Google Assistant is rolling out a Scheduled Actions.
While Google Assistant already has the ability to turn lights on and off, users will now be able to schedule actions for a variety of smart home gadgets. The support page clarifies that Google Assistant can have trouble recognising temporal adverbs (tomorrow or next week, for example) and users will have to specify the exact date and time when scheduling a command. Google Assistant is rolling out a Scheduled Actions feature that will let users schedule a smart home command to trigger at a later time. You can reportedly also specify a duration for the action, such as "turn on the light for five minutes." As per Google, commands can be scheduled for any day within a seven-day period. Google returns a list of the user's scheduled actions and prompts the user to specify the ones they want to cancel. Users will also be able to cancel a scheduled action, as noted by Google's support page. For example, you can say, “Hey Google, turn on the lights in five minutes” to control your smart lights.
