plmpower - control Insteon/X10 devices via SmartLabs PLM 2412S
is a helper program for
which enables communication with Insteon/X10 devices via SmartLabs
Power Line Modem, model 2412S.
It is run interactively by the powerman daemon.
It can also be useful as a standalone tool for debugging X10/Insteon
networks based on the above device.
Note the addresses of your Insteon/X10 devices.
Plug the PLM into an AC outlet, preferably on the same electrical phase
as the devices under control. Devices are available to bridge phases
if this is not possible.
Attach the PLM's serial port to your computer,
and ensure that nothing else is using the serial port such as the system
console or getty(8). Run
and try the interactive commands below to see if the devices respond reliably.
Once everything is working, configure
as a coprocess as described in powerman.conf(5).
-d, --device serial-port
Specify the path to the special file connected to the PLM's serial port.
-t, --timeout msec
Set the Insteon timeout to the specified number of milliseconds (default 1000).
-x, --x10-attempts number
Set the number of times to run every X10 command (default 3).
X10 does not provide an ACK/NAK mechanism like Insteon so we cannot
be certain that any particular X10 command completed,
therefore X10 commands are issued multiple times to increase confidence.
The following commands are accepted at the plmpower> prompt.
Address arguments may be Insteon (e.g. 1A.2B.3C) or X10 (e.g. G12).
Display help on the available commands.
Get info about the PLM.
Reset the PLM (clears the all-link db).
Turn on device.
Turn off device.
Query status of device (Insteon only).
Time round trip request/response to device (Insteon only).
