Help with HomeSeer HS4 Device node in Node-RED Add-on

A little background. I’m slowly moving from HomeSeer HS4 to Home Assistant and one of the things that is helping a lot is using Node-RED as a bridge between the two. I’m using the node-red-contrib-homesser device and event nodes along the the node-red-contrib-home-assistant-websocket event:state and action nodes.

My flows all work great in an instance of Node-RED that is running independant of Home Assistant, but won’t work in an instance of Node-RED running as an add-on.

The issue appears to be with the HS4 webhook. Node-RED has port 1880 exposed to core so the HS4 webhook would be something like http://<server_ip>:1880/homeseer/webhook but I don’t get any device status updates when running in an add-on. When I put that URL into a browser, I get probmpted for a username/password which I’m pretty sure is causing the problem. There is no way to add credentials to the HS4 webhook.

Has anyone else run into this and figured out how to make it work?

I did some experimenting with auth_providers and trusted_networks and trusted_users but wasn’t able to get passed the login prompts for the webhook. I’m starting to think running NR as an add-on isn’t a good option for me.
