Sensor for Vallox DigitSE RS485 ventilation system with integration into FHEM.

[m26872]

@Heinz What Fhem plot style and font are you using?

[Heinz]

@m26872
I modified the dark style. If you need the files I will upload em with a description how to integrate those.

[m26872]

@Heinz Yes please! I really liked those plots.

I wouldn't mind it in german (as usual with Fhem stuff), but it's a lot easier for me with english.

[Heinz]

@m26872
I simply copied the dark style of FHEM and named it dark2:

copy the following files to your FHEM subfolder www/pgm2
dark2style.css
dark2svg_defs.svg
dark2svg_style.css

In your FHEM.cfg select this style for your WEB Frontend e.g.:
define WEB FHEMWEB 8083 global
attr WEB stylesheetPrefix dark2

That's it.

If you want to have other plot colours edit the files starting with dark2svg... I think it is self explaining.

[Heinz]

For those who want to have the FHEM files here they are:
_MYSENSOR_Vallox.cfg
simply place the file in FHEM's subfolder FHEM and include it your fhem.cfg:

include ./FHEM/_MYSENSOR_Vallox.cfg

And here are the plot files which have to be placed in the subfolder www\gplot
SVG_FileLog_Vallox_6.gplot
SVG_FileLog_Vallox_5.gplot
SVG_FileLog_Vallox_4.gplot
SVG_FileLog_Vallox_3.gplot
SVG_FileLog_Vallox_2.gplot
SVG_FileLog_Vallox_1.gplot

You will likely have to adapt the room and group names, and of course the german names, sorry for that.

@Heinz
Nice! Now I really want to buy a Vallox ... (and a house...)

[Skjall]

Moin @Heinz,
is it possible to use a RS485 USB-Stick (http://shop.in-circuit.de/product_info.php?cPath=38&products_id=81) instead of this construction? I've tried it with your .net Sniffer on my Windows PC and it worked well.

Thanks
Skjall

[Heinz]

You can use this rs485 to usb adapter to control the vallox device, no problem there. But do you intend to use your windows pc as controller then? Or do you want to use the stick directly with fhem? this would require some software which takes the serial telegrams and imports the values into fhem... or any other homeautomation controller.

[Skjall]

No, the Windows PC was only for testing and verifying that the RS485 Connection workes well.

My preferred solution would be this stick at the Raspberry Pi which is running the FHEM. Therefor I'd need a module to read the stream and interpret it in the FHEM format. Problem: I've never written a module. It would be possible somehow.. in some month. ;)

The alternate solution would be your mysensor system. Especially because its running and tested. Problem: The Hardware. I have no experience in arduino and absolutly no idea how to build such a board. Thats why I thought I could plug the stick to an arduino and make it magicly work. ;)

EDIT: Ok. It is easier than I thought to write this module. I'm working on it and the main functions should be finished this week. I'll publish it, if it is ready for testing.

[Heinz]

Ah ok I see. Probably you can get some help in the fhem forum. I also thought about doing this using a raspi... you could use the library to write a standalone exe which reads the serial stuff from usb and sets the values in fhem using the webinterface.

[boehrian]

Hello, Thank you for this Tool. I have rebuild it but I get no Data in Fhem and the serial Monitor from Arduino. Can every one help me?

This is the output from serial Monitor.

I get no reply from the Vallox.
Is your original Vallox controller online

[Heinz]

The "no reply" message is from the mysensors library, but I don't know what it means.
The line "started cyclic update timer" indicates that the sensor initialized successfully, but it is missing in your output.

My latest code is online at
https://github.com/windkh/valloxserial/blob/master/examples/mysensors/ValloxSensor.ino

[hek]

Use the log parser to help you interpret the log.

[ausbremen]

@heinz
Hi Heinz, the SVG_FileLog_Vallox_#.gplot files are empty ...probably the link is dead...could you reup them? Or could you send them tio me?

Thanks, Holger

[ausbremen]

@heinz
Sorry...everything is fine with the gplot files...it was my fault trying to look at them with the crimpson editor...instead of FHEM gplot

[captaindork]

Hello Heinz, all,
first of all thank you for sharing your work in this thread!
I have not to much skills around programming and arduino, but was however able to build this and integrate my Vallox 90 SE into ioBroker. Absolutely Great!
You mentioned the bypass damper above and I see you have visualized it in fhem. I found the Value to set the Threshold temp for this (31), however I wonder where you got the actual bypass position from. Which Value shows if its open or closed?
I do not want to control it, i just would like to log the Position Status to see when it happens.

Thanks a lot i feel blind :)

[Heinz]

Hi @captaindork
sorry for delay,.... the position of the damper (which is the bypass) is indicated through a single bit of the multi purpose IO-Port 2. The library defines that as property 38 DamperMotorPositionProperty.
In the mysensors example it is published as
const uint8_t DAMPER_MOTOR_POSITION = 42;
The value is either 1 or 0.

I mapped it in FHEM as follows

attr MYSENSOR_Vallox mapReading_DamperMotorPosition 42 value1

define MYSENSOR_Vallox_DamperMotorPosition dummy
attr MYSENSOR_Vallox_DamperMotorPosition alias WRG-Bypass
attr MYSENSOR_Vallox_DamperMotorPosition devStateIcon 1:rc_GREEN 0:rc_BLANK
attr MYSENSOR_Vallox_DamperMotorPosition event-on-update-reading state
attr MYSENSOR_Vallox_DamperMotorPosition group Status
attr MYSENSOR_Vallox_DamperMotorPosition icon vent_bypass
attr MYSENSOR_Vallox_DamperMotorPosition room Lüftung
attr MYSENSOR_Vallox_DamperMotorPosition sortby 3
define MYSENSOR_Vallox_DamperMotorPosition_Notify notify MYSENSOR_Vallox:DamperMotorPosition:.* { my $d = sprintf ("%.0f", ReadingsVal("MYSENSOR_Vallox","DamperMotorPosition", 0));; fhem("set MYSENSOR_Vallox_DamperMotorPosition $d");;}
define MYSENSOR_Vallox_DamperMotorPosition_Notify2 at +*00:01:00 { my $d = sprintf "%.0f", ReadingsVal("MYSENSOR_Vallox","DamperMotorPosition", 0);; fhem("set MYSENSOR_Vallox_DamperMotorPosition $d");;}

[RHead]

Hi.

Can you make exact parts list for this setup.
