I recently moved Homebridge to another server, a Pi 5. Node-red is still on the server (a Pi 4B) where the other Homebridge was. I stopped that HB service, but NR says it can't find HB with the old MAC address. And I changed all HB events to use the new Pin, not the old one.
All HB events are tagged with the new Pin, but NR doesn't see any HB events coming in. It just complains that HB was not found at . ???
