The ‘No Motion’ trigger does not work as a standalone timer that can activate “out of nowhere.” Without that initial motion,the automation would have no valid starting point. In practice, this could cause it to fire immediately and repeatedly, or at random intervals, in an illogical loop. For example, it might endlessly trigger actions like turning a light or fan on and off.

If you want the light to automatically turn off when it is turned on by other means, create separate automation rules for those actions.

To clarify, this device is a PIR motion sensor. This means it only triggers and reports a detection when its built-in sensor physically detects movement, which then activates any linked software functions or automations.

How would you like to trigger it? If your goal is to trigger events on-demand or to control when the sensor reports motion via software commands, that’s not how a PIR sensor works. You can’t tell it when to trigger.

For that kind of on-demand control, you could use an idle or spare device as a “virtual trigger.” You’re not actually trying to control that device itself—instead, you’re using its ability to change states (like turning it on or off in the app) to start your automation.

For example, you could set up a smart plug as the trigger in your automation. Then, whenever you want to run the automation, you simply turn that plug on or off using the app or a schedule. That action will trigger the automation to run.
