Troubleshooting webhook issues

[devanb]

So, I have failed to realize that my webhook updates are not being registered in node-red for 2 years. I started using sync nodes at the beginning and never realized something was broken.

Fast forward to a week ago and found it's broken.

I have two HS4 servers connected via VPN and all work well. The remote webhook works and the local one does not. Really weird.

To be clear, if I update a device on the remote HS4 web interface, the associated node in node red will update the status for the remote device but the same behavior does not work on the local HS4 instance..

I did a packet capture on the node red (local HS4) device and am receiving packets from both the localhost address and the remote address.

Can anyone suggest any other troubleshooting paths? I'm out of ideas.

Thanks,

Devan

Here are the packets received by the device running node red and the local HS4 instance:

There is a known problem if you have 2 HS servers in Node Red, and one of them is running on the same machine as Node Red

Try to to configure your local HS server in Node Red as 127.0.0.1

Thanks for the update. I was going crazy.

The hs-server on node-red is currently configured as 127.0.0.1.

If possible, the comments in the linked code should be added to the help section of the homeseer nodes in node-red. It could save some folks a lot of troubleshooting.

I guess the only workaround is to separate the node red server. That's a pain for me.

If you come up with any other work arounds or want me to test the multi-hs4 issues, let me know.

Thanks,

Devan
