0.78.3 Volkszaehler

[chriscohnen (Chris)]

I was using Rest to fetch the data from my volkszaehler installation and that is working

• platform: rest
  name: vzLoggerT
  resource: http://192.168.188.85:8080
  value_template: ‘{{ value_json.data[0].tuples[0][1] }}’
  unit_of:measurement: “Wh”
• platform: rest
  name: vzLoggerC
  resource: http://192.168.188.85:8080
  value_template: ‘{{ value_json.data[1].tuples[0][1] }}’
  unit_of:measurement: “W”

but when trying the new volkszaehler sensor it is not working
e.g.

• platform: volkszaehler
  host: 192.168.188.85
  port: 8080
  uuid: ‘fde8f1d0-c5d0-11e0-856e-XXXXXXX’
  monitored_conditions:
  • average

did somebody get it working

I only get an error in log
documentation also does not tell me which uuid to take. there is one for the total sum and one for the current watts …

Any help appreciated thanks,
Chris

I tryed this example on the homepage from home assistant.
With the uuid: from volkszaehler.org.

Example configuration.yaml entry

sensor:

• platform: volkszaehler
  host: demo.volkszaehler.org
  uuid: ‘57acbef0-88a9-11e4-934f-6b0f9ecd95a8’
  monitored_conditions:
  • average
  • consumption

I see a traceback during startup but the underlying module seems to work fine.

Have you an Idea what i could do ? or is the Problem on Volkszaehler.org ?
i got these errors but i don´t know how i can solved it.

@Phoenix I got exactly the same error because I added the port behind the ip address(host: 192.168.1.x:8080) but the port address must be in a separate line! See https://www.home-assistant.io/integrations/volkszaehler/

But now I might have the same problem as the author of the thread. I get the following error message:

Anybody got any ideas why this happens ?

[Visi (Bastian Fricke)]

If i use the ip adresse instead the hostname it works fine

 - platform: volkszaehler
    host: 192.168.0.1
    uuid: 'enter your uuid'
    monitored_conditions:
      - average
      - consumption
      - min
      - max

Have fun!

I have the same Problem:

Now, after a few Restarts it works.
But the values differ from the Volkszähler web interface

Hello,

Unfortunately I was not lucky with multiple restarts.
Could you share your configuration one more time?

Is someone working on this bug?

Hi,
I did not like to have the middleware running and only connect directly with vzlogger (via MQTT). You can setup mqtt in the vzlogger.conf and use the Mosquitto Addon in homeassistant. See also my post here:

Smart meter with vzlogger/live energy use as a sensor

Hi, I also setup vzlogger with home assistant. I am using a USB IR dongle that I bought. Software-side I created a Docker with the newest vzlogger (see pull request https://github.com/volkszaehler/vzlogger/pull/448 ). This is helpful to avoid having all dependencies and scatter install files in my Raspi, so I can run it along my other docker stuff. used MQTT to pass data to the Mosquitto Broker Addon and from there pulled it directly into Homeassistant. (before that I used http push -> …

This setup is so far very stable.

Hi,

i have the same issue first then i tried out demo[dot]volkszaehler[dot]org and this works fine for me.

The difference to my volkszaehler instance was i do not setup a proxy.

In the URL to access volkszaehler on my raspberry pi the “middleware.php” is not possible but the volkszaehler integration use url with middleware.php (check line 11 in python-volkszaehler/volkszaehler at c7a683c29900ba3ea0ef01597af697dd94bc18a9 · home-assistant-ecosystem/python-volkszaehler · GitHubinit.py).
I setup a nginx proxy for my volkszaehler then integration start works fine.

Url have to have this format:
{{protocol}}://{{ip-address}}/middleware.php/data/{{uuid}}.json

Wrong url is (without middleware.php):
{{protocol}}://{{ip-address}}/data/{{uuid}}.json

On the volkszaehler page is a configuration sample for a nginx proxy i used:
