Last Active Times

[GrizzlyAK]

As far as I know, there is no way to know in HA what the value of Last Active in the rightmost column of the CP is for a particular device. The last_updated and last_changed state object properties are lacking if you want to know if a battery powered device has checked in without it actually reporting a change.

I'm assuming that this Last Active includes these "check in" times, as well as any other communication with a device, including reports. I don't expect it will ever be state property of a device, but perhaps it could be retrieved with a service call to fetch the value from zwave-js? Maybe it's possible now, idk. But for checking if a battery device is dead, especially for someone like me who has them set to wake up every 2 hours, it would be extremely useful data. I've found that only a small percentage of my battery powered devices actually report battery levels correctly. I've had some reporting as high as 90%, even though completely dead and the device inoperable. Only one or two have EVER shown 0% when they quit working. It seems the only real way to know is to see if it checks in.

@GrizzlyAK The last seen and last updated time in nodes and values are managed on z2m side (nont from zwavejs driver) so I dunno what you mean here as I dunno how hass handles them. About the wrong battery reports I dunno how this could be improved, maybe a priodic call to refreshValue or pollValue (with an high timeout) could be a possible fix but I let @AlCalzone answer to this

[robertsLando]

Yeah

See: https://github.com/zwave-js/zwave-js-ui/blob/master/lib/ZwaveClient.ts#L4242

I update it when I receive a stats update from node that indicates I received a packet from it

Is that 'last active' attribute from the control panel passed through to the HA integration (via WS) in any way that we can try to access inside HA?

I don't know, I just pass to the websocket the driver instance and nothing else so I dunno what kind information they pass to HA integration. This is a question to ask in HA core repo

I'll go and ask...!

[AlCalzone]

Yeah

so it isn't exposed via zwave-js-server then.

[robertsLando]

Yeah dunno BTW if they do something similar on their side too
