last seen not showing up

[sbcrumb]

What happened

New Install just a few devices and last seen of the bulbs is not being reported.
Availability is set to 60. last seen did prev work in HA on a ZHA with the same devices.

What did you expect to happen

Last seen to been shown on front end and in home assistant.

How to reproduce it (minimal and precise)

Debug info

Zigbee2MQTT version:
Adapter hardware: CircuitSetup CC2652P
Adapter firmware version: Z-Stack 3.x.0 20210708

You need to set last_seen to something that is not disabled

Oh wow I missed that, I feel dumb. So I can just set this to true and should be good?

[sjorge]

  # Optional: Add a last_seen attribute to MQTT messages, contains date/time of last Zigbee message
  # possible values are: disable (default), ISO_8601, ISO_8601_local, epoch (default: disable)
  last_seen: 'disable'

you need to set it to one of the listed values

Ok and is there any difference or does it really just not matter?

[sjorge]

I assume the format would be different, but I’ve never enabled it myself.

Ok picking one seems to have worked. Thank you.

Well, after upgrading til Zigbee2MQTT version 1.22.1 the “last_seen” attribute is showing up as “disabled by the integration”.
It’s possible to enable it in the HA UI, but that is a time-consuming way to update this.
For the “last_seen” attribute it’s not that important for me, but also other attributes are now “disabled by integration”.

I’m using the illuminance attribute, that comes with the “Aqara human body movement and illuminance sensor” (RTCGQ11LM), in a few automations, and they stopped working until I manually enabled the attribute again.

Would be nice if this could be fixed, unfortunately I don’t have the programming skills required to help out with the coding .

Yes same super annoying issue here. Every time I repair my Zigbee network all my devices show up in HA with basic state information, but with many disabled entities. Considering I am conducting many tests of various coordinators I have to redo it on a daily basis.

In particular :
For all devices :
-Last Seen
-Link Quality
-Battery Voltage in Volts (not Battery Level in %)

For Metering Plugs :
-All the above
-Current Drawn
-Voltage
-Outage Memory

So I have to manually edit, enable the entities one by one, then restart HA. Consider 25+ devices time between 3 and 5 entities to manually enable by hand. This is insane ! The entities do have an associated Payload, it's just that for some obscure reason, HA decides that it is not worth enabling them by default. What am I doing wrong here ? Is there a setting in Z2M to force publish these entities with an active state ? Again there is a Payload behind each of these entities. I can see it in Z2M GUI and in my MQTT broker.

I should add that I am using Z2M on a separate Z2M Gateway and so I purely integrate to HA through MQTT messages.

From a fresh newby, I also wondered why 'last seen' was always NA, if it's not configured, maybe do not display this line ?
But even better, why not set this to enabled by default (local time)
Not that it would make any difference in the TCP packet being send to the MQTT broker as the MTU is 1500+ bytes
I think it's a great feature to detect if some sensor is still functional
