vaillant-component

Please note that this component is still in beta test, so I may do (unwanted) breaking changes.

Ideas are welcome ! Don't hesitate to create issue to suggest something, it will be really appreciated.

Please download the vaillant folder and put it inside your custom_components folder.

You can configure it through the UI using integration. You have to provided your username and password (same as multimatic app)

It is strongly recommended to use a dedicated user for HA, for 2 reasons:

As usual for security reason, if your HA is compromised somehow, you know which user to block
I cannot strongly confirm it, but it seems vaillant API only accept the same user to be connected at the same time

Releases

1.1.0

Move everything to async
Bugfix for circulation (no considered on when hot water boost was activated)
Removed boiler temperature and boiler water pressure in favor of report entity (breaking change)
Better error handling
Automatic re-authentication in case of error

1.2.0

Adding a way to specify serial number in case you have multiple
some error log improvement/fix
adding some none check

1.2.2

Better error handling
Component does a reconnection every time an error occurs

1.2.3

Adapt to HA 0.110 deprecation/warning
Add some None-check in case of error when component is starting
Fix issue with set_holiday_mode (ValueError: unconverted data remains: T00:00:00.000Z)

1.3.0

request hvac update is not done by the component automatically. Instead, there is a new service request_hvac_update. If you have any issue with refresh time of the data, you can use an automation to call the service. I recommend to do it very 1 hour. If you really hove data refresh issue, you can do down until every 30min. Doing it more often will likely end up in an error at vaillant API. You can use something like this as automation:

- id: "Refresh vaillant data"
  alias: "Refresh vaillant data"
  trigger:
    - platform: time_pattern
      hours: "/1"
  action:
    - service: vaillant.request_hvac_update

1.3.1

check if a zone is enabled before creating a climate entity.

1.3.2

Fix the way the dynamic errors (coming from the API) are refreshed in order to have entities created/removed dynamically without restarting HA

1.4.0

Supporting cooling
BREAKING CHANGES on vaillant mode <> hvac mode & preset mode, please see Expected behavior below

Provided entities

1 water_heater entity, if any water heater: water_heater.vaillant_<water heater id>, basically water_heater.vaillant_control_dhw
1 climate entity per zone (expect if the zone is controlled by room) climate.vaillant_<zone id>
1 climate entity per room climate.vaillant_<room name>
1 binary_sensor entity binary_sensor.vaillant_control_dhw reflecting if the circulation is on or off
1 binary_sensor entity climate.vaillant_<room name>_window per room reflecting the state of the "open window" in a room (this is a feature of the vaillant API, if the temperature is going down pretty fast, the API assumes there is an open window and heating stops)
1 binary_sensor entity climate.vaillant_<sgtin>_lockper device reflecting if valves are "child locked" or not
1 binary_sensor entity binary_sensor.vaillant_<sgtin>_battery reflecting battery level for each device (VR50, VR51) in the system
1 binary_sensor entity binary_sensor.vaillant_<sgtin>_battery reflecting connectivity for each device (VR50, VR51) in the system
1 binary_sensor entity binary_sensor.vaillant_system_updateto know if there is an update pending
1 binary_sensor entity binary_sensor.vaillant_system_online to know if the vr900/920 is connected to the internet
1 binary_sensor entity binary_sensor.vaillant_<boiler model> to know if there is an error at the boiler. Some boiler does not provide this information, so entity won't be available.
1 temperature sensor sensor.vaillant_outdoor_temperature for outdoor temperature
1 sensor for each report in live_report (boiler temperature, boiler water pressure, etc.)
1 binary sensor binary_sensor.vaillant_quick_mode to know a quick mode is running on
1 binary sensor binary_sensor.vaillant_holiday to know the holiday mode is on/off
dynamic binary sensors if there are extra errors coming from the api.

Provided devices

1 device per VR50 or VR51
1 device for the boiler (if supported). Some boiler don't provide enough information to be able to create a device in HA.
1 device for the gateway (like VR920)
1 "multimatic" (VRC700) device (the water pressure is linked to the VRC 700 inside the vaillant API)
hot water circuit
heating circuit

For the climate and water heater entities, you can also found

the 'real vaillant mode' running on (AUTO, MANUAL, DAY, etc)

For the boiler error entity, you can also found

the last update (this is not the last HA update, this is the last time vaillant checks the boiler)
the status code (these can be found in your documentation)
the title (human readable description of the status code)

For the binary_sensor.vaillant_quick_mode, when on, you have the current quick mode name is available For the binary_sensor.vaillant_holiday, when on, you have the start date, end date and temperature

Provided services

vaillant.set_holiday_mode to set the holiday mode (see services in HA ui to get the params)
vaillant.remove_holiday_mode .. I guess you get it
vaillant.set_quick_mode to set a quick mode
vaillant.remove_quick_mode don't tell me you don't get it
vaillant.set_quick_veto to set a quick veto for a climate entity
vaillant.remove_quick_veto to remove a quick veto for a climate entity
vaillant.request_hvac_update to tell vaillant API to fetch data from your installation and made them available in the API

This will allow you to create some buttons in UI to activate/deactivate quick mode or holiday mode with a single click

Expected behavior

On room climate:

Changing temperature while ...

MANUAL mode -> it simply changes target temperature
other modes -> it creates a quick_veto (duration = 3 hours) (it's also removing holiday or quick mode)

Modes mapping:

AUTO -> HVAC_MODE_AUTO & PRESET_COMFORT
OFF -> HVAC_MODE_OFF & no preset
QUICK_VETO -> no hvac & PRESET_QUICK_VETO (custom)
QM_SYSTEM_OFF -> HVAC_MODE_OFF & PRESET_SYSTEM_OFF (custom)
HOLIDAY -> HVAC_MODE_OFF & PRESET_HOLIDAY (custom)
MANUAL -> no hvac & PRESET_MANUAL (custom)

On zone climate:

Changing temperature will lead to a quick veto with selected temperature for 6 hours (quick veto duration is not configurable for a zone)
