We have started publishing OTA updates to the Homey Test App:
For clarity, the white series is handled by the CSA and Homey has supported updates through that process for a while. They recently released an update for OTA via Zigbee and Z-Wave which need to be added to the app on an individual basis. So far, in the test app, we have the VZM32-SN and VZW32-SN beta firmware updates. I will be adding more down the road, but if anyone has any feedback, please let me know.
