    This is great, thank you for taking the time to share your knowledge. I like that little jumper bridge.. that is great. I wish I would have seen this video before.. I fried a sonoffsv while doing the magnetic door lock.

    Hi there.
    I have followed your videos and they are great. I have setup my PIR and Sonoff similar to your video. The PIR is connected to GPIO3 and I would like it to turn a hue light on with automation
    For some reason I see the sensor state changing in sonoff console from Yes to No (on or off), however I do not know why the Binary sensor is not changing state in the states tool
    When I look at the state it shows off. I does not change to on even when the sonoff consoles show it change from off to on and on to off.
    I hope that makes sense, and hope you can help.
    I am still learning and i think it might have something to do with the rules or MQTT setup
    Please help as once this is working I will setup 3 more around the house.
    NOTE:
    I am not switching the local relay on the Sonoff, I just want to switch on a light in the bedroom using MQTT and automation.
    Cheers
