A bunch of new electricity retailers in AUS are going to spot rate billing. Being able to import spot rates into the data feed with consumption would give excellent stats on actual results and costs.
I would think you use your standard tariff config, unless you populate a tariff on the API, which overrides any tariff config you have for the system.
effectively using some of the extended data to override the default tariff.
I am going to play with the API in the meantime and get the tariff loaded so the PVO team can see what the data looks like, then its “just” logic.
