Node-RED and Home Assistant running in different namespaces

[rjdza]

I have Home Assistant running under docker (with the HACS Node-RED companion installed).

Node-RED is running directly on the host, with the contrib nodes installed.

Is this a supported configuration? If so, is there a reason it doesn't see the hass client?

If not, is there a workaround? How does the components communicate?

Finally, not really related, occasionally (frequently) when I deploy, one or two nodes say they cannot communicate with the server. Is there a solution to this, or will I have to downgrade to 0.52?

Thanks in advance.

If the host you have NR installed can access Home Assistant it doesn't really matter where each is installed.

If you referencing the call-service node it is because your flows are getting to the call-service node before NR has connected to HA. Try changing your deploy method to "Modified Nodes".

Please excuse me if this is a stupid question then (I have googled and searched the docs). How do I connect node-red to the plugin?

Things work when I connect to the url, but when I choose to use the HA plugin there are no further config options and nothing works :\

What is the "plugin"? The Node-RED companion custom component? If so, you don't connect to it. You add it to HA using the integration menu.

I have the Home Assistant add-on installed under Home Assistant, and the installation documentation says all configuration is done in node red, but when I add a HA server in node-red and tick the "I Use The Home Assistant Add-on" there are no further configuration options - where do I tell node-red how to connect to the add-on?

(Thanks for the help, btw.)

If you're running NR on the host machine you are not using the Node-RED addon https://github.com/hassio-addons/addon-node-red

As I mentioned in my initial post, I did install the Node-RED addon using HACS, and then added it as an integration, so Home Assistant is definitely running it..

As to whether I'm running it on the host, that's a complex question, also mentioned in my initial post - I'm running Node-RED on the host, but I'm running Home Assistant in a docker instance, which means it's the same physical machine, but potentially a different machine since it's running in a separate namespace (basically a virtual machine).

How am I supposed to run the companion and integrate Node-RED?

What you installed from HACS is not an "add-on" it's a custom component. Add-ons are docker containers built to work closely with the Home Assistant supervisor.
