Zigbee2mqtt dashboard shows ‘last seen’ for each device.

However, I don’t see ‘last seen’ as a sensor/entity property. All I see is the following:

  - entity: sensor.aqara_outdoor_temperature
  - entity: sensor.aqara_outdoor_humidity
  - entity: sensor.aqara_outdoor_pressure
  - entity: sensor.aqara_outdoor_battery

How do I add/enable the ‘last seen’ property?

Thanks

After some digging, I figured out that ‘last_seen’, as well as ‘link_quality’, are attributes that are disabled. After enabling them, now I can see them on dashboards.

Were you able to enable them?

You can easily enable it by following this path: Zigbee2MQTT → Settings → Availability → Availability (Advanced)

Did anyone find how to enable the last_seen entity by default?
I just enabled 100+ entities one-by-one.

In z2m configuration.yaml:

device_options:
  homeassistant:
    last_seen:
      enabled_by_default: true

For some extra info. To be able to enable the “last_seen” attribute of existing devices, you will need to rename the sensor in Z2M to force a regeneration in Home Assistant and then rename it back to it’s original name.

I just enabled last_seen.enabled_by_default in Z2M and enabled last_seen entities. Worked flawlessly.
