The gas sensor gives false alarms or never alarms

Too many alarms

• Cooking, spray, alcohol, cleaning products also change the sensor. Do not put it right next to the cooker.
• A new sensor needs about a day to settle.
• Re-calibrate in fresh air with one short press on the BOOT button.
• Raise the alarm level (default 300 ppm) a little.

No alarm when you expected one

• Is the sensor online? See A circuit shows offline.
• Is the alarm level too high for what you tried? Lower it in More → Rooms.
• Does your account see the room? Alerts go to the house admins and to people who may see the room.
• The sensor must have warmed up (90 seconds after power-on).

Careful: This sensor is a convenience alert and not a certified detector. Use certified detectors for safety.
