The Lumo Lift Sensor is meant to vibrate when the user is slouching or has deviated from the target posture that was calibrated by the user. If the Lift Sensor does not vibrate (i.e. buzz) when the user is in bad posture, please use the recommended steps below to troubleshoot the problem:
- Confirm that the sensor is charged fully. If the LED doesn’t flash green when the sensor button is pressed, charge the sensor.
- Confirm that the sensor vibrates when the button is pressed. If it doesn’t, try a cradle reset: Place the sensor in the charging cradle, with the cradle connected to a USB power source (e.g. a USB port on a laptop, or a USB charging block). With the sensor in the cradle, press and hold the sensor button for 15-20 seconds or until the device LED flashes blue/ purple and vibrates once.
- Check the Posture Feedback Delay setting. If this value is set too high, you won’t get many posture feedback vibrations. Just to be clear, if the delay is set to 60 seconds, the sensor will not vibrate until you have been out of good posture for a continuous period of 60 seconds. For troubleshooting purposes, select 3 or 5 seconds. (Android: tap the menu icon on the top left -> select Posture Feedback Delay -> select a low value.)
- Get into good posture, press the sensor button once to set the target posture, then slouch for longer than the delay setting used above. Does the sensor vibrate?
- Try toggling Posture Feedback OFF and back ON. Slouch for longer than the delay setting used above. Does the sensor vibrate?
- If the sensor is charged and responds to a button press, and the sensor doesn’t provide feedback when you slouch, the issue may be because of the way the sensor is worn. Try the tips below:
- Please wear the Lumo Lift next to your collarbone, about an half-an-inch to an inch below it, mid-way between tip of shoulder and your neck. For exceptions to that rule, please see the note below.
- Please wear the Lumo Lift with snug-fitting clothes. Loose clothes cause inaccurate readings because the Lift ends up tracking your garment instead of your body. If you tend to wear loose-fitting clothes, we would suggest raising the placement of the Lift to be perched on top of the collarbone or just above it - to the point where it's sitting in a place on the garment that has less slack, and so follows your body posture, better.
Calibrate your Lift sensor often: The main reason for inaccurate buzzing or lack of accurate buzzing is lack of alignment. You MUST align your Lumo Lift several times a day to get the best out of your Lift. When? Basically, every time you enter into a posture you suspect you will be in, for a while.
- Examples: just put on the Lift after getting dressed in the morning? Press the Lift sensor against your body to align (a triple buzz confirms that the button was pressed). First time in your office chair in the morning? Sit in good posture and press the sensor against your body to align. In a meeting room for 2 hours? Sit straight - and press the sensor against your body to align. Just sitting down after your daily chores? Sit straight - and press the sensor against your body to align.
About the posture feedback delay:
In general, you want the delay to be set to 5, 10, or 15 seconds in the first few days of operation. Setting a shorter delay helps effect change on your current posture habits. After you've acquired desirable posture habits, you can always adjust the Posture Feedback Delay to 45 or 60 seconds, but we would not recommend going above that. The idea is to get your Lift to buzz so it can help you change your current posture habits. And when it's set for too high, the sensor won’t provide feedback and you’ll not get the best out of your Lift.
About turning posture feedback OFF or ON from the sensor:
You can always turn posture feedback OFF or ON from the sensor by pressing and holding it for 5 seconds against your body - 2 buzzes mean it's OFF, 1 buzz means it's ON. (Turning posture feedback off/on from the sensor requires first enabling this feature via Settings -> Advanced Settings -> Use Sensor to Turn Feedback On/Off.)
