Homey CountDown timer

This is a CountDown timer which you can use to initiate flows.

Examples: When motion is detected, turn on light and start a timer for 90 seconds After 11 seconds, when motion is detected again, restart the timer for 90 seconds When the timer reaches 0, there was no motion for 90 seconds, turn off the light.

Settings

After installing the application, you can create CountDown timers in a flow.

In the app settings of CountDown, you can also add, remove, import and export timers.

If you see a value '-1', this means the countdown timer is not active and waiting to be set ( via an action card in the flow )

Triggers

- When a CountDown timer reaches 0. This will be the most used trigger.

- When a CountDown timer has changed its value
- When a CountDown timer has started or updated.

Conditions

There are 4 condition cards:

• Timer is (not) running: check whether a timer is running (or not)
• Timer is (not) exactly value: to be used in combination with the 'value changed' trigger card. You can use this to check if a CountDown timer has reached a certain value.
• Timer is less/greater than: check if a CountDown timer has a value less/greater than a specified value
• Timer is (not) paused: check if a timer is paused
