Added manual cooling and VWZ binding

[kolibrie-eric]

Added manual cooling option as offered by the 700 when you have a heat pump installed. Added VWZ (heatpump controller) items to the hmu configuration file. Need help with translation though

[kjoglum]

@kolibrie-eric I am testing your modified config files for my Vaillant heating setup: VWL 85/2, VRC 700, VWZ.

Although, I do not get any reasonable values for LiveMonitor. I am interested in getting the "Current Power Consumption", so I have been trying:

pi@raspberrypi:~$ ebusctl write -c hmu ReadLiveMonitor 003224
done

pi@raspberrypi:~$ ebusctl read -v LiveMonitor
hmu LiveMonitor subid=24;value=0c 00

Edit: Realise it would be the HEX value I am receiving.

[kolibrie-eric]

@kjoglum,

The command is okay. It gets you the current power consumption when you read the LiveMonitor value as you did. The actual value 0c00 is a UIN (see Ebus specification) and needs interpretation. Here is a piece of Javascript code to help you decode its value (UIN):

function UIN(lbyte,hbyte)
{
    return parseInt(hbyte+lbyte,16) / 10
}

The answer is 1.2kW.

Here is list of all the values and their interpretation:

Desired supply temperature (1f) : D2C Supply temperature (20): D2C Power consumption (24): UIN / 10 Power generated (23): UIN / 10 Modulation (25) : D1B Air intake temp (26): D2C

Thanks for sharing!

Do you also have some sort of automatic repeat sequence to trigger LiveMonitor, e.g. MQTT? I am successfully able to trigger LiveMonitor manually from ebusd using mosquitto_pub -m '003224' -t 'ebusd/hmu/ReadLiveMonitor/set', but uncertain how to repeat automatically (similar to -m '?1' as used for poll priority for /get values).

[kolibrie-eric]

@kjoglum

I created the repeat sequence in node red where you can poll the values and receive updates through the MQTT interface. Basically, you send the ebusctl message to the TCP/IP port 8888, localhost.

Good luck!

@kolibrie-eric

Managed to do the same with a scripted Time cron rule using the MQTT binding / actions for OpenHab. Works perfectly, thanks!

Hi, when can we expect to see this branch merged? Amazing feature, the ability to get VWZ live monitor settings. @kolibrie-eric which payload shall we use for ReadLiveMonitorMain?

[john30]

can you post your scan result please? I'd like to make sure that this does not influence different versions of the 700

[stefanheijnen]

How is this PR progressing? Also I see some errors in your https://github.com/kolibrie-eric/ebusd-configuration/blob/master/ebusd-2.1.x/en/vaillant/08.hmu.csv file @kolibrie-eric

Line 3, 19, 36 etc. Looks like an error with merging or so?

I'm very interested in the data from the live monitor. I install and service heatpumps every day. Put programming is not in my skill set unfortunately.

[karusell]

Could you please provide these local files for 76.vwzio and e8.fmu ? I would like to get also the 76.vzwio data.

Thank you.

[lfrlucas]

@karusell I also need those ones. I solved by creating 76.vwzio and e8.fmu from existing 08.hmu.csv. It seems to work for some fields.

[karusell]

If we can find out the config for VWZIO it is for both technical components "Vaillant VWZ AI" and "Vaillant VWZ MEH 97/6" because they are identically construced control units.

@lfrlucas could you provide me your files? thank you!

[lfrlucas]

my files are a simple copy of 08.hmu.csv
