Hi,
Move the “L Out” to the same connector as the “L In”. This would effectively bridge the live and have permanent power to the bulb. The Sonoff relay would still “click” when you pushed the light switch but not do anything. You would then need an automation to trigger the bulb on when the relay turns on.
Something similar to this automation that I have (used an Xiaomi Button to trigger the light)
- id: brandonlight003
alias: Brandon's Light
trigger:
- platform: state
entity_id: sensor.brandon_xiaomi_switch
to: single
action:
- service: light.toggle
entity_id: light.hue_spare_brandon
You may have to have an “on” automation and an “off” automation. Mine is just a push button so it just toggles on/off.
