Ikea motion sensor

You shouldn’t have that long a delay
I use one in my hall that triggers a morning routine and three lights come on nearly instantly.

Maybe I have many “jumps” between several zigbee units. I´ll continue trying different ways and see if I can improve it somehow.

Is there a chance the motion sensor has the same incompatibility as the Tradfri 5 button remote with V1 hubs?

Yes. It is incompatible with the v1 Hub too. Sorry for the bad news.

Hello, 3 minutes is too many time for me, there are some way to change it for example to 30 seconds to clear the presence+


It is a device hard coded value to keep batteries last long. If you need something more instant buy a SmartSence/Smartthings motion sensor.

@JDRoberts, I remember that I have read somewhere that there is some functional sensor difference between the old and new IKEA motion sensors (PIR vs ???)

Do you remember what is it? What sensor the old one has? Or do I remember wrongly?

As far as I know, they are both PR sensors.

Sorry to necro this thread a bit, but I needed some consultation on using this sensor.

I just started using one of the newer sensors to activate a light on my porch at night.
The back of the sensor is set to the ‘night’ mode (the moon) and the brightness to the full, but regardless of those the sensor keeps detecting motion during the day.

Is that functionality totally lost when you use the sensor in SmartThings?

My automation only runs at night, so all the sensor is doing is sending about 10-12 unnecessary motion detected/undetected messages a day. Would that harm the battery life much?

@pavichokche - Yes, that functionality is lost. Set your Automation rule to turn on the light between sunset and sunrise.

The device would detect motion anyhow and would wake up I believe, it would just not turn on the light bulb if connected to that directly. (Long press pairing.)

Yeah I already have the automation configured that way, I was just worried about the battery life.

I had tried to do a direct pairing between the sensor and the bulb, the way I have with my remotes and bulbs elsewhere, but it just wouldn’t pair no matter how long I held the button near the bulb. Kind of unfortunate.

The battery life of the motion sensor is quite good, but it still goes dead without showing low percentage values.

I paired the new model of the sensor to my V2 hub, but it fails to detect motion, any tips to what I can try?

Try to re-pair it again.

Thanks, it works now with the re-pair., but I had to use the classic app to pair again. The new app somehow didn’t get it. Battery has dropped to 33% though, is this at all reliable info?

Time will tell, but you will see that the battery will go up and down again and again.

Here is a summary and my success in pairing the new IKEA Motion sensor E1745 with SmartThings v3 in Australia.

The Australian ST compatibility only lists the older version however I was able to pair it with my ST. Her is what I did. I opened the new ST app on my phone, clicked to add new device by brand, selects IKEA the motion sensor.

Once the process of scanning is initiated, press the pairing button 4 times and not the 10sec as instructed.

My motion sensor detects motion quickly about 1sec however it takes about 2-3min to reset, meaning it will show motion detected for a minimum period of 2-3min.


The instructions are there still for the old version.

That is the expected behavior for the motion sensor, it has a 3 minutes grace period, when it is blind. It is due to battery preservation purposes.

It’s still a nice cheap motion sensor that works directly with the ST Hub, if you don’t need a fast detecting sensor.

Unfortunately the DH is cloud execution one. But I fully agree with you. I have few…
