Setting up carbon intensity

[WyndStryke]

Hi,

I'm trying to set up the carbon intensity feature in the predbat planning, I think I'm most of the way there (the carbon_intensity_uk integration is picking up the carbon data today, and the forecast is being loaded into predbat), but it doesn't seem to be pulled into the actual plan as far as I can see.

If anybody spot what I'm missing, it'd be great :-)

This is predbat running in 'read only' mode, with charge&discharge control.

The data looks like this:

current_period_from: 2025-01-13T15:00:00+00:00
current_period_to: 2025-01-13T16:00:00+00:00
current_period_forecast: 271.5
current_period_index: very high
optimal_window_from: 2025-01-14T00:00:00+00:00
optimal_window_to: 2025-01-14T04:00:00+00:00
optimal_window_forecast: 145.625
optimal_window_index: moderate
optimal_window_48_from: 2025-01-14T23:00:00+00:00
optimal_window_48_to: 2025-01-15T03:00:00+00:00
optimal_window_48_forecast: 195.375
optimal_window_48_index: high
unit: gCO2/kWh

Could this difference in units be at all relevant (g/kWh vs gCO2/kWh)?

predbat.carbon_now
Grid carbon intensity now
0	friendly_name: Grid carbon intensity now
state_class: measurement
unit_of_measurement: g/kWh
icon: mdi:molecule-co2

vs

sensor.carbon_intensity_uk
... 
unit: gCO2/kWh

Looks very similar to this #1131 , but I've removed / reinstalled the jfparis integration from HACS, restarted HA a couple of times, and things still seem to be the same. That also seems to be the case in 1131, removing / restarting didn't fix it, but from the description it randomly fixed itself after a predbat update.

FYI to anyone interested, the problem was indentation in the apps.yaml. Obvious now that I've spent more time with home assistant, but wasn't so obvious when I was a newbie.

https://springfall2008.github.io/batpred/energy-rates/#uk-grid-carbon-intensity

says

Once it is active update apps.yaml to link Predbat to the Sensor (if it's not already in your template):

# Carbon Intensity data from National grid
carbon_intensity: 're:(sensor.carbon_intensity_uk)'

But what is not so obvious to newbies from that is that there is indentation required.

thanks for the info, the documentation usually (but not 100% always) has all yaml left aligned, but it is inconsistent

I will add something further to the apps.yaml intro about indentation https://springfall2008.github.io/batpred/apps-yaml/#warning-appsyaml-file-format and will ensure that all the sample YAML is indented correctly
