Countdown Gauge/Bar ? anyone know of one?

Guys,

I want to create a Status page on my NR dashboard that will keep track of all my different sensors, devices etc and alert me visually if one has not checked in for a period (and also provide a visual indication of how far along until the next check in.

So say i have a node that sends its temperature measurement every 10 minutes, i would like (say) a 10 segment LED bar representation - all of them start out green and then as each minute counts down they fade out. If after 10 minutes the sensor has not been heard from , then they will start to light up RED until all 10 are lit and then messages (emails, Telegram etc) will be sent to warn that a sensor is not communicating.

Anyone seen anything like this ? I would assume it would be some form of angular to be inserted - at this stage that is way above my ability though - so i hope there is an easier answer

Must not have had the right terms when searching before.
