Here’s some example flows

>
> Zone Activity Controlled Light / Device To prevent the light (or other device) from turning off (or on), while there’s still motion detected. It uses Homey’s Zone Activity AND a timer. This way your motion- & contactsensors become exchangeable and expandable, without having to fix the flow. This way, you can add a sensor, remove one (use 1 sensor minimum), use one with another protocol (f.i. zigbee/wifi/z-wave) in a zone. Apps used [Chronograph](https://homey.app/a/nl.fellownet.chronograph/)Flow example:

> [@The Flow Exchange(r) - Exchange Your Flows with Others!](https://community.homey.app/t/the-flow-exchange-r-exchange-your-flows-with-others/68981/26):
>
> Motion and Presence activated Light/Device with Sunset condition This flow triggers a light when a motion sensor triggers, or a person enters the home location. With both events, the light turns off after 5 minutes, IF there’s no motion detected in the mean time.
