This is a product for prosumers and people who enjoy experimenting with smart home devices.
NOT for the 'ordinary consumer'.
The hub supports various protocols. Many brands have a so-called 'app' available so that the hub can communicate with the accessories. Before purchasing, first check whether the accessories you want to connect are supported. Please note that although an accessory is supported, this does not mean that all functionalities of the accessory in question are supported. For example, a button that supports short, short, short, long pressing can only detect in the Homey app for the relevant accessory that it has been pressed, not in what way. This also varies from brand to brand, and accessory to accessory.
You can create very sophisticated automations. If you can program, there are even more possibilities! Interesting automations can be made even without programming knowledge, but you have to enjoy sitting down to do this.
All in all a very nice device, but NOT plug and play.
