Q: My Zen LED's have gone dark. Did they fail?

A: Zen (and Touch) sensors contain a new “Tap” feature to adjust the brightness of the LED’s. Double tapping the sensor will cycle the LED’s through the different brightness settings, so try double tapping the sensor and you should find the LED’s come back to life.

We will work on improving this feature to avoid unintentional changes to the brightness, like with someone walking on the deck nearby the sensor.
