ioBroker HomeMatic ReGaHSS Adapter

Number of Installations Number of Installations NPM version

Test and Release Translation status Downloads

Connects HomeMatic CCU "Logic Layer" ("ReGaHSS") to ioBroker.

This adapter uses Sentry libraries to automatically report exceptions and code errors to the developers. For more details and for information how to disable the error reporting see Sentry-Plugin Documentation! Sentry reporting is used starting with js-controller 3.0.


This Adapter keeps the HomeMatic CCU variables in sync with ioBroker and provides the possibility to start HomeMatic CCU programs from within ioBroker. Furthermore, this adapter can be used as a "migration helper": you can sync device/channel names, rooms, functions, and favorites from the CCU to ioBroker (this is one way only, changes in ioBroker will be overwritten once synced again – so deactivate this features after the first sync).


This adapter requires one (ore more) already installed and initialized hm-rpc adapter(s) to work.



What are the ALARM states created in the devices object?

States which end on '_ALARM' are created by the Rega adapter, to represent service messages. The alarm has three different states NO ALARM, which indicates that there is no related alarm (service message) for the state. When a service message appears for the related state the state will change to ALARM, containing the timestamp of the alarm occurrence on the CCU in the last changed timestamp of the state ( When you change the state in ioBroker, this will acknowledge the alarm in the CCU and the service message will be gone. The alarm state in ioBroker will change to ACKNOWLEDGED still containing the occurrence timestamp in the last changed state, and the timestamp when it has been acknowledged in the state's timestamp (state.ts).

I have a HomeMatic CCU2/CCU3, how can I add it to the adapter settings?

Within the adapter settings, you added the IP address of your CCU2, then

  • Activate "rfd" for regular HomeMatic devices,
  • Activate "HomeMatic IP" if you use HomeMatic IP devices,
  • Activate "Virtual Devices" if you use Groups in HomeMatic (so if you combine e.g., multiple thermostats to a group)

If I modify rooms, etc. in HomeMatic, the changes are not applied right away within ioBroker.

Please reload the hm-rega adapter instance, e.g., by clicking on the reload icon of hm-rega.x (actions table) in the Instances tab. Afterward, wait about 10-20 seconds and then check both the Enums tab and the Objects ( - make sure you enabled the expert mode). If the changes do still not appear, restart ioBroker. Then the changes should be available in ioBroker.

How can I sync the hidden/invisible variables, e.g., of HMIP-PSM?

Since version 2.4.0, it is possible to sync hidden variables. For this purpose, you have to go to the settings of hm-rega. At the Sync tab you will find Invisible variables when Variables is checked.

I want to execute my own scripts on the CCU via ioBroker. Is this possible?

Since version 2.3.0 it is possible to execute your own scripts on the CCU by using the sendTo command. E.g., getting the uptime of your CCU by the following script:

My CCU webinterface has a different port than the standard http/https protocols, thus no connection is established. How can I configure the adapter to use a custom port for the webinterface?

Until now, this is an edge case and thus no configuration in the Admin GUI is possible. This has been decided because it would confuse 10,000 users to help one user. However, the port can still be changed via the cli, using the following command:

iob set hm-rega.0 --webinterfacePort 8765

To use default port settings again, either set 443/80 according to your protocol, or set 0 for automatic selection.

const upTimeScript = `
    string stderr;
    string stdout;
    system.Exec("cat /proc/uptime | awk '// { printf $1/3600 }'", &stdout, &stderr);

sendTo('hm-rega.0', upTimeScript, res => {
    log(JSON.stringify(res), 'info');

My Rega API is running at another port than 8181 (HTTPS: 48181), can I use the adapter anyway?

If your Rega API is running at a non-default port (which should only happen in edge cases), we assume that you are familiar with the ioBroker CLI. You can change the port via iob set hm-rega.<instance> --homematicPort <port>
