WTH: Allow GJ (Gigajoule) as a long term statistic

As the author of 2 city heater meter custom components, I don’t understand why GJ (Gigajoule) is not allowed as a long-term statistic and I would like it to be added. This would allow tracking of long-term energy usage.

Even better, but I understand this is a lot more to ask, would be that the energy dashboard would get support for such meters instead (or maybe next to) how gas is supported.

I’ve seen people using a template sensor to convert the GJ value to m3 to integrate city heating into the energy dashboard. But in my opinion, this isn’t the right way :nerd_face: (see for example Integration in Energy dashboard · Issue #21 · golles/ha-kamstrup_403 · GitHub for examples)

The custom components:

Thanks!

I’m all ears for this idea!

I totally agree with this. Should be an easy fix to add GJ to the energy dashboard long-term statistics.

It is being added in Add GJ as supported unit for energy sensors by emontnemery · Pull Request #80870 · home-assistant/core · GitHub

Great suggestion. This will also allow Landis+Gyr Heat Meter - Home Assistant to show GJ usage on the energy dashboard.
