Send warning only once? #392

Closed janolov closed 4 years ago

janolov commented 4 years ago

Is it possible to trigger an alarm only once when the value of a temp probe passes a predefined value, the alarm should also reset when the temp is correct again and ready to trigger the next time it gets out of bound?

Dear @janolov,

you might want to look at the question raised by @jpduyx outlined within #361 and my answer at Data-loss monitoring with mqttwarn.

In general, advanced alarming and notification features like you are asking for are implemented by more sophisticated monitoring systems like Checkmk or Icinga2.

Also things like flapping are usually taken into consideration when looking at those aspects. Here, you want to implement the behavior you are outlining but want to suppress flapping sensors to send out notifications each time when they trigger through reaching configured threshold values. See also [1,2].

However, #194 implements aspects of what you are asking for to the maximum level what is general sensible to expect from mqttwarn.

With kind regards, Andreas.
