JMRI: Powerline System Names

Individual inputs (Sensors) and outputs (Turnouts and Lights) in JMRI are accessed via names. For information on the general scheme, please see the naming page in the technical documentation.

X10

X10 devices are addressed via a "House Code" of A through P, and a "Device Code" of 1 through 16.

JMRI configures the adapter to use House Code "A" now. We'll eventually make that configuable, but for now that means that input messages will only be received from devices set to house code A.

Outputs (Lights and Turnouts) in house code A are numbered with their device code, e.g. PT1 is device 1, PT2 is device 2, etc.

Depending on your setup, you might be able to access other housecodes by adding "16"s to the number, e.g. PT17 is device 1 in housecode B, etc.

Eventually, it will be possible to use a letter-number combination to address X10 devices. For example:

This code has not yet been written, though.

Insteon

Insteon adapters are labelled with a four-part number that looks like 01.2A.B4.CD, four bytes in hexadecimal. These are just random strings as part as the user and the program is concerned, and we don't make any effort to subdivide them. We will accept dropping of leading zeros (e.g. 01 and 1 can be used in a group, so both 1.2.3.4 and 01.02.03.4 are accepted). We also accept either lower case or upper case letters. Extra zeros, e.g. numbers beyond two digits, are not accepted. Note that .23. is a hexadecimal 23, decimal 19. Entry of addresses in decimal form it not (yet) available.

More Information

More information on the X10 hardware can be found on the (admittedly obnoxious) X10 web site.
