Getting Daily comsumption via the API from the VRM, ESS Charge SOC limit via HA

I'm looking to get the daily consumption figures as listed in the bottom of the VRM page via the API, does anyone know the exact singe to pull this on a date?

I'm also looking to alter the ESS battery charge SOC value either via Home assistant or via Node-Red (using solcast as a value on how much I charge the batteries), If I use home assistane I already read the solacast values so will be using these to gauge what I set it to. I could also use Node-red on my Cerbo, but if I do that how do I get my Solacast values into that?

I can't see a value in the ModBus excel file for ESS battery charge timings or SOC value.

Kind regards

Hi @Si Mon I'm not familiar with VRM api so can't help there.

But you're other suggestion of getting the solcast data you could just do what homeassistant is doing (querying the solcast api to get the data) but in node red. Or you could query homeassistant which has already queried solcast from node red.

Both have api's (you'd use the http node in node red to get the values). I'd personally load the data into global_variables from the http node.

That way you can do the ESS check's in another flow and have access to the data.
