lcn integration for Home Assistant allows you to connect to LCN hardware devices.
The component requires one unused license of the coupling software LCN-PCHK (version >2.8) and a LCN hardware coupler. Alternatively a LCN-PKE coupler can be used which offers two PCHK licenses. With this setup sending and receiving commands to and from LCN modules is possible.
There is currently support for the following device types within Home Assistant:
To use your LCN system in your installation, add the following lines to your
You have to specify at least one ip/port with login credentials for a PCHK host.
Consider to store your credentials in a secrets.yaml.
lcn: connections: - name: myhome host: 192.168.2.41 port: 4114 username: lcn password: lcn lights: - name: Bedroom light address: myhome.s0.m7 output: output1 dimmable: true transition: 5
(map)(Required)List of your connections
(string)(Required)IP address of the LCN-PCHK host.
(integer)(Required)Port of the LCN-PCHK host.
(string)(Required)Login username for the LCN-PCHK host.
(string)(Required)Login password for the LCN-PCHK host.
(string)(Optional)Optional connection identifier. If omited, the connections will be named consecutively as pchk, pchk1, pchk2, …
Default value: pchk
(integer)(Optional)Segment coupler scans. Increase this number if you have at least one segment coupler in your system.
Default value: 0
(string)(Optional)Dimming mode for connected modules. The operation mode is programmed into the LCN modules by the LCN-PRO software and depends on their firmware. If you experience unexpected dimming behavior, the connection is probably in the wrong operation mode. Possible values: steps50, steps200
Default value: steps50
(map)(Required)List of your lights.
(string)(Required)Name of the light.
(string)(Required)Address of the module/group.
(string)(Required)Light source (OUTPUT_PORT).
(bool)(Optional)Enable the dimming feature for this light
Default value: false
(int)(Optional)Transition (ramp) time in seconds.
Default value: 0
LCN hardware devices connected to the LCN bus are called modules. LCN modules are addressed by their numeric id in the range (5..254).
Modules can be arranged in segments. Segments can be addressed by their numeric id (5..128) or 0 (= no segment exist) or 3 (= target all segments).
LCN Modules within the same segment can be grouped by their group id (5..254) or 3 (= target all groups.)
The LCN component allow the connection to more than one hardware coupler. In this case it has to be specified which hardware coupler should be used for addressing the specified module.
Whenever the address of a module or a group has to be specified, it can be addressed using one of the following syntaxes:
Example for modules:
connid.s000.m007 connid.s0.m7 s0.m7 0.7
Example for groups:
connid.s000.g007 connid.s0.g7 s0.g7 0.g7
Leading zeroes in the segment id or module/group id can be omitted. If the
connection_id is omitted, the first connection defined in the configuration will be used.
The platforms and service calls use several predefined constants as parameters.
