        Description copied from interface: CommonTimedataService
        Queries historic energy per period.

        This is for use-cases where you want to get the energy for each period (with length 'resolution') per Channel, e.g. to visualize energy in a histogram chart. For each period the energy is calculated by subtracting first value of the period from the last value of the period.

        Specified by:
        queryHistoricEnergyPerPeriod in interface CommonTimedataService
        Parameters:
        edgeId - the Edge-ID; or null query all
        fromDate - the From-Date
        toDate - the To-Date
        channels - the Channels
        resolution - the Resolution in seconds
        Throws:
        OpenemsError.OpenemsNamedException
      • getLatestValue

        public java.util.concurrent.CompletableFuture<java.util.Optional<java.lang.Object>> getLatestValue​(ChannelAddress channelAddress)
        Description copied from interface: Timedata
        Gets the latest known value for the given ChannelAddress.
        Specified by:
        getLatestValue in interface Timedata
        Parameters:
        channelAddress - the ChannelAddress to be queried
        Returns:
        the latest known value or Empty
