I’m trying to detect when a zigbee sensor stops responding or is unavailable. When that happens the sensor value is sometimes “unavailable”, “N/A” or it remains with the last known value. Since it’s hard to figure this out via sensor value, I’d like to read the “Last Seen” attribute for the device …

Turns out you can do this by using states.sensor.DEVICE.last_updated or .last_changed in a template. For example, I’d get last_changed like this states.sensor.lumi_lumi_sens_57884f03_temperature.last_changed You can also get the other attributes by using .attributes.WHATEVER, like this states.se…

[image] MichaelApproved: For example, I’d get last_changed like this state.sensor.lumi_lumi_sens_57884f03_temperature.last_changed I think you meant states.sensor...... instead of state.sensor... above. Just FYI… Are you doing anything special to access those attributes? Which integration…

Yes, you’re right. It should be states and I updated my previous comment. Thanks! I’m using ZHA with the GoControl Zigbee/ZWave stick . My sensors are the round style of the Xiaomi Mijia temperature and humidity sensors. They connect without too much trouble but my main complaint is the temp won’t u…

This doesn’t seem enough, I’ve opened an issue about: ZHA: Expose last seen date as device (or child sensors) attribute · Issue #58955 · home-assistant/core · GitHub

last_updated or last_changed don’t have the same value as last_seen I would also like to get the last_seen info, in my case to check if smoke detector is still connecting via ZHA. [image]

I’ve created a workaround as I also need the last_seen for determining when zha devices is unavailable and HA needs restart to reactivate device. I’ve created a template sensor from one attribute which I know is updating (most) often: template: - sensor: - name: "Ally TRV demand" u…

I’ve also been looking for a way to detect unresponsive devices for some time so thanks for opening that issue. Unfortunately, the comment that closed that issue doesn’t provide any details about how to access last_seen from any of the “diagnostics entities” it mentions. I have noticed that there …

Your post here was very informative, provided great information. Based on what you wrote, I made a blueprint to scan daily and notify when Zigbee/Zwave battery powered devices have gone offline, (I borrowed heavily from a blueprint from Sybx). Have posted it here

How can I read the "Last Seen" value of Zigbee device?
