@Simon_Willis If you would have gone on Github to create an issue regarding the AUS Product Id as suggested above, you would have found that there is already an issue created a couple of weeks ago describing the same behaviour you experienced with latest beta. So it is a known problem with latest beta.
This forum is not actively monitored by Athom, so please visit Github and under the above issue, write your experience, too. Describe as much detail as possible including Homey’s firmware version, Aeotec app beta version etc.
In regards with Vera interfering with Homey. Theoretically, no! Imagine a block of appartments where everyone owns a z-wave controller.
