Bayernlüfter Custom Component

A custom component for controlling the Bayernlüfter (Bayernluefter) via home-assistant. The Bayernlüfter needs to have a WiFi-Module and additional humidity sensors installed (either the original WiFi-Module and Sensors or the DIY option).

The component enables controlling the fan, monitoring humditity and toggling Power and Timer mode.

You can configure this device as a top-level entity, and it will add all sensors and switches for above mentioned features.

# Example configuration.yaml
bayernluefter:
    resource: http://192.168.178.5
    scan_interval: 30 # Optional scan interval in seconds

If you want to use several devices you can pass a list of resources. Each resource needs a unique name.

# Example configuration.yaml
bayernluefter:
  - name: Living Room
    resource: http://192.168.178.5
    scan_interval: 30 # Optional scan interval in seconds
  - name: Kitchen
    resource: http://192.168.179.6
    scan_interval: 30 # Optional scan interval in seconds

Installation

Copy into your custom_components directory or install via HACS

Debugging

In order to debug this component, it is possible to leverage the mock bayernluefter web server used for testing the component pyernluefter as an example endpoint. To use it, configure localhost:8126 as endpoint and run the following script.

from pyernluefter.tests.test_structure.bayernluefter_mock_server import BayernLuftHandler, BayernLuftServer
handler = BayernLuftHandler

max_retries = 10
r = 0
while not self.server:
    try:
        # Connect to any open port
        self.server = BayernLuftServer((ADDRESS, 8126), handler)
    except OSError:
        if r < max_retries:
            r += 1
        else:
            raise
        time.sleep(1)

self.server_control = Server(self.server)
self.port = self.server_control.get_port()
self.url = "{}:{}".format(ADDRESS, self.port)
# Start test server before running any tests
self.server_control.start_server()
