation switch

    - N to neutral via isolation switch
