Home-Assistant, Homematic, Homegear & CUL on K8s

In order to use Home-Assistent with CUL-Stick, you'll need homegear. To integrate homegear into HASS you'll need the additional addon "HomeMatic". Sadly HASS does not support addons when using containers. So this is a quite hacky way to make it work on Kubernetes.

Kubernetes#

I'm using the Helm-Chart from k8s-at-home. You can find my values here

Setting up Homegear#

Make sure /etc/homegear/families/max.conf is configured for your device:

[CUL]
id = My-MAX-CUL
default = true
deviceType = cul
device = /dev/ttyUSB0
responseDelay = 40

Login to container & enter homegear shell using homegear -r.
Select "MAX!" Family using fs 4
Enable peeing mode pon & peer your device[s]
List peers ls
You can rename them, too using pn <DEVICE-ID> <NEW-NAME>

Homematic Addon#

In the container create /data/options.json like this:

{
    "rf_enable": false,
    "rf": [
      {
        "type": "CCU2",
        "device": "/dev/ttyAMA0"
      }
    ],
    "wired_enable": false,
    "wired": [
      {
        "serial": "xy",
        "key": "abc",
        "ip": "192.168.0.0"
      }
    ],
    "hmip_enable": false,
    "hmip": [
      {
        "type": "HMIP_CCU2",
        "device": "/dev/ttyUSB0"
      }
    ]

Configure Home-Assistant#

Add this snippet to your configuration.yaml of home-assistant:

homematic:
 interfaces:
  wireless:
   host: localhost
   port: 2001
   resolvenames: metadata

Finishing up#

After restart, you should find your Homegear devices in the entities of HASS.
