If you're bored with a smart home that just has to download a specific app to control a light, here's the good news: Openhab can give you the most flexible control of smart home, Openhab is a mature, open source home automation platform that can run a lot of software, There is no agreement, which means it can now be connected to almost all of the home automation hardware on the market.Here we will show you how to install and launch the free smart home system.We first use
accessNow you need to access the Openhab system on the same local network, but what if you want to control your device and check the sensor outside of your Wi-Fi range? Then we need to set up remote access – The simplest way is to use the My.openhab Web service, which bypasses port forwarding and router configuration. The My.openhab service also has a IFTTT channel that allows you to remotely control and automate.Install the binding first. If you don
