Once you have an electrician install the Glass Light Switches and you Nature Mini Touchscreen, you can add the rest of the components yourself. A typical use of this kit would be for your Living/Dining/Kitchen area to allow scene control for lights, coloured LED strip lighting under a bench, trigger a scene or alert when a window or door is opened, remotely check the temperature of your home and set schedules to turn on and off lighting automatically.
This is a great way to get a start in automation. With this kit it is very simple to add more automation to your smart home in the future.
