+1 here with false motion detections, depending on the batteries used.
To test I’ve put two vallorns in a dark, closed drawer for >12 hours:
normal Panasonic alkaline batteries → false detections every 5 minutes at voltage ca. 1,6 V
Eneloop rechargable batteries (1,2V 750 mAh) → false detection every 1-2 hours, at voltage 1,299 and 1,300 V
IKEA Ladda HR03 1,2V 900 mAh rechargable batteries → no false detections at all at voltage 1,288 V and 1,299 V
Amazon basic normal 1,2 V 800 mAh rechargable → no false detections at all in 14 hours
The battery indicator shows 60-70 % for rechargable batteries. It is interesting to see that different rechargable batteries produce different fake detection rates even at nearly identical voltage.
According to the manual it appears to be possible:
Good to know Without DIRIGERA, you can connect a maximum of 10 smart products to one motion sensor. Remember to add one product at a time. If your products are close together, disconnect the ones you have already connected while adding the next product

Thought my issue would be fixed with ordering some 1.2v batteries and then I noticed the ones from Ikea are 1.2v themselves so I bought them for nothing
Slightly different story here, the sensors trigger but don’t turn off the lights.
Haven’t set up a HA setup yet and I’m working purely with Dirigera so I have zero logs sadly.
Got me 4 vallhorns and it seems only 1 is working correctly after buying the IKEA 1.2 batteries. The other 3 keep ghosting with false positives. Hoping for OTA firmware upgrades
Similar story here. I have 2. Powered up one initially and got false positives galore after I put standard batteries (that ironically I only use for things like this!)
I read this, and I decided to experiment.
I changed the batteries in the initial unit to rechargeable and put the standard ones in the other, as yet, unopened unit.
Put them both in their boxes on the side…
The original unit that had all false positives, once I changed, not one false positive.
The other device, with the standard batteries IS reporting false positives now. I will change to rechargeables and see if that settles down.
I want to take out of the boxes and ensure the ‘working’ unit does report occupation as expected.
I’d suggest anyone who reads this writes a review on Ikea’s site as I expect more from them.
I was having issues as well, I also tried rechargable Amazons and verified the voltage. It still had issues. I tried the Ladda batteries and still had issues. Then saw someone mentioned that swapping over to a Skyconnect fixed it. I tried it and it fixed it.
I was using a Sonoff dongle, P version with a firmware that was updated several months ago with Zigbee2MQTT. I had issues with the Sonoff motion sensors as well, and some of my other Ikea remotes were hit and miss. Everything has been working flawlessly since trying the Skyconnect with ZHA.
These Valhorns now work nearly as well as the Philips Hue sensors.
My Vallhorn is on the other side of the spectrum, it has false-negatives most of the time. I wish it had a way to adjust the sensitivity. And it’s using the 1,2V IKEA LADDA batteries.
I found out that the batteries with voltage of 1.2 makes it work better. Alkaline batteries are typically 1.5 V and the IKEA rechargeable ones are 1.2V. I wonder if the circuit is made for 1.2V and thus all the problems with higher voltage?
Anyone have any ideas:
i’ve placed ikea lada batteries in the valhorn,
updated z2m to latest version:
i see it communicating:
it’s been in a closed drawer for almost half an hour:
it contact z2m but doesnt report back the end of the detection:
Just wanted to add another comment about the Vallhorn working better with 1.2V batteries.
I picked one up last month, put some normal 1.5V alkalines in it, and it triggered great but the false detections turning a light on were a problem at night.
Went to Costco last night, bought their set of Energizer-brand 1.2V AA / AAA batteries and charger, and set the AAAs up in the Vallhorn. All last night not a single false detection.
I really like this motion sensor, and it’s great to have it not turning on lights in the middle of the night. Maybe now I’ll pick up a couple more to sprinkle elsewhere in the house.
How do you find the motion detection range, positioning and reliability? When I position the vallhorn just below the ceiling, faced slightly downward the way I use my Aqara P1 motion sensors, the vallhorn misses a lot of motion events. When I hang it on a wall, 2 metres above the floor, it works miles better. The Aqara s are still unbeatable regarding instant reaction and accuracy.
The only downside of the Aqaras really is that they take button cell batteries.
Would be interested how you position your Vallhorns. The Vallhorns seem overly bulky so I want to position them as much out of sight as possible
Did you manage to resolve this? I’m having similar issues with a brand new sensor.
This is my first VALLHORN sensor and used it with new LADDA 750 mAh batteries. After pairing the sensor stays on “detected”. The Lux values do update but seem to be all over the place, going form 213 to 2 within 30 seconds whilst nothing changed in the room. I’ve also tried to repair the device trough another router device, rebooting Home Assistant and also another set of rechargeable batteries (LADDA 900 mah) without succes.
I’ve noticed the logbook keeps updating every 30 seconds with:
Bewegingssensor woonkamer Attribute Updated event was fired
11:24:07 PM - Now
Bewegingssensor woonkamer On With Timed Off event was fired with parameters: {‘on_off_control’: <OnOffControl: 0>, ‘on_time’: 600, ‘off_wait_time’: 0}
For what it’s worth, the VALLHORN firmware is 0x01000064 and I’m using Sonoff Zigbee 3.0 USB Dongle Plus V2 (the -E variant) with USB extension cable in combination with ZHA.
Only when I try to repair the device, without deleting it first, I get it to work once. I’ve tried that a couple of times:
