Making an outdoor motion sensor smart using a Shelly 1

shelly_pir.yaml

/** 
* I figured out you can fit a Shelly 1 inside the case of many outdoor motion sensors. 
* Coupled with that fact that recently, Shelly added a feature to de-couple the switch from the relay 
* so they act independently, makes this a great combo! Simply wire the output of the PIR motion sensor 
* (the wire that normally goes to your outdoor light) to the switch input of the Shelly and wire 
* the lightbulb to the L output of the Shelly. Then, in the Shelly app or directly via the devices webpage, 
* select the button type as 'Detached Switch' and use the code below to make it work normally. 
* Don't forget to adjust the daylight sensitivity to full daylight if you want the motion detection to work 24/7.

For reference, I just popped a Shelly 1 PM on the bench with just a 230V AC supply and unloaded, the SW input measures 126V AC.

Yeah I am really trying to understand what they are doing – my electrician when I get him to wire them up saw the same thing and could not understand it either Craig From: xbmcnut ***@***.***> Sent: Friday, July 7, 2023 8:58 AM To: xbmcnut ***@***.***> Cc: Comment ***@***.***> Subject: Re: xbmcnut/shelly_pir.yaml @xbmcnut commented on this gist.
