proper hinge
I can't get my brains around this, I'm not that strong in templating yet, nor defining custom/virtual sensors. If anyone wants to take it as a challenge, here is what I'm looking for:
A virtual sensor that can count all events from all my sensors and devices, and calculate a minute average, so that I can both see at which times of day my house is the most chatty, and also to serve as a fun tile on my dashboard

template:
- trigger:
- platform: event
event_type: "*"
sensor:
- name: "events fired"
state: "{{ (states('sensor.events_fired')| int(0)) + (0 if trigger.event.data.entity_id == 'sensor.events_fired' else 1) }}"
unit_of_measurement: "1"```That will give you an increasing number

Ooh, excitement!
So when you only provide a name for a sensor, the id becomes that name in lowercase with underscores? I have a few million events already, I think it counts itself
safe wraith
Yes, that's how the name works. And you need to update the template so it filters itself out.

It is still decimating the performance of HASS currently. I did a straight copy/paste
template:
- trigger:
- platform: event
event_type: "*"
filters:
- not:
trigger.event.data.entity_id: 'sensor.events_fired'
sensor:
- name: "events fired"
state: "{{ (states('sensor.events_fired')| int(0)) + (0 if trigger.event.data.entity_id == 'sensor.events_fired' else 1) }}"
unit_of_measurement: "1"
Something like this?
Yikes, it is dead, we killed HASS!

I don't think filters exist on event triggers. It's not in the documentation.
proper hinge
aah, it's on the template itself?
safe wraith
That's what the (0 if trigger.event.data.entity_id == 'sensor.events_fired' else 1) part does
So make sure that's your actual entity id
proper hinge
I believe that didn't work then, it quickly spun up to millions of events, and made HASS completely unresponsive
ok, forget that it DID work, what created the millions of events was when I added a Riemann helper to group those counts into minutes. Hmm.. Isn't there a filter that I can add to reset the counter every minute, i.e. a sliding window?
safe wraith
state: "{{ (states('sensor.events_fired')| int(0)) + (0 if trigger.event.data.entity_id in ['sensor.events_fired', 'sensor.your_riemann_sensor', 'sensor.anything_else_you_do_not_want_to_count'] else 1) }}"
proper hinge
Aah!
safe wraith
That could work
proper hinge
It DOES work, however, one remaining thing:
The counter only increases, so the riemann average only goes up. Ideally, I'd reset the count every minute..
safe wraith
Maybe you could try the utility meter instead?
