Sensor for Vallox DigitSE RS485 ventilation system with integration into FHEM.
-
My house contains an air ventilation system from the company vallox. The controller of this device is an old school wall mounted micky-mouse-button device with an ugly LCD display. Using this controller is really annoying and the user expirience is really too much "last-century".
The mission was to have the display data as well as the control buttons on my tablet. Another unflexible thing is the so-called boost-switch which can be pressed right before you have a shower. The switch makes the ventilation system run on max for 45minutes. if somebody accidentaly pressed the button in the midnight thinking it is a light-switch, the ventilation started roaring for 45minutes. I finally had to get up from bed walk downstairs and switch the system off to find some sleep again. This should also be a problem of the past. The idea was to handle the button using my new mysensors device. One click should start the ventilation for 45minutes, two clicks for 30minutes and a long click should stop the boost mode. I want to be able to interrupt the boost switch mode even from my iphone...I will post some pictures of the project the next days together with some details. I uploaded the library to control the vallox device via RS485 together with a mysensors sketch at: https://github.com/windkh/valloxserial.git
The sensor uses around 40 different child sensors as the vallox device offers so many different data.

@Heinz Holy cow 40? I bet that took a while..

This is the original controller of the ventilation system. It displays the fan speed as well as the 4 temperatures: incomming air, exhaust air, inside temp, outside temp. You can control the fan speed level 1-8 by pressing the up and down buttons.
The controller communicates with the main device via a RS485 bus. To read the data sent between both parties I used an arduino mega as it has more than one hardware serial lines. This leads to less corrupt telegrams when communicating via RS485. You need at least one RS485 to TTL converter. As I had two of em I used one for sending and one for receiving telegrams:
I had to develop a serial library that is able to interpret the vallox protocol. The protocol description can be found here:
http://knx-user-forum.de/gebaeudetechnik-ohne-knx-eib/18274-vallox-rs485-schnittstellenbeschreibung.htmlThe library is used by the vallox-sensor-sketch to retrieve the data from the RS485 bus. The variables are send to the mysensors controller as different sensor values (41 different variables!).
integration into FHEM was very easy. The following picture shows the most important variables and their readings. I did not import the other ones as I do not have any original CO2 Sensor nor humidty sensors attached.
I also added some buttons to FHEM to make controlling of the vallox device easier:
Inspired by samppa I added some calculations for efficiency of the heat exchanger see also
http://forum.mysensors.org/topic/38/measuring-efficiency-of-home-air-ventilation-heat-exchanger-unit/3The fan speed can be controlled by any tablet or phone in my house now. If somebody accidentally pushes the boost switch in the shower in the night it does not bother me any longer. I can easily turn it off using my iPhone

BTW finding an appropriate housing for your sensors is not very easy. Housings should be nice and fit into their environment. Therefore I put my gateway in a sporty metal adidas housing:
Later if found a sticker at the bottom of the box: "medium impact sports bra"!
Oups!

I'd be worried about shorting against the walls of the can, and shielding my RF signals... But if it works and you like it... well there you go!

there is an external antenna for the radio...

Ha!looked like a cable to me at first glance!!

After some months of testing a little update:
I received some e-mails questioning the so called "heat recovery cell bypass" mode. There is a damper inside the device that can
is switched automatically by the vallox-controller to bypass the heat recovery cell (HRC) to avoid heating up the house during the
summer months. Well, when you open the device on a hot summer day you will probably see the damper in an obvious wrong position:
the air does not bypass the HRC! Huh! whats wrong here?Explanation:
The device tries to cool down the incoming air by leading it through the HRC which is still colder than the temperature outside. If the temperature outside is colder than the air inside the house the damper is switched to the expected position. There are two things to you have to do to make all that work correctly:- turn off heating mode (the LED of the left most button on your control device must be off)
- the HRC bypass temperature must be set to a value below the outside temperature (e.g. 14 degrees)
To illustrate that effect I logged the temperatures in FHEM:
Sorry for the german labels.
The first plot shows the damper position: blue background: HRC bypass is active.
The second plot shows the temperature outside the house (blue) and the temperature inside the house (red)As soon as the temperature outside is greater than the temperature inside the HRC bypass is deactivated to cool the incoming air by leading the air through the "colder" HRC.
The fourth diagram shows the temperature of the air that is entering the rooms (purple) and the temperature outside the house (blue).
You can see that the fresh air entering the rooms is lower than the temperature outside: the cooling effect works (even if it is only few degrees)To all guys thinking about how to control the damper on their own logic from a raspi or arduino. This is not neccessary as the vallox logic works very well.
-
Some people asked if the library is able to control other parameters than the fan speed. The answer is yes. The following screenshot shows my sliders and buttons in FHEM:
Sorry for the german labels again:
The first group shows the power state (ON/OFF), the heating-state (winter season=ON, summer season=OFF) and the HRC damper position (inactive=OFF). See last post.The second group shows some alerts (none at the moment)
the third group shows a button to switch between summer and winter season. The sliders control some temperature thresholds and other parameters.If you want to have a look at the bus data yourself you can download my sniffer tool which is a .Net port of the serial library described above under valloxserial.net
-
@Heinz What Fhem plot style and font are you using?
-
@m26872
I modified the dark style. If you need the files I will upload em with a description how to integrate those.
-
@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.
-
@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.cssIn your FHEM.cfg select this style for your WEB Frontend e.g.:
define WEB FHEMWEB 8083 global
attr WEB stylesheetPrefix dark2That's it.
If you want to have other plot colours edit the files starting with dark2svg... I think it is self explaining.
-
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.cfgAnd 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.gplotYou 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...)
-
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
-
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.
-
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.
-
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.
-
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.

Is your original Vallox controller online
-
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
-
Use the log parser to help you interpret the log.

@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
-
@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
-
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
-
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 value1define 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");;}

Hi.
Can you make exact parts list for this setup.
-
Ok ... after my holidays.
-
Well basically the part list is very simple
1x Arduino Mega 2560
1x NRF24L01+
1x Pushbutton
2x MAX485 Module TTL Switch Module (one for sender, one for receiver)
(e.g. https://protosupplies.com/product/max485-ttl-to-rs-485-interface-module/)The 1x Resistor 120Ohms is only neccessary if not already mounted on the MAX485 Module. It depends on what module
you bought. So have a look at the layout and check if there is a 120Ohms resistor mounted between pins A and B.
The module (https://protosupplies.com/product/max485-ttl-to-rs-485-interface-module/) already contains that resistor.Optionally you can add a capacitor between + and - to stabilize the voltage level if your power supply is a weak one.
Anyone will do like 10uF, 100uF...
-
Note that you can make use of any MAX485 module that is suitable for the arduino (5V). Basically they are all the same except for a few minor tweaks like LEDs or other non relevant stuff.
-
I found this old thread and since I have a Vallox machine it's interesting. RS485 is new to me but MySensors isn't.
Can I have a node like this described by Heinz parallel with the "mickey mouse"-display? Using the display's connector? Or is it one or the other?
I'd feel better having both (manual display&buttons and connection to MySensors=>Domoticz, in my case).
