I have a bunch of rtl_433 devices showing up in Mosquitto broker but when I add them to dashboard and see when was the last signal received, for some of them it is >24h which is obviously not normal.
So the question is - how do I define a new dashboard which will be populated only with the devices where the last reported time is >24h? Devices which re-report again, should be automatically removed from the dashboard - only non-reporting (after a certain time) devices should be there.
THe next step would be to automatically remove devices which have not been reporting their status for >72h.
Thanks in advance.
