feat(webui): add eQ-3 keyserver connectivity status by MichaelN0815 · Pull Request #297 · OpenCCU/OpenCCU-Base

MichaelN0815 · 2026-11-02T13:47:54Z

Summary

Automatically check connectivity to the eQ-3 key server when opening the device teach-in dialog.
Display the connectivity status for Homematic IP RF and Wired.
Add German and English translations for checking, reachable, unreachable, and failed states.

Background

The CGI file is based on the tested OpenCCU WebUI version with existing rootfs adjustments. This may introduce changes beyond the new keyserver check compared with the current OpenCCU-Base version and should be reviewed in the context of the ongoing rootfs patch migration.

Testing

Implementation tested by contributor on OpenCCU. No additional automated or runtime tests performed in this PR preparation.

Refs OpenCCU/OpenCCU#3405

Summary by CodeRabbit

New Features
- Device pairing now shows whether the eQ-3 key server is reachable, unreachable, or could not be checked.
- An unavailable-interface warning appears when a required interface is missing.
Usability
- HmIP local key and serial number entries are converted to uppercase as you type, without moving the cursor.
Bug Fixes
- Leaving the pairing page for the inbox stops install mode only when the relevant interface is present.

Walkthrough

The device pairing page adds interface availability handling and key-server connectivity status. It also converts local HmIP key and serial input to uppercase and stops install mode on inbox navigation only for interfaces reported present.

Changes: Device pairing page

Layer / File(s)	Summary
Interface availability and install-mode cleanup `www/config/cp_add_device.cgi`	The page displays an unavailable-interface row until a section is shown or the interface is detected. Inbox navigation stops BidCos-RF and HmIP-RF install mode only when the corresponding interface is present.
Key-server reachability status `www/config/cp_add_device.cgi`, `www/webui/js/lang/de/translate.lang.js`, `www/webui/js/lang/en/translate.lang.js`	The page checks the configured key-server host and port. It displays translated checking, reachable, unreachable, or failed-check status. Reachable and unreachable results use green and red styling.
Local HmIP input formatting `www/config/cp_add_device.cgi`	The local key and serial inputs convert entered text to uppercase while preserving the cursor position.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Add the dialogNewDevicesUNAVAILWarn translation.

The unavailable-interface row uses ${dialogNewDevicesUNAVAILWarn} at www/config/cp_add_device.cgi:74. No file under www/webui/js/lang defines this key, including the German and English dictionaries. The warning text can therefore be missing when no interface is available. Add the key to both supported language dictionaries, translate.lang.js and translate.lang.extension.js.

Review comment at @www/config/cp_add_device.cgi at line 74: Add the missing dialogNewDevicesUNAVAILWarn translation key to both supported language dictionaries, translate.lang.js and translate.lang.extension.js, so the unavailable-interface warning has text in English and German.

This code originates from the existing OpenCCU rootfs patch 0039-WebUI-Fix-Style-Glitches and is unrelated to the new keyserver connectivity check.

The current PR carries over these existing WebUI adjustments because the CGI file is based on the patched OpenCCU version.

I suggest addressing this finding separately as part of the ongoing rootfs patch migration.

@MichaelN0815 Understood. Given the origin in 0039-WebUI-Fix-Style-Glitches, addressing dialogNewDevicesUNAVAILWarn separately during the rootfs patch migration is reasonable. I will not request that change as part of the keyserver connectivity feature.

The translation concern remains deferred, not confirmed fixed. Would you like me to open a follow-up GitHub issue?

Store the presence result when the fallback check succeeds.

When showSection shows a section after the Interface.isPresent fallback, it does not record that interface as present. OnInbox reads the same body data to decide whether to stop BidCos-RF install mode. Until the interface monitor records the value, teach-in can stay active after Inbox is selected. The monitor normally records the value shortly after page load, so the window is narrow.

Suggested fix

if (result == true) { + jQuery("body").data(section, true); jQuery('#section'+section).show(); jQuery('#sectionUNAVAIL').hide();

@MichaelN0815 Understood. I agree that this concern belongs in a separate follow-up, not in the keyserver connectivity change.

The existing repository guidance requires rootfs patch migrations to preserve behavior 1:1. Any correction should go into the OpenCCU source patch first, then into the migration.

This finding is deferred, not fixed. Would you like me to open a GitHub issue for the follow-up?
