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.

@michamichamicha There is a bit of chatter at the beginning of this thread about adding another relay between the motion sensor and the Shelly input. It seems the Shelly SW input is 'floating' as indicated by this post here. Mine was working flawlessly in the early days but in the last 12 months, it triggers randomly all the time so I'm going to remove it and debug and I'll report the findings here.

Yep.i just connected a SSR between the motion sensor and the Shelly sw1 input and works a treat Get Outlook for Android<https://aka.ms/AAb9ysg>

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.
