DALI

The DALI component provides methods to scan and ping control gears. It uses DALI as RPC namespace and provides the methods:

• DALI.GetConfig to obtain the component's configuration
• DALI.SetConfig to update the component's configuration
• DALI.GetStatus to obtain the component's status
• DALI.StartScan to start scanning for control gears
• DALI.PingKnownDevices to ping scanned control gears

All control gears are controlled through light:0 component.

Methods:

DALI.SetConfig

DALI component does not provide configuration

DALI.GetConfig

DALI component does not provide configuration

DALI.GetStatus

DALI.GetStatus does not expect any arguments

DALI.StartScan

This method starts scanning the DALI bus for control gears.

DALI.StartScan does not expect any arguments

Response

The result from this method is null when scan is started succesfully.

If invoked while scanning is already in progress, an error is returned:

{
  "code": -114,
  "message": "scan is already in progress"
}

If invoked and internal dali bus driver can not be loaded, an error is returned:

{
  "code": -114,
  "message": "driver error"
}

DALI.PingKnownDevices

This method pings all scanned control gears. If some control gears can not be accessed, error control_gear_missing is raised in component status.

DALI.PingKnownDevices does not expect any arguments

Response

The result from this method is null when pinging is started succesfully.

If invoked while scanning is already in progress, an error is returned:

{
  "code": -114,
  "message": "scan is already in progress"
}

If invoked and internal dali bus driver can not be loaded, an error is returned:

{
  "code": -114,
  "message": "driver error"
}

If invoked and bus has hever been scanned, an error is returned:

{
  "code": -114,
  "message": "bus not scanned"
}

If invoked and there are no control gears found during scan, an error is returned:

{
  "code": -114,
  "message": "there is no devices on bus"
}

Configuration

DALI component does not provide configuration

Status

The status of the DALI component contains information about number of scanned control gears on DALI bus and scanning process information.

Properties:

Property	Type	Description
cg_count	number or null	Number of scanned control gears (null if scan has never been executed)
scan	object	Information about the scan process, only present when scan is running Property Type Description cg_count number Number of found control gears during scan started_at number Unix timestamp, start time of the scan process (in UTC)
errors	array of type string	Shown only if at least one error is present. May contain control_gear_missing, driver

info

* control_gear_missing is an error indicating that some ot the scanned control gears can not be accessed.

* driver is an error indicating internal DALI driver error.
