Basic - OpenHAB on Raspberry Pi

 

The heart of the intelligent house is the OpenHAB project, which runs on Raspberry Pi board. In this article, we will prepare image, launch OpenHAB and set up basic services. This will give us a stable base whether we use wired sensors, relays or wireless standard like Z-Wave, etc.

Extension - Control power circuit

 

Switching power circuits - sockets, lights, blinds, pumps and other devices under 110-230V is one of the essential functions of an intelligent house. At Pi-Home, we are using Arduino Mega boards with Ethernet Shield, which control Arduino's compatible SSR relays connected with high power relays of the switchboard. More information and detaied scheme can be searched in the article.

DALI device control via MQTTRating: 
0%

DALI (Digital Addressable Lighting Interface) is an open interface for lighting controls in the home, industrial buildings, public objects, etc. To connect to our OpenHAB system, we can use a commercial converter from ADFWEB called HD67941-B2 - DALI / MQTT - Converter. In the article, we will show how to use this converter in conjunction with MQTT.

In this article, you can find how to solve the measuring the water level in the reservoir (e.g. rainwater reservoir). The values are converted into the volume in liters. This enables you to fill the volume tank when needed or predict any other situations.

Advanced PIR sensors features in OpenHABRating: 
0%

The HC-SR501 PIR sensor contains mechanical adjustement for detect range and time. But in an intelligent house, we want to be able change time how long the light will be active and change whether the light will be controlled by PIR or not. Below it's shown how to program the PIR sensor to enable this features.

Video intercom Doorbird in OpenHABRating: 
0%

Native support for OpenHAB is provided by video intercom by Doorbird company. The solution is powered and connected by a UTP cable and has its own IP address to make it easier for you to install at the gate. OpenHAB is then able to import images from the intercom, visit history, manage gate opening on the button and by the phone, do not disturb feature during night, alarm feature etc. In the instructions we guide you how to use OpenHAB with Doorbird D101.

Local weather station allows you to track the exact direction and speed of the wind, the amount of rainfall but also the intensity of the sun's radiation. This information can be used, among other things, to protect interior of the house from the sun or wind and to decide on the garden irrigation. We will show you how connect commercial weather station with OpenHAB.
