# Sensor (or any device) Connection Check.

Sometimes, you’ll discover a sensor or other device doesn’t report it’s status or value anymore, **but it does NOT notify you of being offline…**

Well, this flow checks the, most recent update time of your sensors.  
You can run the flow every day, twice a day, just add or remove a time triggercard.  
The ‘inactive time’ can be edited as well (24hrs as default) and you can choose to _not send notifications_ when all sensors did report inside the ‘inactive timer’ timeframe.

### Apps used:

- [HomeyScript](https://homey.app/a/com.athom.homeyscript/)
- (optional) [Simple (Sys) Log](https://homey.app/a/nl.nielsdeklerk.log)

- For now, in the imported flow, you’ll have to replace the ‘dummy’ DeviceCapabilities cards with HomeyScript _THEN_ card “`Run 'CODE' _with ARGUMENT_, and return 'TEXT-TAG'`”.  
But first copy the script inside them:

- 
  - use CTRL+A and then CTRL+C,

- 
  - to paste it later on, use CTRL+A and then CTRL+V in the HomeyScript card.
