deactivate

protected void deactivate()

Description copied from class: AbstractOpenemsComponent

Handles @Deactivate of implementations. Prints log output.

Overrides:

deactivate in class AbstractOpenemsComponent

getResendTimeranges

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

Description copied from interface: Timedata

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

Specified by:

getResendTimeranges in interface Timedata

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

queryResendData

public SortedMap<Long,SortedMap<ChannelAddress,com.google.gson.JsonElement>> queryResendData(ZonedDateTime fromDate,
 ZonedDateTime toDate,
 Set<ChannelAddress> channels)
                                                                                      throws OpenemsError.OpenemsNamedException

Description copied from interface: Timedata

Queries data to resend.

Specified by:

queryResendData in interface Timedata

Parameters:

fromDate - the start date

toDate - the end date

channels - the channels to resend

Returns:

the query result; possibly null

Throws:

OpenemsError.OpenemsNamedException - on error

queryHistoricData

public SortedMap<ZonedDateTime,SortedMap<ChannelAddress,com.google.gson.JsonElement>> queryHistoricData(String edgeId,
 ZonedDateTime fromDate,
 ZonedDateTime toDate,
 Set<ChannelAddress> channels,
 Resolution resolution)
                                                                                                 throws OpenemsError.OpenemsNamedException

Description copied from interface: CommonTimedataService

Queries historic data.

Specified by:

queryHistoricData 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

Returns:

the query result; possibly null

Throws:

OpenemsError.OpenemsNamedException

queryHistoricEnergy

public SortedMap<ChannelAddress,com.google.gson.JsonElement> queryHistoricEnergy(String edgeId,
 ZonedDateTime fromDate,
 ZonedDateTime toDate,
 Set<ChannelAddress> channels)
                                                                          throws OpenemsError.OpenemsNamedException

Description copied from interface: CommonTimedataService

Queries historic energy.

Specified by:

queryHistoricEnergy in interface CommonTimedataService

Parameters:

edgeId - the Edge-ID; or null query all

fromDate - the From-Date

toDate - the To-Date

channels - the Channels

queryHistoricEnergyPerPeriod

public SortedMap<ZonedDateTime,SortedMap<ChannelAddress,com.google.gson.JsonElement>> queryHistoricEnergyPerPeriod(String edgeId,
 ZonedDateTime fromDate,
 ZonedDateTime toDate,
 Set<ChannelAddress> channels,
 Resolution resolution)
                                                                                                            throws OpenemsError.OpenemsNamedException

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 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

Returns:

the query result; possibly null

Throws:

OpenemsError.OpenemsNamedException
