The list views in the Console indeed only show a limited set of fields. The reason for this is that The Things Stack has different databases for “cold data” (the metadata you see in the overview) and “hot data” (the state of the devices, that is used for routing). Each of these databases is optimized for its purpose, so the “cold database” is optimized for listing a lot of devices, while the “hot database” is optimized for quickly reading and writing a single device.
While it wouldn’t be too difficult to add a “last seen” to the device list, it would currently be impossible to sort devices by that “last seen” field. So instead of building a half-finished feature, we’d rather wait until we come up with an actually good solution for making this possible.
A “last seen” value in this table would be really great, this came already up in our community in Munich too.
We would be happy if this could be implemented - even without the sorting Feature, which I personally don’t consider that important.
I’m moving some of my utilities over from V2, if you put a WebHook in (you can have as many as you like on an application), it would be easy enough to have a page that picks up the data and presents it as required. Or a desktop app via MQTT.
If this is of interest, I can factor this in to my plans.
