$8 – $15
Budget Zigbee motion sensor with IP44 rating for bathroom use, controls up to 10 IKEA smart lights.
You need simple no-hub motion-activated lights
Works directly with IKEA TRADFRI bulbs without gateway. Battery powered. Good for basic automation.
You want Zigbee sensor for Home Assistant/SmartThings
Standard Zigbee protocol. Works with ZHA, Zigbee2MQTT, SmartThings, Hubitat. Affordable multi-hub option.
You already use IKEA smart home ecosystem
Native integration with TRADFRI/Dirigera. Works with IKEA gateway for HomeKit. Standard Zigbee for other hubs.
You want the cheapest motion sensor for IKEA lights
Can control IKEA TRADFRI lights directly without any hub. Simple motion-triggered lights out of box. Very affordable.
You need light level sensing
No lux sensor. Cannot distinguish day/night. May turn on lights in daylight. Consider newer VALLHORN instead.
You need quick reset time between detections
2-3 minute cooldown period. Cannot detect motion again for minutes. Not adjustable. Too slow for many uses.
You need reliable connection over time
Reports of sensors losing connection every few days. May need frequent re-pairing. Connection stability issues.
Sensors lose connection every few days. Need to re-pair frequently. Zigbee mesh issues suspected.
Home Assistant CommunitySensor never detects motion even after reinstalling and reconnecting multiple times. Pairing issues common.
SmartThings CommunitySensor stops giving correct status. Stays on motion alarm even when no motion present.
Homey Community2-3 minute cooldown after motion detected. Cannot detect again until reset. Not configurable.
Multiple ForumsVery long 2-3 minute cooldown between detections
widespreadCause: Firmware design. Cannot be adjusted. Pre-defined timeout not configurable.
No light sensor (lux) for day/night detection
widespreadCause: Hardware limitation. Turns on lights even in daylight. Newer VALLHORN has lux sensor.
Sensor loses Zigbee connection frequently
commonCause: Zigbee mesh issues or sensor firmware. May need re-pairing every few days.
Pairing failures with non-IKEA hubs
occasionalCause: Zigbee compatibility issues. Works better with IKEA gateway than third-party hubs.
Inconsistent motion detection
occasionalCause: Sometimes misses motion. May work fine initially then become unreliable.
Expecting quick motion reset time
Lights turn off and stay off for 2-3 minutes even with continued motion.
Tip: Understand 2-3 minute cooldown is fixed. Consider Aqara with adjustable timeout.
Using without realizing no lux sensor
Lights turn on during daytime wasting energy. No automatic day/night behavior.
Tip: Use smart hub rules to add time/light conditions. Or upgrade to VALLHORN with lux sensor.
Expecting reliable connection with non-IKEA hub
Sensor drops off Zigbee network. Needs frequent re-pairing.
Tip: Place sensor close to Zigbee coordinator. Add router devices. Use IKEA gateway for best results.
IKEA Home Smart app features. Remote access. HomeKit may work locally with gateway.
Direct bulb control works locally. Zigbee communication is local. No cloud needed for basic function.
Motion events. Minimal with local Zigbee use. IKEA cloud if using their app.
Simple PIR sensor. No audio/video. Can be fully local with third-party Zigbee hub.
Tested with up to 50 devices
2x CR2032 batteries (~6 months). Standard Zigbee. Works directly with IKEA bulbs. 2-3 minute cooldown.

You want cheapest Zigbee motion sensor
Very affordable. Works with Home Assistant, SmartThings. Accept limitations for price.
You just want simple IKEA light automation without hub
Cheapest way to get motion-activated IKEA lights. Works directly with bulbs. No setup needed.
You need configurable timeout or lux sensing
Fixed 2-3 minute timeout. No light sensor. Get VALLHORN or Aqara instead.
You need reliable long-term Zigbee connection
Connection drops reported frequently. Consider Aqara or Philips Hue for reliability.
Two CR2032 batteries last approximately 6 months. Fairly decent for motion sensor in this price range.
