The Tailscale service solves access between individual devices if you don't have a public IP address. It's free for one user with support for up to 100 devices. We'll show you how to install Tailscale on a Raspberry Pi that you'll have at home and on a client (Android, iPhone) from which you'll want to access the home Raspberry Pi. Our example will be remote access to OpenHAB running on a Raspberry Pi. However, the same setup applies to many other applications - home NAS, PiHole, Home Assistant, Domoticz, NextCloud, and others.

In this post, we will show you how to retrieve information from a photovoltaic power plant by Victron. We will connect to the Cerbo unit via MQTT. Based on these values, we can control various appliances (heating, boiler, etc.) and prevent the battery from being drained when they don't need to be.

In this article, we will connect the Amazon Echo Dot voice assistant with open source home automation. We won't be using OpenHAB Cloud, so everything runs locally. In this case, a few additional settings are necessary, but the result is worth it!

In a your smart home, PIR sensors may not only be used to switch lights on and off based on motion, it is possible to utilize these sensors to detect the presence of motion in a particular room. This information can be used to create a relatively reliable uncertified home security system. In this guide, you will find the logic for how this can work in the OpenHAB software in our model smart home.
