Automation for temp sensor not responded for x minutes?

[Gandarf]

Hi,

Looked around for a solution, but did not find anything.

What do I want to do is:
If a temperature sensor did not update its temperature for more then x minutes, I need to get a notification.

There does not seem to be a property that has the last updated value of the sensor, so I have no idea how to solve this.

Is there a simple solution for this problem?

I have multiple temperature sensors (rfxcom and Bluetooth) that need to notify me if not updated for different amount of minutes, so I can fix the sensor response. This is not related to battery problems, most of the time there is some obstacle blocking the signal of the sensor and somebody needs to move there car

Thanks,
Mark

It’s called last_updated.

Looked around for a solution, but did not find anything.

There’s an example here demonstrating how to periodically poll for sensors that haven’t been updated in X hours (you can adjust the time period to whatever you prefer).

Polling Devices to Avoid Silent Failure

Paste this template into the Template Editor. It will list all sensors whose states have not changed in the past hour (3600 seconds, change it to whatever duration you prefer). {{ states.sensor | selectattr('last_changed', 'lt', now()-timedelta(seconds=3600)) | map(attribute='entity_id') | join(', ') }} You can use that as a starting point to create a template that checks for ‘stale’ entities. If you want it to check sensors and binary_sensors, use expand(). {{ expand(states.sensor, …

Let me know if you need help adapting it for your application.

Thanks Taras, will have a look if this will work.
