B-Logicx for Home Assistant

Custom integration that connects Home Assistant directly to a B-Logicx NWM / NWX bus gateway — the BHS Home Server is optional and not a requirement.

Features

Switches (RLM / SoftM), dimmers, and read-only addresses (generic Set/Reset)
Covers (dual RLM) and Sfeer selection
AUD media players (sources, volume up/down, mute). BHS can control the physical player; that was tested with a NuVoP. NUV, AUD, ASD, and ART24 use the same bus shape. Full control can also go through Home Assistant; that was tested with Spotify and should work with any player Home Assistant can link. A known source, play, stop, or mute is written back so the DSM displays follow.
SoftM virtual status module (VSM) inside Home Assistant
TCP bus repeater — share the single NWM link with BLConfig / blxmonitor
RTC sync (incl. DST), LDM light sensor, TSM thermostat, WSM wind speed (km/h), BM8 doorbell
YAML import/export of addresses

About this project

B-Logicx is a Belgian home-automation vendor (Heist-op-den-Berg). Their bus uses EIB/KNX cabling and 24 V DC (black = 0, red = +24 V, yellow = bus signal). The system is decentralised by nature and makes it easy to spread the building blocks (inputs and outputs) through a building. An important advantage of B-Logicx is that everything is powered over the bus, and that (within certain limits) a single 24 V supply is enough. The protocol is simple: each datagram is two bytes (command + group, address).

Later installations

The problem I have found more and more over recent years is that newer, usually wireless, home-automation products make classic systems such as B-Logicx or Niko Home Control feel dated, because installation is simple. Wireless products do have the drawback that they often run on batteries, but they are much easier to fit, often without much experience, which makes them especially attractive for later installations.

Hybrid

This project means you do not have to choose: it lets an existing system become a hybrid. By letting B-Logicx talk to Home Assistant, it lets you install Zigbee, Z-Wave or Shelly where that makes the installation much simpler, without that becoming a second, parallel system beside the existing B-Logicx.

The official B-Logicx way to connect to Home Assistant is too limited, and it also requires a B-Logicx Home Server.

This integration works only through a network module that every system already has, and it provides seamless, real-time communication between B-Logicx and Home Assistant.

Important

This integration was produced independently. I am not affiliated with B-Logicx.
BLConfig remains required to program hardware; this HA integration monitors and controls the bus after it is configured.

I built this originally for my own use, and to help keep B-Logicx from becoming obsolete as newer systems appear.

In my view Home Assistant is the engine of The Internet of Things; things that do not integrate with it (well) will disappear over time.

I manage a large number of buildings where B-Logicx is installed; for me this is how those buildings avoid having to be refitted with other home-automation systems anytime soon.

I put the code online to help make B-Logicx more future-proof, and to get in touch with other B-Logicx users. How widespread is this system? Let me know!
