Home assistant: add more data to the long term statistics

[krusta4711]

Historical data in home assistant is purged after 10 days unless a sensor has defined the attribute state_class. At present ism7mqtt only treads temperatures and percentages as valuable for the home assistant long term statistics. Only for "°C" and "%" the state_class will be send.

I think nearly all values are important to have them long term to be able to compare certain situations. So I added a few more units in this PR: #126

Other user might think different and do not want to have the data long term. So it should maybe even be configurable per unit.

THE CHANGE IS NOT TESTED YET as due to my other long running test which I do not want to stop at present (#115 ). So the PR cannot be merged. Would be good if someone could test whether it works or whether it at least do no harm. ;-)

One day after I changed the code, suddenly enabling the long term statistic in home assistant via customize entry works. 8-P

I was not able to enable LTS via customize before. So I started changing the code. But now it works.

So the code changes I did are not needed right now. Nevertheless for long term it might be the better way to be able to control LTS via ism7mqtt rather than customize. To use customize seems not to be a preferred way by the home assistant developrs.

I don't understand the steps (because being newbe) you did to gain LTS with "customize entry".
Did you change the definitions in develloper tools / states per each entity ?

I would like to have LTS for wolf_cha_0x3_270049_leistungsaufnahme_wp_ehz. The States View only shows
unit_of_measurement: kW friendly_name: Wolf CHA Leistungsaufnahme (WP + EHZ)

There ist no
state_class: measurement

[krusta4711]

Yes, exactly. The state class is not set by ism7mqtt for several units and therefore you need to add it via customize: section if you like to have them in the longterm statistic. E.g. by adding to the customize.yaml:

sensor.wolf_wp_cha_0x3_270049_leistungsaufnahme_wp_ehz:
  state_class: "measurement"   
  unit_of_measurement: "kW"

I have all customization in an separated customize.yaml file. You have integrate it into the configuration.yaml with the !include command.

If i check mein config...yaml files in developper tool i get an error:
Konfigurationswarnungen Integration error: customize - Integration 'customize' not found.

here is my configuration.ymal section:
... scene: !include scenes.yaml customize: !include customize.yaml ....

and mein customize.yaml with propper format of 2 blanlks in front of state.. and unit...:
# Sensoren der Wärmepumpe für Statistik-Anzeigen aktivieren (für ISM7MQTT Integration) sensor.wolf_cha_0x3_270049_leistungsaufnahme_wp_ehz: state_class: "measurement" unit_of_measurement: "kW"

The customize.yaml file ist in /homeassistant/ just near the configurtion.yaml
Any ideas ?

[drose28357]

I found the solution. The configuration.yaml should contain this:
homeassistant:
customize: !include customize.yaml

I checked with devellopers / entities and now i have

friendly_name: Wolf CHA Leistungsaufnahme (WP + EHZ)
unit_of_measurement: kW
state_class: measurement

Thank you for this, helps a lot.
Anyone already implemented a statistic counter to show energy consumption on the energy dashboard?

My PR was merged in March 2025. So this topic can be closed. :-)

Thanks !
