Linked Switches

Linked Switches keeps 2 to 10 on/off devices in sync, so any switch or Homey action changes them all together. You can optionally mark one device as Primary. That device is controlled first, and the rest follow with a small stagger to keep your Zigbee network calm. Switch Master is for scene-style control: use 1 master and 2 to 9 slave devices. The master can override the slaves, the slaves keep their own control, and the master syncs back when all slaves agree. Switch Master can include devices that already belong to a Linked Switch group, but only one member per group to avoid redundant commands. A shared sync log in the app settings helps you diagnose failed writes and offline devices.

What’s new

Version 1.1.5 — Added a global Boot Sync Policy on the app's Configure page. By default, when the app starts, a Linked Switch group now writes its last saved ON/OFF state to the devices that differ from it; choose "Any ON wins" to keep the previous behaviour. A health-check re-subscription no longer changes any device or the group state, so a failed OFF command can no longer turn the whole group back ON. Fixed a debounce race where a fast ON/OFF from the same device could re-deliver the older value. Removed the "Group is waiting for an offline device" Flow condition, so Flows that use it must be updated; "Group is fully synced" covers that case. The remaining hard-coded texts are now translated. The Flow cards ("A device failed to sync", "Group is fully synced", "Force resync") are now deprecated: they are hidden when creating new Flows, and existing Flows keep working. Removed the debug logging toggles (app-wide and per group): the logs were only readable from the developer console, not from an installed app.
