WristWake is an alarm app for the Pebble Time 2 that syncs your alarms with Home Assistant. This lets you, for example, turn on the lights or start the coffee machine when your alarm rings. WristWake connects to your Home Assistant instance with a long-lived access token. The token is used only once to register your watch and is then discarded. It is never stored. After that, all updates are sent via webhook.

I love waking up to the vibration of my Pebble on my wrist. The native Android alarm app can sync its alarms with Home Assistant through the Home Assistant Companion App. With a Pebble, however, there was no way to pass my alarms on to Home Assistant to trigger automations or other actions. WristWake bridges this gap.

In Home Assistant, your watch appears as its own device. It reports whether an alarm is ringing, snoozed or dismissed, and shows all alarms with their settings.

For the darkness color scheme by sunrise and sunset, WristWake uses the approximate location of your phone. It stays on the phone; the watch only receives the sunrise and sunset times.

I designed the concept, the features and the look of this watchapp myself, down to the menu items, ringtones and vibration patterns. For the coding, I used Claude Code.
