Is this the only error you are getting.
Comment that part out and try the rest.

All lines are giving the same error. How can I deduct what value is for what field? I have a Alpha Innotec WSZ heatpump.

I can't help you any further because i'm not a Python specialist.
Are you using Python 3.4.2?
It looks like the following part doesn't works correctly:

Code: Select all

stat = struct.unpack( '!i', s.recv(4))[0]
len = struct.unpack( '!i', s.recv(4))[0]
array_calculated = []
for i in range(len):
    array_calculated.append(struct.unpack( '!i', s.recv(4))[0])
I've got it working with trail and error.
At least you can get de data from the heatpump and that's the first step.

I checked the values by comparing them directly with the values shown on the display of the heatpump.

Yes python 3.4.2, anyone else? It seems that index of the array is invalid somehow.

I didn't see any replies since the last couple of months ;)

Anyway, I've got it working all the way. I didn't use the kWh anymore, since the values are not not electrical kWh's but heating, so there is a huge difference between these values and the actual electrical power consuming....
See the attachments for temperatures, which is working fine ;)

Hi,
I´m trying to get the switch working but it keeps logging I want only the changes in the log not every minute when the script runs.

this is my json
conn.request("HEAD","/json.htm?type=command&param=switchlight&idx=327&switchcmd=Set%20Level&level=" + (str(array_calculated[119])))

Hi, could you help to get this working in Domoticz? What should I do with this code? Snap er de ballen van..
In hardware you can add a dummy and than add virtual sensors. If you did this you can see the virtual sensor in devices.
Every virtual sensor gets an IDX copy this and place it where I put the star *
# Temp buiten
conn = httplib.HTTPConnection("192.168.200.15:8080")
conn.request("HEAD","/json.htm?type=command&param=udevice&idx=924&nvalue=0&svalue=" + (str(float(array_calculated[*])/10)))



To get output from the script you can create a cron job that is running every minute.

You can send me a pm if you want.

I also found this piece of software: https://github.com/coolchip/luxtronik2
In the code you find: 'Read all readable data'. So it might extract more data than the tool in this forum.

Which one is better do you think?

You placed the star at the wrong position. array_calculated[*] is the place in the array being read from the luxtronik. You should leave that. You should change the udevice&idx=924 to the right device in Domoticz. So 924 should be changed to whatever ID is being used in your own virtual sensor ;)

Hi,

Interesting ;)

My script (carefully stolen) only reads stuff. It actually reads everything from the Luxtronik, but I use just the things I want to...
The interesting about this script is that it can actually send commands to the Luxtronik. So in theory you should be able to change values through Domoticz...
See if I can make it work :)

Regards,
Patrick

Hi Wiljums,

It's working. You need to install nodered for it (and the other stuff for the luxtronik as well). (I only looked at setting values, not reading, though that works as well).

The only thing I made working is the + and - temperature setting. I made a virtual selector switch and every step runs a script from domoticz. Bit complicated, but I don't have the knowledge how to integrate it. You can have node talk to MQTT which talks to Domoticz, but really don't know how that works. I only needed the + and - temp setting, so it works...

The action on the selector switch in Domoticz:
script:///home/pi/domoticz/scripts/node/temp+10.sh

and the content of the shell script temp+10.sh:
node /home/pi/domoticz/scripts/node/temp+10.js
The temp+10.sh needs to be executable

and the content of the node script temp+10.js:
const luxtronik = require('/home/pi/node_modules/luxtronik2/luxtronik');

/* eslint no-console: "off" */
const pump = luxtronik.createConnection('192.168.200.145', 8888);

pump.write('heating_target_temperature', 1, function (err, data) {
if (!err) {
console.log(data);
}
});


The '1' after target temperature is the setting, so either 0,1,2,3,4,5 or -1,-2,-3,-4,-5
The luxtronik doesn't go beyond +5 or -5 degrees.

Good luck ;)
