Alarms from zones & hysteresis
I stumbled upon this issue when one of the temperature measurements is bouncing between configured zones and sending excessive amounts of push notifications. See the attached photo (copied from web) which quite clearly describes the case. Usually, such issue has been solved by setting a hysteresis range, for example in case of a temperature measurement it could be from 0°C to 1°C. When T goes down to 0°C, alert is summoned, but in order to clear the alert, T must rise to 1°C or above. I'm sure everyone is aware of this solution.
The question is, how have you solved this, is there perhaps another plugin for triggering notifications or have you sorted it out with Node-RED? Or am I using zones wrong?
