About

Matter Time Sync is a Marketplace integration that sets the time and timezone on Matter devices. It talks to a Matter Server over its WebSocket URL and works locally. The integration adds a button for syncing time, plus actions to sync one device, sync all devices and refresh the device list. Settings cover the timezone, a comma-separated device filter with a choice of filter target, and an option to limit it to devices that support Time Sync. Automatic synchronization can be turned on with a set interval. It is added as a custom repository in the Marketplace and configured in the UI.
