Any way to detect a rogue sensor?

Configuration
1

Sometimes one of my GSM/SIM card sensors goes rogue (due to a loose connection that’s complicated to fix, will get round to it…) and publishes extremely frequent state changes. This is both annoying and uses up valuable/expensive data. It also pollutes my HA log db etc.
Is there any way (other than setting lots of timers and spider’s web if,if,if logic) that I can detect a sensor which is sending “too frequent” state changes? I could then
a) disregard the state changes
b) notify myself that the sensor has gone rogue
c) remotely disable it

thanks!!

I think the throttle section of the filter sensor may help

Thanks, but not sure it will, unless I’m misunderstanding something. Looks like that would be useful if a sensor sends too much bona fide data - in this case it’s when my sensor is sending very frequent updates that I know something’s gone pear shaped.

Something like what @arsaboo is doing here might be the answer, but I’m not sure if I’d need to create lots of extra binary sensors and timers for the sensor which seems excessive - if there’s a simpler way
