IKEA Vallhorn Motion Sensor

Devices & Integrations
1

The new Ikea Vallhorn motion sensor is available in parts of Europe now. I am fed up having to replace batteries in my old ST motion sensors so was thinking of buying a few of these. Has anyone got them working successfully with ST? Is there an Edge driver out for them? I have searched and cant see anything.

Not available in all stores yet, but I might get one why they are out

It does pair to smartthings, but comes in incorrectly as an Illumination sensor. I tried changing the driver to a generic motion sensor, but so far it’s not functioning.

For anyone else who hasn’t heard of these, here’s a link. Should be interesting to see how well these work considering the price point.

Much better looking than their last generation…

This device seems to use the occupancy cluster to detect movement, different from the TRADFRI sensor.
I don’t know if it needs a time out to reset the motion event or if the rear physical selector of the sensor that regulates the lighting time of the lights between 1 and 5 minutes will also reset the motion.

I don’t know if it uses the voltage or battery percentage attribute. I have set percentage, if it doesn’t work I change it.

It works.

Both the motion sensor and illumination sensors are reporting now.

The default motion timeout (no motion) appears to be under or around 30 seconds. There doesn’t appear to be be any cool off after the reset either.

Are Battery info correct?

Yes, sorry. The battery information is also reporting correctly as a percentage.

Shows 100% or 50%.?

You have to wait a few hours without movement to see if it shows offline or not

It shows 91%.

I’m using some of IKEAs rechargeable AAAs. That % is similar to when I use rechargeable AAAs in other devices. I can swap them with other AAAs and see if the percentage changes.

I’ll move it to a dark location and see if it goes offline

This is good.

There are IKEA devices that do not follow the Zigbee standard for battery percentage and does not have to divide the value sent by the device by 2.
It seems that this one does meet the standard

Interestingly, in the “Signal Metrics” section, it shows a timestamp update exactly 1 hour from its last “event”, and then updates the time stamp once an hour every hour after that

That’s ok.

Signal metrics are updated when a message arrives from the illuminance device every 3600 sec maximum, or battery, every 6 hours maximum.

That means that it has been configured correctly and periodic messages are received and that means that it does not appear offline.

In this device I could add that they are also updated with movement messages, which are handled manually.

Hi @trillexer

I have merged the TEST driver with the Mc driver.

You only have to make a driver change to this version of the Mc driver. Since the device is already configured, everything will continue to work correctly.

Then, you should delete the TEST driver from your Hub

I will delete the TEST driver from the channel, but don’t be in a hurry, this will not affect the driver installed on your Hub

How to add this devices? I bought a Vallhorn and a Parasoll but can’t seem to add them to smartthings.

That is a very good question. I have bought five Vallhorn and so far I have been unable to use them. The first sensor I tried pairing did actually pair but then I had to delete the sensor I have been unable to repair any of them since.

Pressing the button for 10 seconds does not activate pairing. I have tried this after allowing the sensor to power up and also keeping the button pressed while putting the batteries in. The four presses of the button does not work either. I have tried slow presses, fast presses and everything in between. Nothing.

I have now bought new batteries to try out in case my AAA’s I have here might be a bit low on power. As a last resort, until the new batteries arrive, I am going to put the existing ones in a warm spot in the sun to see if warming them up helps.
