They use the same app, so you can switch between a Homey Bridge and Homey (pro) the same as you would switch between 2 normal Homey’s from withing the mobile app and web app.
You can have as many bridges in your home as you want, but they won’t work together natively, they will be separate devices (it is a cloud bridge, not an extender)
- your Homey bridge is already in the cloud, so no cloud backup is needed.
- Homey bridge and normal Homey are 2 entirely different devices, you would copy a flow the same way as you would from 1 normal Homey to another (manually)
All apps that are made by verified developers are possible to be used on the cloud Homey (if updated by the said developer), so check the appstore if the app is made by a verified developer to see if it is possible to be used on the cloud Homey (/bridge)
The PCB is an entirely new design, and all the processing is done in the cloud, so any previous experiences of zigbee and z-wave is kinda irrelevant.
Infrared has a mayor update on the bridge, including a way bigger database.
