Bonjour

Je suis nouveau ici mais j' ai déja beaucoup lu et maintenant des question.
J' essay d' installer sur en Raspi pour visualiser zehner 350.

- new raspian jessie avec toutes les updates
- fair comme page #53 installer RaspiVMC

maintenant, comme est l' adresse pour accesser la visualisation, avec l'adress IP je vois apache fonctionne... excuser mois, mais j' ai pas encore beaucopt d' experiance acec apache et companie..

merci d' avence..

Bonjour, si tu veux on peut aussi le faire en anglais ...

1) Check is server.py is running, the command ps -ef | grep server
should return a line like this

root 14582 1 93 jui13 ? 19-20:00:06 /usr/bin/python /home/pi/bin/VMCserver.py

2) you can check communication with the 350 running one of the client scipt, like client1.py on a shell

3) to connect apache with a browser the URL should be http://IP_address_of_raspberry/VMC1.html

Or any other html page that should have been copied in the apache document directory (/var/www), to get the reading from the 350 on a web page, just call the cgi script using the URL:
http://IP_address_of_raspberry/cgi-bin/VMCbinjson.cgi

This script is called by the VMC.html page in order to get the current status of the 350, if you don't get an aynswer calling it directly, you won't get the VMC.html page displayed properly.

Hi there

Thanks for the replay.
I checked this, but so far I don't have the CA350 connected...

pi@raspberrypi:~ $ ps -ef | grep server
pi 16471 16460 0 11:06 pts/0 00:00:00 grep --color=auto server
pi@raspberrypi:~ $ sudo ps -ef | grep server
pi 16473 16460 0 11:06 pts/0 00:00:00 grep --color=auto server

so, the server doesent work, the WebAccess also not..

To manually start the server simply type ./VMCserver.py & in raspVMC directory.

This relies on /etc/VMC/VMC.ini being present and well configured.

Once the server is running you can proceed running a client and see if you get a message back from the 350.

Have you run the installation script ?

If you need to copy things in /var/www you need to do so using the sudo command

sudo cp *.html /var/www/

I will see if I can come up with a Jessie installation script as it is now the standard distribution for debian on the Pi.

Looks like the 350 is not responding to the request.

I suppose you configured the VMC.ini according to your hardware (USB converter or ttYAMA0 via the GPIO board).

When this problem was reported in the past, it was due to incorrect wiring of the connection to the 350.

1) To test the outgoing message from the Server, disconnect the 350, and connect pin 2 and 3 of the RS232/USB converter, run a client, you should then see the request being echoed back, this proves that the software is properly configured and running.

2) reconnect the 350 and exchange pin 2 and 3 connection to the 350, try the client again, see if you get an answer.

3) other possible problems:

- the USB/232 converter does not use RS232 level (some use TTL level which are not compatible with RS232 as used by the 350).
- Bad ground connection (which usualy end up with garbage being read by the converter, but this does not seems to be your case).
- if using the GPIO, the default ttyAMA0 console connection needs to be disabled by removing console=ttyAMA0 statement in the /boot/cmdline.txt

Hi

OK, will test different RS232/TTL converters. Which Pins should be connected for TTL/RS232 converter?

is there a schematic?

thx neo

Should be something like this

RJ45 350 --------------------------------RS232 converter dB9

Pin 2 RS232 RX Comfo Air -----------------pin 3 TX Data DTE
Pin 3 RS232 TX Comfo Air ---------------- pin 2 RX data DTE
Pin 8 GND --------------------------------pin 5 GND DTE

OK thx so far, now i have got a TTL to RS232 Converter, not USB.

My Setup:

350 (RJ45) - > RS232 -> Converter RS232-TTL -> Pin?? GPIO RaspiPi

Pin 2 RS232 RX Comfo Air -----------------pin 3 TX Data DTE -------- GPIO- RaspiPin??
Pin 3 RS232 TX Comfo Air ---------------- pin 2 RX data DTE GPIO --------- RaspiPin??
Pin 8 GND --------------------------------pin 5 GND DTE ---------- GPIO- RaspiPin??

Which Pins on Raspi?

THX

jcoenen · 22 Août 2016

Sorry fo the delay (got to enjoy the good weather while it last)

The GPIO pinout is here

Connect the converter power suppl on 5 volts and ground (5 V top left two pins - GND third pin)

connect the converter to the UART GPIO 14 TXD (output from the raspberry)
GPIO 15 RXD (input to the raspberry)

Don't forget to edit the cmdline.txt in the /boot directory of the raspberry to disable the system console lockup of the GPIO UAR, removing console=ttyAMA0,115200

Thanks, but I think in that case the javascript needs to be updated in the HTML pages in order to extract the values from the json and display them.

I suppose a better version would be to have a json with anonymous indexes and then link them with a language context that would be defined in a file. With one file for each language and define the langage in the VMC.ini file

That would be a nice to have in the 3rd version

marecki_0luk1 · 1 Octobre 2016

I have a question regarding setting speed. Every time I call http://IP/cgi-bin/VMCsetspeed.cgi?speed=X it changes speed but never get response. If I am using VMC1-3.html it works ok, but I need to call change speed only and get response f. ex. {Status: Done}.

jcoenen · 1 Octobre 2016

Indeed, the VMC does not send a reply when sending the command change speed (merely an acknowledgement of the command received), so the HTML page has to send a sense speed command after a few seconds in order to detect that the speed has indeed changed.

That means that if you use the change speed cgi in direct, you won't get anything back.

This could be overcome by writing a new change speed cgi script that does something like

- send the change speed command
- wait a few second to give the VMC the chance to update the speed
- read the speed
- send the response back to the caller.

Hi all,

I have a zehnder comfoair q450. I do find a red/back/yellow/white-port and a RJ45 at the top front (behind some plastic that you can slide away where the power cable is running under).

How can I use these ports to interface with a rpi? I can't seem to find the rs232 port at the back as in the examples in this thread.

Hoy Michaël,

I had a quick look at your model, it comes from the new generation of units.
I have also seen from Zendher a new remote controller for the new units (250 € ???), but from their connection diagram it looks like they have switched to a CAN bus ...which is not at all compatible with what was developed here (RS232 serial bus).

There are CAN bus interfaces for the raspberry pi, but not having the protocol, it would require some time and one unit to reverse engineer it.

JP.

Oups j'ai raté le message signalant le problème, c'est effectivement un problème de DNS (voir /etc/resolv.conf qui donne le nom du serveur de DNS et du domainname).

Mais mettre le nom dans /etc/hosts fonctionne aussi.

Je me permets une incursion dans ce fil car j'aimerais domotiser ma VMC Storkair aussi (3 vitesses, commandée actuellement par un bouton rotatif Niko) avec un module Z-wave et je me perds un peu dans la lecture des 61 pages de discussion.

Cela vous paraît-il possible et si oui, comment ?

jcoenen · 31 Octobre 2016

bonjour, ce système est écrit pour les unités storckair/Zehnder d350, d550 ...

Si votre Vmc est de ce type alors c'est possible.

Les nouvelles unité semblent être équippées d'un nouveau BUS (CAN) et donc vraissemblablement d'une nouvelle unités de commande, donc incompatible avec raspiVMC (pour l'instant).

De quelle unité disposez vous ???

Et oui le fil est très long ... (surtout quand il y du debug
