Viessmann Component

[stefanwi (Stefan)]

Things that I did (have installed HA in Python venv on my raspi 4 4GB):

Updating PyViCare to 0.1.10:
Login via shell then change user to homeassistant, and enter Python venv:

sudo -u homeassistant -H -s
cd /srv/homeassistant
source bin/activate

Now update PyViCare:

pip3 install --upgrade PyViCare
exit

Now clone ha_vicare custom component (https://github.com/oischinger/ha_vicare) from git:

cd ~
sudo git clone https://github.com/oischinger/ha_vicare.git

Now move downloaded folder into homeassistant custom component folder:

mv ha_vicare/vicare /home/homeassistant/.homeassistant/custom_components

Then restart HA and it will automatically choose the custom component instead of the official.

@oischinger: I saw, that SCAN_INTERVAL = 900 secs. which was introduced 8 days ago, is still alive in code. Is that correct? I thought, that from version 0.1.10, PyViCare will manage that the Viessmann api will not be fired with requests. Thanks for a short statement.

[oischinger (Oisch)]

@Tommmii
Installing it is super-simple: Just download the files in here: https://github.com/oischinger/ha_vicare/tree/master/vicare and put them under HOME_ASSISTANT_CONFIG_DIR/custom_components/vicare

On startup you will get a log entry in Home Assistant that vicare is a custom component and might not have been tested, etc.
You will also notice it because the update frequency of the ViCare data is higher if you plot it on a graoh

[oischinger (Oisch)]

Thanks for the hint with the SCAN_INTERVAL=900. I fixed that now on master.

Note that you should not have to manually update to pyvicare 0.1.10. In my case Home assistent did that for me because I added it to manifest.json

[stefanwi (Stefan)]

Ah okay, thanks for information. I didn’t knew, that HA will update to version concerning manifest.json

[Tommmii]

@oischinger

Just download the files in here: https://github.com/oischinger/ha_vicare/tree/master/vicare and put them under HOME_ASSISTANT_CONFIG_DIR/custom_components/vicare

Is adding vicare: to the yaml configuration needed, or is the custom component added via the Integrations page ?

[Tommmii]

well, something isn’t working as expected, values don’t update.

My yaml config :

vicare:
  username: !secret vicare_email
  password: !secret vicare_password
  heating_type: gas
  scan_interval: 60

[oischinger (Oisch)]

This is a failure of a sensor that is not from my integration: sensor.vicare_heatcurve_target_temperature

Does the integration also fail?

[Tommmii]

Yours didn’t refresh, but then I saw above that the 900s interval was still hardcoded.
Updated to the newer version, seems ok now.

I did get the sensor.vicare_heatcurve_target_temperature from you, indirectly :

Making use of template sensors and the Home Assistant Vicare integration

[oischinger (Oisch)]

The sensor.vicare_heatcurve_target_temperature seems to not cope well with None-values, which occur when there was no update from the servers yet.
The template can be written differently. Once I find some time I’ll upload some better yaml examples for monitoring with individual sensors.

[Tommmii]

So far so good, on the custom component, 24hours with scan_interval: 60 and no ban from VSMN.

[stefanwi (Stefan)]

Same here. Works good so far…

[oischinger (Oisch)]

I created a PR towards the next home assistant release. So expect this to be integrated soon.

I also documented the scan_interval feature explaining a little bit Viessman’s rate limits and the consequences here:

home-assistant/home-assistant.io/blob/36b2422aa1aae5911c3439809583a49f6742bbc8/source/_integrations/vicare.markdown#viessmann-api-limits

[Tommmii]

Good work , thank you !!

Just letting you know ; something went wrong with the formatting of the Configuration chapter on the Github docs page.

[Sangoku (Sinisa Culic)]

I cant get the sensors to show up i used the config:

sensor:
 platform: template
 sensors:
   vicare_outside_temperature:
        friendly_name: "Vanjska Temperatura"
        unit_of_measurement: '°C'
        value_template: "{{ state_attr('climate.vicare_heating', 'outside_temperature') }}" 

   vicare_inside_temperature:
        friendly_name: "unutrasnja Temperatura"
        unit_of_measurement: '°C'
        value_template: "{{ state_attr('climate.vicare_heating', 'temperature') }}"

type is:
heating_type: heatpump

No logs, no errors just gets stuck on no data. Any idea what i could have done wrong?

Temparature display works without problems and heating pump also… so no idea what i am missing.

[realfire]

I can just write you for vicare. They kicked me out (maybe you too ?)

4 weeks ago they wrote me an email that they will check the API IFC because to many calls -_- 1 week ago they said they gonna turn it down.

[Tommmii]

we all got that email, no one got permanently banned. 24 hour ban is the max they handed out.

@Sangoku , do you have the vicare: integration configured ?

[Sangoku (Sinisa Culic)]

ofc.
How water and hearing are working.
only part that remains broken is the template.

Update. Just checked error logs and we have some winners. here is whole log.

Here is in text form. makes more sense

Hello,
I have a vitoconnect 100 wifi.
Did you manage to get the preset_mode to work ?
I choose eco or comfort from the lovelace thermostat or service set_preset_mode nothing happens.
thanks you

[Klex1404]

Doesn´t work for me either.

[Tommmii]

your config is very similar to mine,
notable differences are you have a Name in the vicare integration, and you have no water_heater configured.

Here’s mine, that works just fine these last days :

vicare:
  username: !secret vicare_email
  password: !secret vicare_password
  heating_type: gas
  scan_interval: 120
#
water_heater:
  platform: vicare
#
sensor:
  - platform: template
    sensors:
      vicare_outside_temperature:
          friendly_name: "Vicare outside"
          unit_of_measurement: '°C'
          value_template: "{{ state_attr('climate.vicare_heating', 'outside_temperature') }}"
      vicare_desired_temperature:
          friendly_name: "Vicare target"
          unit_of_measurement: '°C'
          value_template: "{{ state_attr('climate.vicare_heating', 'temperature') }}"
      vicare_heatcurve_target_temperature:
        friendly_name: "Vicare heatcurve target "
        unit_of_measurement: '°C'
        value_template: "{{ state_attr('climate.vicare_heating', 'temperature') + state_attr('climate.vicare_heating', 'heating_curve_shift') - state_attr('climate.vicare_heating', 'heating_curve_slope') * (state_attr('climate.vicare_heating', 'outside_temperature') - state_attr('climate.vicare_heating', 'temperature')) * (1.4347 + 0.021 * (state_attr('climate.vicare_heating', 'outside_temperature') - state_attr('climate.vicare_heating', 'temperature')) + 247.9 * 0.000001 * (state_attr('climate.vicare_heating', 'outside_temperature') - state_attr('climate.vicare_heating', 'temperature')) * (state_attr('climate.vicare_heating', 'outside_temperature') - state_attr('climate.vicare_heating', 'temperature'))) }}"
      metno_outside_temperature:
        friendly_name: "Met.no outside"
        unit_of_measurement: '°C'
        value_template: "{{ state_attr('weather.home', 'temperature') }}"

Perhaps try to adjust those 2 main differences ?
