Integral Sensor

[slate rose]

I have set up an integral Helper and it's working fine, but I can't seem to find an equivalent YAML. I would like to be able to copy-paste my config so I don't have to repeatedly duplicate it via the helper UI workflow

Based on the Integral docs I added this to configuration.yaml:
``sensor:

• platform: integration
  source: sensor.live_power_out
  unique_id: energy_int_out
  name: Energy Integral Output
  round: 2
  unit_prefix: k``

That block parses without error, but I can't find an entity or state or statistic related to the sensor - it doesn't seem to do anything

What am I missing? Is there a better or more modern way to define an integral sensor in YAML?

might need some data input to get it to show up

I can see updates to the source ticking in and the Helper version of the same integral has valid values

This is the releated Helper config that is working:
{"created_at":"2025-09-27T19:24:56.595720+00:00","data":{},"disabled_by":null,"discovery_keys":{},"domain":"integration","entry_id":"01K66A5CCK7WCDQTH5BS0H6CV1","minor_version":2,"modified_at":"2025-09-27T20:50:14.716247+00:00","options":{"max_sub_interval":{"hours":0,"minutes":5,"seconds":0},"method":"trapezoidal","name":"nrg_sum_out","round":2.0,"source":"sensor.live_power_out","unit_prefix":"k","unit_time":"h"},"pref_disable_new_entities":false,"pref_disable_polling":false,"source":"user","subentries":[],"title":"nrg_sum_out","unique_id":null,"version":1},

you might have to do a full core restart

yellow option. My config defined sensors dont show up unless I do that.

That seems to have worked

I tried a full YAML reload several times, which is sufficient to refresh template sensors but apparently not enough for regular sensors. Having to lose state on everything to add sensors is a little annoying, but I’m glad it works

Thanks a bunch for your help

Hot reload only works if an integration is already loaded.

Now that you have one integral sensor, any further ones you add can be hot reloaded.

Full restart always needed for adding the first instance of any type of sensor.

Okay. That makes sense. Thanks for explaining

[crisp pilot]

Actually looking at the code I'm not sure if integration has a reload service 🤔

That's generally the rule, but some integrations don't support reload. Maybe integral is one of them.

[weary bay]

I tried that, didnt work for me

[crisp pilot]

Yeah I was wrong. It just doesn't reload.
