If you integrate inexpensive electric blinds, shutters or shutters into Home Assistant, you quickly run into a problem: many motors do not know their current position at all. They only know whether they are currently being raised or lowered. Home Assistant can then execute \u201eopen\u201c and \u201eclose\u201c, but cannot reliably indicate whether the blind is open at 30 %, 50 % or 80 %, for example. This is precisely where the integration Cover Time Based for Home Assistant<\/a> on. It supplements an intelligent position calculation based on the travel time and turns simple roller shutter motors into significantly smarter devices.<\/p>\n\n\n\n

The basic idea behind it is surprisingly simple: if, for example, a roller shutter takes 20 seconds to move completely from bottom to top, Home Assistant can use the elapsed time to calculate the approximate position of the roller shutter. If the motor runs for 10 seconds, the integration assumes that the roller blind has reached approximately 50 %. This creates a virtual position control, even though the actual hardware does not have any position sensors.<\/p>\n\n\n\n

So do you have an electric blind or shutter and want to integrate it into your smart home? With Home Assistant and the extension Cover Time Based<\/strong> you can control your roller blinds intelligently and check their exact position at any time. In this blog article, I'll show you how to make your roller blinds smarter, the Cover Time Based<\/strong>-extension and thus ensure more comfort in your everyday life.<\/p>\n\n\n\n
