@agx @purism Nice! Could that be used to signal different things using different light characteristics, like blinking slowly means "new email" and blinking quickly means "new sms"? Could be useful to get a quiet hint about what is happening while still leaving the screen off until the user turns it on.
@eliasr @purism sure, that's what we have #feedbackd for. See the event-naming-spec (https://source.puri.sm/Librem5/feedbackd/-/blob/master/Event-naming-spec-0.0.0.md#standard-event-names) and what it maps to in #feedbackd: https://source.puri.sm/guido.gunther/feedbackd/-/blob/leds/data/default.json#L133
