Module usage

The project is separated in two layers:

1. ApiConnector

This is the low level connector using the vaillant API and returning raw data directly coming from the API (basically, json formatted responses. The connector is handling the login and session. The connector able to reuse an already existing session (cookies). Two files are saved (cookies and serial number of your installation) on the file system. Default location is: ~/.vr900connector but it can be overridden. Files are named .cookies and .serial.

Here is an example how to use it:

from vr900connector.api import ApiConnector, urls
   
connector = ApiConnector('user', 'pass')
connector.get(urls.facilities_list()) 

to get some information about your installation, this returns the raw response, something like this:

{
    "body": {
        "facilitiesList": [
            {
                "serialNumber": "1234567891234567891234567890",
                "name": "Name",
                "responsibleCountryCode": "BE",
                "supportedBrand": "GREEN_BRAND_COMPATIBLE",
                "capabilities": [
                    "ROOM_BY_ROOM",
                    "SYSTEMCONTROL_MULTIMATIC"
                ],
                "networkInformation": {
                    "macAddressEthernet": "12:34:56:78:9A:BC",
                    "macAddressWifiAccessPoint": "34:56:78:9A:BC:DE",
                    "macAddressWifiClient": "56:78:9A:BC:DE:F0"
                },
                "firmwareVersion": "1.1.1"
            }
        ]
    },
    "meta": {}
}

Basically, you can use

from vr900connector.api import ApiConnector
   
connector = ApiConnector('user', 'pass')
connector.get('') 

with urls from vr900connector.api.urls

I would recommend using this layer if you only want to retrieve basic data (outdoor temperature, current temperature, etc.)

2. SystemManager

This layer allows you to interact in a more friendly way with the system and compute some data for you. The underlying ApiConnector is hidden and raw responses are mapped to more useful objects.

Here is an example:

from vr900connector.systemmanager import SystemManager
from vr900connector.model import OperatingModes
   
manager = SystemManager('user', 'pass')

# get the complete system
system = manager.get_system()

# set the hot water target temperature to 55
manager.set_hot_water_setpoint_temperature('dhw_id', 55)

# set the zone operation mode to 'AUTO'
manager.set_zone_operation_mode('zone_id', OperatingModes.AUTO)

The main object to manipulate is vr900connector.model.System, which is grouping all the information about your system.

I would recommend using this layer if you want to do more complex things, e.g: if you want to get the target temperature for a room or a zone, it can become a bit complex since you have to deal with holiday mode, quick mode, quick veto, time program, etc. This layer is hiding you this complexity.

Todo's

• Move ApiConnector to async
• Handling ventilation
• Handling missing information when VRC700 (and/or boiler) is shutdown (e.g. TimeProgram are not coming anymore from the API if boiler is down)
