How to add a Homematic CCU on a different network?

Configuration
1

Hi all,

currently I’m using Openhab 2 for about 120 devices on our farm. Most of these are controlled by Homematic CCUs. I have two of them (they have a distance of 300 meters between them), and they are on a different network than the home automatic server.

Today I installed the latest version of HASS in a docker container of the server and it immediately started to detect stuff on the server’s network. That was fairly impressive. I also managed to add two DAIKIN ACs by adding the integration and defining their IPs (also on a different network). However I am stuck when it comes to the CCUs. I did not find a Homematic integration to add, only the Homematic IP cloud.

Can anybody give me a hint how to proceed ?

In addition: Can I add more than one CCU to HASS ?

Thanks for your thoughts - M.

You have to do the setup manually in the configuration.yaml file. Here’s the documentation.

And yes, by adding multiple interfaces you can add both CCUs. You might have to do some enhanced configuration for the CCU on the other network (callback_ip is what is coming to my mind here). And you have to ensure, that the gateway of the other network has the proper rout set to allow the CCU to connect to your Home Assistant IP (the callback_ip).
