plmpower - control Insteon/X10 devices via SmartLabs PLM 2412S
plmpower --device serial-port
is a helper program for powerman
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
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
Once everything is working, configure powermand
to run plmpower
a coprocess as described in powerman.conf(5).
- -d, --device serial-port
- Specify the path to the special file connected to the PLM's
- -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).
- on addr
- Turn on device.
- off addr
- Turn off device.
- status addr
- Query status of device (Insteon only).
- ping addr
- Time round trip request/response to device (Insteon only).
