CHAPTER 5

daemons

The cbus.daemon package deﬁnes a number of daemons used to interact with the C-Bus network.

5.1 cdbusd

cdbusd is a daemon that is used to allow multiple applications on the same computer to share use of a PC Interface.

The daemon also provides clock services to the C-Bus network.

It is recommended when building C-Bus applications that you use the D-Bus interface to the network.

For more information on the D-Bus client interface, please see D-Bus Client API.

5.2 dbuspcid

dbuspcid is a daemon that emulates a PC Interface, allowing you to use it to connect to cdbusd.

This allows you to use applications on other computers to communicate with a virtual PCI, which in turn passes events

to cdbusd. It also allows you to use applications that do not support the cdbusd API directly.

5.3 sage

sage is a web interface for lighting controls, similar to Wiser, except it doesn’t suck:

• It has no dependancy on Flash player or a device-speciﬁc app (it uses WebSockets instead).

• It has a very minimalist, touch-friendly UI based on jQuery Mobile. This UI is also used on desktop.

• It works as a “web app” on iOS 4.2 and later (due to patchy WebSockets support).

• It has no requirement for a ethernet-based PCI (serial/USB are ﬁne).

• It doesn’t have hard coded backdoors and changing the password actually locks previous users out. (However

some browsers don’t implement support for HTTP Authentication requests on WebSockets)

It connects to cdbusd as it’s abstraction layer, and only presents lighting events to clients.

It is made of some parts:
