getLatestValue

CompletableFuture<Optional<Object>> getLatestValue(ChannelAddress channelAddress)

Gets the latest known value for the given ChannelAddress.

Parameters:

channelAddress - the ChannelAddress to be queried

Returns:

the latest known value or Empty

getResendTimeranges

Timeranges getResendTimeranges(ChannelAddress notSendChannel,
 long lastResendTimestamp)
                        throws OpenemsError.OpenemsNamedException

Gets the Timeranges to data which got not send. The not send data gets determined with the notSendChannel and the lastResendTimestamp.

Parameters:

notSendChannel - the channel with the timestamps where the data got not send

lastResendTimestamp - the timestamp of the last resend; negativ if there is no lastResendTimestamp

Returns:

the Timeranges

Throws:

OpenemsError.OpenemsNamedException - on error

 ZonedDateTime toDate,
 Set<ChannelAddress> channels)
                                                                               throws OpenemsError.OpenemsNamedException

Queries data to resend.

Parameters:

fromDate - the start date

toDate - the end date

channels - the channels to resend

Returns:

the query result; possibly null
