Gemini Automations: Do They Work Locked or Offline?

Yes, Gemini automations can run when your phone is locked, but they generally do not work when your phone is fully offline. The key distinction is that automations are processed on Google’s servers, not on your device, so they need an internet connection to trigger and execute, but they don’t require your screen to be on or the app to be open.

What Are Gemini Automations?

Gemini automations are a feature within the Google Gemini app (formerly Google Assistant) that let you create custom voice or text commands to trigger a sequence of actions. For example, you could say, “Hey Gemini, good morning” and have it turn on your smart lights, read your calendar, and play the news. These are built using the “Routines” feature or the newer “Gemini Extensions” that connect to third-party apps like Spotify, WhatsApp, or your smart home devices.

Unlike simple one-off commands, automations are designed to be multi-step and can include conditions (like time of day) and actions across multiple apps. They are stored and executed in the cloud, which is why they behave differently when your phone is locked or offline.

How Automations Work When Your Phone Is Locked

When your phone is locked, Gemini automations generally work as long as the phone is connected to the internet and has “Hey Google” or “Hey Gemini” voice detection enabled. The process works like this:

• Your phone’s microphone listens for the wake phrase, even when the screen is off.
• Once the wake phrase is detected, the phone sends your voice command to Google’s servers.
• The servers parse the command, match it to your automation, and send back instructions to your phone and any connected smart devices.
• The phone executes the actions, such as playing media, sending a message, or controlling smart home gadgets.

However, there are some caveats. If your phone is locked and you have a PIN or pattern set, certain actions that require authentication (like reading personal messages or making payments) may be blocked. Google’s default is to require the phone to be unlocked for sensitive actions, but you can change this in the Assistant settings under “Personal results” or “Lock screen” settings. For most non-sensitive automations (like turning on lights or playing music), the phone can stay locked.

Do Automations Work When Your Phone Is Offline?

No, Gemini automations do not work when your phone is completely offline. Since the automation logic and the connections to third-party services are handled by Google’s servers, an internet connection is required. If you’re on a plane in airplane mode or in a remote area with no cellular or Wi-Fi signal, saying “Hey Gemini” will either not respond or will respond with an error like “You’re offline.”

There is one partial exception: some very basic commands that are handled entirely on-device, like setting a timer or turning on the flashlight, may work offline because they don’t require cloud processing. But these are not automations in the full sense—they are simple local actions. Any automation that involves multiple steps, smart home devices, or third-party apps will fail without an internet connection.

How to Set Up Automations That Work While Locked

To ensure your automations run smoothly when your phone is locked, follow these steps:

1. Open the Google app or Gemini app on your Android phone.
2. Go to Settings > Google Assistant > Routines (or the equivalent in Gemini).
3. Create a new routine or edit an existing one.
4. Make sure the trigger phrase is something you’ll say out loud, like “Hey Google, good morning.”
5. Add actions that do not require unlocking, such as smart home controls, playing music, or getting weather updates.
6. In the Assistant settings, enable “Personal results” on the lock screen if you want calendar or message previews to show.
7. Test the routine by locking your phone and saying the trigger phrase.

Note that on some phones, battery optimization settings can interfere with voice detection when the screen is off. Make sure the Google app is not being aggressively killed in the background.

Common Problems and Limitations

Users often run into a few common issues when using automations:

• Wake phrase not working when locked: This is usually due to battery saver mode or the “Hey Google” detection being turned off. Check the Voice Match settings.
• Automation runs but some actions fail: For example, if the automation tries to send a text message, the phone may require unlocking. You can change this in the Assistant’s “Personal results” settings.
• Smart home devices not responding: This is often a network issue—your phone and the smart devices need to be on the same network, and the devices themselves need to be online.
• Automations not triggering at all: If you scheduled an automation (e.g., “every day at 7 AM”), it may not run if the phone is off or in airplane mode at that time. The phone needs to be on and connected to the internet.

Gemini vs. Siri and Alexa: Offline Behavior

Comparing Gemini to other assistants helps clarify what’s normal. Siri on iPhone can handle some offline commands like setting timers, but most Siri requests also require an internet connection. Alexa on Echo devices is entirely cloud-based, so it also fails offline. The main difference is that Gemini and Siri have some on-device processing for simple tasks, but automations are not among them. If offline automation is a critical need, you might consider using a dedicated home automation hub like Home Assistant, which can run locally without internet, but that requires more technical setup.

Frequently Asked Questions

Can I run Gemini automations with the screen off?

Yes, as long as the phone is locked but not off, and the “Hey Google” detection is enabled, automations can run with the screen off. The phone will wake up briefly to process the command.

Why does my automation only work when the phone is unlocked?

This is usually because the automation includes a sensitive action like reading notifications or sending messages. You can change this by going to Assistant settings > Lock screen and enabling “Personal results.” Keep in mind this may reduce security.

Will Gemini automations work in airplane mode?

No. Airplane mode disables all wireless communication, so the phone cannot reach Google’s servers. Simple local commands like setting an alarm might work, but full automations will not.

Do Gemini automations work on iPhones?

Yes, the Google Assistant app is available on iOS, and you can create routines in the Google app. However, some actions that rely on deep Android integration (like changing system settings) may not work on iPhone.

Can I use Gemini automations without saying “Hey Google”?

Yes, you can trigger automations manually by tapping the Assistant icon or using a shortcut on your home screen. You can also schedule automations to run at specific times without any voice trigger.

What happens if I lose internet connection mid-automation?

If the automation has already started and the connection drops, the actions that have already been sent to devices or apps may still execute, but any pending actions will fail. The automation will not resume once the connection is restored.
