This integration integrates BSBLan devices into Home Assistant.

BSBLan is a device that is made by Frederik Holst and Ulf Dieckmann for documentation and with the help of many other contributors. The new board v3 is designed for an Arduino Due with an Ethernet-Shield for web-based controlling of heating systems such as Elco Thision, Brötje and similar systems.

It can interface with the heating system over Boiler-System-Bus, Local Process Bus and PPS (Punkt-zu-Punkt Schnittstelle) For more information of which system it supports, have a look at their documentation.


Adding BSB-Lan to your Home Assistant instance can be done via the user interface, by using this My button:

For authentication HTTP authentication using a username and password, or using a passkey is supported. Use either one.

For more documentation of the BSBLan device, check the manual.
