WebComm-Calendar-Sync
Docker app from 2CrAzY's Repository
Overview
WebComm Calendar Sync automatically reads WebComm duty schedules, detects changes, synchronizes work shifts to ICS, CalDAV or Google Calendar, can send optional Telegram notifications, and can optionally integrate with Alarm-HUB. Chromium and persistent configuration are included in the container.
Requirements
WebComm credentials are required for schedule synchronization. Optional integrations such as Alarm-HUB, Telegram, CalDAV and Google Calendar can be left unconfigured. The built-in HTTPS mode uses a locally generated certificate; configure TLS SAN values for the address used to open the WebUI.
