Google Home Jewish Calendar

Turn halachic time into Google Home automations.

This integration creates a smart-home sensor that flips on when issur melacha is in effect and flips off when it ends. That gives you a clean automation trigger for Shabbos and Yom Tov.

Set your location once, choose whether you're in Israel or the Diaspora, link the integration in Google Home, and build routines around the sensor state.

Project overview

What this integration is for

Google Home has strong automation support, but it does not natively expose halachic state such as “Shabbos is active right now.” This project fills that gap by publishing a boolean smart-home device state that Google Home can use in automations.

  • One sensor, two transitions. The sensor turns on when melacha becomes prohibited and turns off when it becomes permitted again.
  • Location-aware. Zmanim depend on your exact coordinates, timezone, and whether you follow Israel or Diaspora holiday timing.
  • Google Home friendly. Once linked, the sensor can be used inside Google Home household automations.
Before Shabbos atmosphere

Dim hallway lights, pause noisy devices, and switch displays to a calmer scene when the sensor turns on.

Motzaei Shabbos reset

Restore regular lighting schedules or send a spoken announcement when the sensor turns off.

Holiday-aware scenes

Use the same state for Yom Tov without building a separate calendar automation flow.

Gentle reminders

Trigger a household routine that changes lighting or runs a custom action when the state changes.

How to use it

Google Home automation tutorial

The current Google guidance uses the Google Home Automations tab and the newer automation editor for household automations. Use this sensor as the starter, then add the actions you want your home to take.

  1. 1. Link the integration. Sign in here, save your location, then link the service in Google Home so the sensor appears in your home.
  2. 2. Open Google Home and tap Automations. Create a new household automation from the Automations tab.
  3. 3. Add a device-based starter. Choose this integration’s Shabbos status sensor and use its state change as the trigger.
  4. 4. Pick the direction you want. Use the sensor turning on for “Shabbos or Yom Tov just started” and turning off for “it just ended.”
  5. 5. Add actions. Turn devices on or off, launch scenes, make announcements, or chain other Home actions.
  6. 6. Save and test. After linking or changing your location, unlink and relink if Google Home does not immediately refresh the device state.
Best practice: treat these automations as convenience features only. Google’s own docs warn that home automations can fail because they depend on internet, Wi-Fi, and third-party availability.

Starter ideas you can copy

  • Shabbos begins: when the sensor turns on, turn off selected smart plugs, dim entry lights, and send a “Good Shabbos” announcement to a Nest speaker.
  • Motzaei Shabbos: when the sensor turns off, restore your weekday lighting scene or turn a laundry room plug back on.
  • Erev Yom Tov prep: use the same “sensor turns on” trigger to warm up lights in the dining room and kitchen.
  • Household quiet mode: use the sensor state as a condition so certain automations only run when Shabbos is not active.
