Publish to multiple MQTT hosts?

[rucknapucknavitz]

I wonder if it’s possible to publish to multiple mqtt hosts? I have a local HA instance, but then another global instance that connects to all the local networks via tailscale - so the local container would theoretically publish to the tailscale address of the global HA, too.

I’m running the docker container and thought I could just add a second instance, but quickly realized that only one instance can claim the sdr on the USB bus.

I’d welcome any ideas. Thanks!

Edit: in the meantime I can pull the entities across using this integration: https://github.com/custom-components/remote_homeassistant
