| * 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. | |

@zierbeek Sorry for the delayed reply. I added a Shelly so I could get 24/7 motion events from an outdoor mains powered sensor. Is this way, I can use it as an extension to both my alarm system and surveillance system. So when the alarm is set, if this outdoor PIR triggers, it means someone is hovering around outside my house so I get HA to notify me.
If you have a device that supports Shelly Scripts (I'm using a Shelly 1 Plus), you can use this setup, but run the automation locally (basic script below). This has the benefit that it will work as expected even if the wifi drops. You can obviously still control the switch and get the PIR state in Home Assistant. I bought a Sebson IR_OUT_E on Amazon, and mine didn't work initially, although sticking a 330kΩ resistor between the switched live and SW port on the shelly sorted it.
Shelly script:
Shelly.addEventHandler(
function (event, ud) {
if((event.info.state || false) && event.component === 'input:0'){
// PIR Triggered
Shelly.call('Switch.Set', {id: '0', on: true});
}
},
null
);
I then use an auto-off timer on the Shelly, which means I can configure it without having to turn the dial on the PIR sensor.
@BenHarris Thank you so much for your input. That's very helpful.
Hi,
I have been trying to get the above working with Shelly1 and Home Assistant. As per fist post
I can see in HA, PIR Motion Sensor, Sensors shows as input = Off, PIR trigger's it then shows On.
Light does not come ON.
On Shelly screen the switch is all off,when PIR is triggered, little bar lights up, still no light.
If I click the button,light comes on, and stays on.
Any help appreciatted. Deblen
@Deblen Did you detach the switch input from the relay using the Shelly's webpage? Have you got the Shelly in HA using MQTT or with the Shelly integration? Can you control the relay (light) in HA?
Hi Thanks for the quick reply.
Detached via Shelly,
Using Shelly in HA using MQTT
No cannot control the light,
I can hear the PIR click.
The only way light turns on is clicking the button on the actual shelly, circle turns blue.
If I trigger pir, the little line in the circle will turn on,
Deblen
@Deblen Seems there is something wrong with your MQTT YAML if you can't control the relay from HA? Without that, nothing is going to work. I'd be tempted to migrate everything to the Shelly integration as that works really well and is just a whole lot easier as no YAML is required to get the device into HA.
Thanks, will try Shelly Intergration.
Deblen
Hi, I could not find how to do it via Shelly.
I then decided to try the post from 4romany, above.
I was able to get it to work.

Posting my question here since you seem to know your stuff. I have a similar setup, output of motion sensor to switch input on Shelly, but my Shelly keeps on detecting 'on' probably because there is still a small voltage on the motion sensor's output, but high enough for Shelly to detect it as 'on'... Any tips?

The 330kΩ resistors resolved the issue in my case (see my reply above). For reference, these are the once I bought: https://www.ebay.co.uk/itm/252024737412. I soldered one inline and stuck some heat shrink over it. Been working perfectly for 18 months now.
@BenHarris Thanks for chiming in. That is what I was going to suggest. Appreciate the input. Actually might need to do that to mine as it's been a bit erratic lately too!

@BenHarris Just wanted to confirm this before i go ahead and do something similar - i have a couple of mains powered PIR units and there is a continual voltage output from them to the Shelly (i have flashed with Tasmota) - are you saying you just put the Resistor in between the (supposedly !) switched live output of the PIR and where it goes into the SW1 input on the Shelly ? i.e. wired it inline with the cable and then put the input to the SW1 input of the shelly ?
Regards
Craig

I tried this (the inline method) with various resistor values but no luck: Shelly never detects the signal, so was thinking the resistance was too high, but lowering it did also not help. Really looking forward to a solution where one could measure something and calculate what resistor values would make sense.
@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.
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.
Hi! just a small question. Why did you make your motion sensor smart? To track activity?
