HMScriptEditor is a very simple editor and runner for HomeMatic ("Rega") scripts.
The editor features syntax highlighting (but no code completion). Scripts can be directly started from within the editor. Run and test them on any preconfiguried CCU.
Thanks to the support for macOS services, HomeMatic scripts can be directly run from any text field. For example you can open scripts from within the HomeMatic forum website, or even run them straight away.
