Tailscale - remote access without public IPRating:
80%
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.
Shelly vs OpenHABRating:
80%
The Shelly brand is known for its products that primarily communicate over WiFi, including smart plugs, relay switches, blinds control relays, and many other devices. One of the advantages for deployment is the ability to both read and control these devices using the universal MQTT protocol. Across existing add-ons for both OpenHAB and Home Assistant, we will demonstrate how to use Shelly devices without installing any additional extensions.
Victron vs Smart HomeRating:
0%
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.
Smart Home vs GoodWeRating:
50%
In the post, we will demonstrate step by step how to communicate directly with the GoodWe inverter in a smart home setup and obtain real-time information (unlike the SEMS portal). This information is essential if we want to react to current parameters in a smart home, such as activating additional cooling or controlling a socket with a various load.
Voice control of the houseRating:
60%
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 this series, we will look at the step-by-step setup of MikroTik devices for home users or a small business (up to 25 people). In the first article, we will focus on the initial setup - we will download Winbox and set up DHCP for the primary network and guest network. Similarly, we will also adjust the WiFi settings.
Alarm from existing PIR sensors in a smart home.Rating:
0%
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.
