The Cloud/Bridge is an entry-level home automation solution, it works with most popular brands (at least popular in NL/EU) and is cheap. It’s also limited: apps that provide support for local networked devices, or offer useful tools (timers, logging, database support, Homeyscript, Homekit, etc), are not supported by the Cloud/Bridge (and probably will never be supported).
There’s also a dependency on a good stable internet connection. If you don’t have one, you may run into automation issues with Cloud/Bridge because nothing is run locally.
If you want a (mostly) local solution that supports all Homey apps, you need a Homey Pro.
