The IKEA PARASOLL is a Matter-compatible door and window sensor using Thread protocol. This guide addresses detection issues and connectivity problems.
Common Symptoms
- Sensor not reporting open/close status in app
- Delayed notifications when door or window opens
- Sensor showing as offline or unavailable
- Automations based on sensor not triggering
- Battery draining faster than expected
Verify Proper Installation
1. Check Magnet Alignment
The sensor relies on proper magnet placement:
- Sensor and magnet should be within 15mm of each other when closed
- Alignment marks on both pieces should face each other
- Use a level to ensure both pieces are straight
- Test by moving magnet near sensor—app should show status change
2. Mounting Surface
Proper mounting ensures reliable detection:
- Clean surface thoroughly before applying adhesive
- For metal door frames, use standoff or mount on wood trim
- Allow adhesive 24 hours to cure before testing
- Consider screw mounting for heavy-use doors
Connectivity Issues
1. Thread Network Status
PARASOLL uses Thread protocol and needs a Thread border router:
- Ensure DIRIGERA hub or compatible Thread border router is online
- Check hub LED status for normal operation
- Thread devices work best with multiple routers forming a mesh
- Add TRADFRI outlets as Thread routers if signal is weak
2. Improve Thread Coverage
If sensor frequently goes offline:
- Add Thread-enabled devices between sensor and hub
- Move DIRIGERA hub to a more central location
- Avoid placing hub in enclosed cabinets or behind TVs
Reset and Re-Pair Sensor
Factory Reset Steps
- Remove sensor from IKEA Home Smart app
- Open the sensor cover to access reset button
- Press and hold the reset button for 5+ seconds
- LED will flash to confirm reset
- Re-add in IKEA Home Smart app > Add device > Sensor
Matter Pairing
For adding to other Matter controllers:
- Ensure sensor is reset and in pairing mode
- Scan the Matter QR code on the device or box
- Follow your controller app's pairing instructions
- Wait for Thread network to establish (may take 2-3 minutes)
Battery Optimization
PARASOLL uses a coin cell battery:
- Use high-quality CR2032 battery for best life
- Expected battery life is 1-2 years with normal use
- Frequent open/close cycles reduce battery faster
- Replace battery when app shows low battery warning
Automation Issues
If automations based on sensor don't trigger:
- Test sensor manually—verify status changes in app
- Check automation conditions are set correctly
- Ensure automation is enabled and not paused
- Verify time-based conditions if used
- Test with a simple automation first
When to Contact Support
Contact IKEA support if:
- Sensor won't enter pairing mode after reset
- Battery drains within weeks of replacement
- LED doesn't light up when triggering sensor
- Physical damage to sensor housing or magnet
