Plugwise and Linux

Post by **Floppe** » Fri Mar 27, 2009 5:20 pm

Do you know if the source stick still uses FTDI chip? My linux box does not find anything when I plug in the stick, other serial converters does work. lsusb does not list anything either.

EDIT: it works in my MythTV Frontend so to answer my question, yes it still uses FTDI.

Hello Maarten.

I'm really interested in the source for how to read power used since last reading. I'm planning to build charts using rrdtool (probably cacti) and using current wattage for that is inaccurate when polling the devices in 5 min intervals.

Thanks for your fine work

@Foppe: I'll try to put something online for you this evening...

Foppe, can you fill in your e-mail address so I can e-mail you the sources?

Maarten, I have now enabled emailing. Really excited about the sources

Maarten,

the downloadlinks on your webpage for the python scripts are broken, can you fix them?

Download links fixed! Sorry for the inconvenience... And thanks for reporting.

Maarten,

while awaiting the arrival of my Plugwise modules I tried to convert your python script to perl. I almost got it working, except for the calculation of the CRC-16 value.

After commenting out (in your script) the lines initializing the serial port and the lines writing/reading to/from it, I run your script as follows:

Code: Select all

python pol.py -p /dev/ttyUSB0 -o 000A1100003111AB

This should give me a CRC value of AC92, but when adding a print-statement at the end of the CRC calculating routine, I get this as a CRC value: 38F7

The complete string looks like this: 0017000A1100003111AB0138F7

Can you confirm that AC92 is really the correct CRC value, or is indeed 38F7 the correct value.

As soon as my plugs arrive I will try to sort it out myself, but I wanted my code to be finished before they arrive.

38F7 is indeed the correct value. I just checked it. Good luck with the rest of your perl script.

CRC calculations are working.

Turned out that the ccittcrc routine from the Perl module Digest::CRC defaults to an init value of 0xffff when doing calculations, instead of 0.

From the string that Maarten supplied:

0024 000D6F00002366BB00003681 000457C8 01 85 0000 0473 0007 48B4253801F74D

I can add the following:

The part of the string in bold/italic is the hardware revision of the plug. The code above is typical for the Circle+. The normal plugs I have, have HW revision 0000 0440 0107.

The string I get back from my Circle+ looks almost the same as from Maarten's Circle+ :

0024 000D6F000037B4A7 0000422C 00044040 01 85 0000 0473 0007 48B4253801 CAB4

The parts of the string that are in bold or in italic more or less have a known meaning. Still looking for the rest.

I'd also like a copy of that if it's possible.

Hi all,

I'm thinking about developing an application which from time to time scans all the devices (detects them dynamically) on the Plugwise ZigBee network and reports specific info about each one to a file (which would then be read by other applications). One thing that is missing is the command or set of commands to do this device discovery. Anyone? The alternative is to store all the device ids and poll each one and get timeouts for the devices that are out of range or disconnected for some reason.

Thanks in advance

Hi Maarten,

Somebody tuned up the private-msg-minimal-post-thingy up from 30 to 50 ... so have to go public with this one.

I've got myself a plugwise stick and circle+ today. Got it working on windows and was looking for your linux version. However there seems to be a mysql problem on your server.

Hi all,

Does anyone know how to get 5min average readings from the plugs? I started to develop my own service which shall log all plugs to a MySQL database which Cacti (or other monitoring application) in turn shall read the data and graph it. However, I did not think this through as the log buffers only shows past hours, not the current hour.

Or maybe it's only possible to get 1hour average readings like the source software does.
