I’ve been using a v1 hub for several years and just got a v3 hub for zwave plus and zigbee compatibility with cheap aquara sensors. I have several smart apps in use along with alexa integration. What is the recommended path for a slow migration of the devices and automation from my v1 to v3 hub. I have about 80 devices (a combination of zwave, zigbee, hue and virtual devices). I do heavily use groovy custom device handlers and apps.
Specifically, I’ve read some bad stories about having two hubs on the same account at same or different “locations”. What is the best way to set up the 2nd hub?
