hallo, i would like to receive a notification once one or more entity will become unavailable, but i cannot figure out which is the easy way .
I am able to create an automation that notify me if the “sensor_status” wifi rssi become “unavailable” but to do this for 100 sensors i should create 100 automations .
is there a way to select “all the entities” in one automation ?
for example “select all the *.status” entities , then if some sensors goes offline the status become unavailable and i will get a notification …
I already tried with Groups, but the “status” is not supported, they accept only on and off to switch a group .
