Method Details

write

public void write(String edgeId,
 TimestampedDataNotification data)

Description copied from interface: BackendTimedata

Sends the data points to the Timedata service.

Specified by:

write in interface BackendTimedata

Parameters:

edgeId - The unique Edge-ID

data - Table of timestamp (epoch in milliseconds), Channel-Address and the Channel value as JsonElement. Sorted by timestamp.

write

public void write(String edgeId,
 AggregatedDataNotification data)

Description copied from interface: BackendTimedata

Sends the data points to the Timedata service.

Specified by:

write in interface BackendTimedata

Parameters:

edgeId - The unique Edge-ID

data - Table of timestamp (epoch in milliseconds), Channel-Address and the Channel value as AggregatedData. Sorted by timestamp.

write

public void write(String edgeId,
 ResendDataNotification data)

Description copied from interface: BackendTimedata

Sends the data points to the Timedata service.

Specified by:

write in interface BackendTimedata

Parameters:

edgeId - The unique Edge-ID

data - Table of timestamp (epoch in milliseconds), Channel-Address and the Channel value as ResendData. Sorted by timestamp.

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

Returns:

the query result; possibly null

Throws:

OpenemsError.OpenemsNamedException

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

id

public String id()

Description copied from interface: Timedata

Returns a unique ID for this OpenEMS component.

Specified by:

id in interface Timedata

Returns:

the unique ID
