Indigo Domotics

I get the following error when trying to start the plugin:
“EPS HomeKit Bridge.indigoPlugin” cannot be opened because the developer cannot be verified.

I've tried going to system prefs and security and having it "open anyway", but no change.
This is Big Sur Beta 5

same thing happens with Beta 6 - can't get around security protection

Have you tried clearing the quarantine flags on all the plugin files via these steps?

Thanks - that did the trick.
Now the server is running, but Home (iOS or MacOS) does not recognize the devices - doesn't seem to be responding to server, but hard to really tell.
