Steve, the V3 metrics framework has staleness for every metric. You can query the staleness by the command "metrics list -s". Values aren't supposed to disappear/clear when becoming stale. The "live" indicator on the App is showing if the App has received any update recently (i.e. within the last minute). It doesn't indicate that update had new values, just that the connection to the car is alive. Regarding value staleness, the V2 protocol (which the Apps still use and probably will continue to use, as it's much more efficient than MQTT) only has support for staleness info on a handful of values, mostly the temperature readings. Those get grey when becoming stale. See https://docs.openvehicles.com/en/latest/protocol_v2/index.html for the protocol details. You can add some more staleness info to the V2 message protocol quite easily, and adding support for greying out the values in the App also isn't hard. Add new data to messages at the end for compatibility. Think about which staleness actually matters. Up to now, the staleness indication for temperatures has been sufficient, as these also indicate general staleness. If you plan to add data to the V2 protocol, it's probably best to discuss that first here. The web UI currently doesn't care about staleness. If you miss that info, it isn't hard to add as well, just a bit of work to connect the dots. Regards, Michael Am 26.12.20 um 16:00 schrieb Steve Davies:

If the car is off and not responding on OBD then obviously information going through to the apps becomes stale.
But the apps still show "Live" in the corner and it's not obvious that the info is out of date.
Is there a way to show how many minutes old the data is or something like that?
Does this interact with the autostale stuff in some way? I'm not really understand the effect of this - I changed the metrics for 12v current to SM_STALE_MID and it must be stale by now but the misleading 8.9A figure is still showing in the OVMS web "status" page. Also in "metrics list". Is it supposed to disappear when it goes stale.
Thanks, Steve
