Using remote_homeassistant with Nabu Casa

I have Home Assistant setup at my cottage and home. I would like to link the two using the remote_homeassistant custom component.

I use Nabu Casa to access the cottage instance of Home Assistant remotely.

I can not seem to be able to configure remote_homeassistant to use Nabu Casa.

Should work just fine. Use your nabu casa address, port 443 and check the secure box.

Do mean like this?

    - host:
      port: 443
      secure: true
      verify_ssl: false
      access_token: xxxxxxxxxxxxxxxxxxxxxxxx
      entity_prefix: "KLN_Remote_"

I get the following error:

The above exception was the direct cause of the following exception:

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    info = await validate_input(self.hass, user_input)

    raise CannotConnect()

That should work. If you omit verify_ssl or set it to true instead?

did you find a solution?
I also use remote homeassistant and it’s not difficult to connect a remote server with a white ip, but it won’t work through the nabu casa service.

Is it really suppsed to work with nuba casa? If it is and if someone knows how to get it running it will solve my current problem without having to buy new HW:-)

Edit: Yes it works like a charm!! Now in full control of our summer house from my main HA at home! Only to make sure to use ssl and port 443.


Would you mind sharing a step-by-step?

Also trying to get this working and no luck yet. My primary and secondary are both on Nabu and I can’t connect to the remote hub.
