Steps
Publish a TariffProfile with associated RateComponent and ConsumptionTariffInterval resources describing price bands
Have client end devices discover pricing resources through their FunctionSetAssignmentsList
Poll or subscribe to the current active TimeTariffInterval to obtain the in-effect price
Keep clients synchronized via the IEEE 2030.5 Time function set so price validity windows are evaluated against the correct clock
Use published price signals as an input to separate DER/DRLC program logic that decides local device response
Known gotchas
The pricing function set only distributes price information — it does not itself dispatch DER behavior, so linking price signals to actual battery or inverter response requires separate DER program logic on the client
Without properly synchronized time via the Time function set, clients can misapply a price interval to the wrong time window
