Output names and control topics
- Relay and digital-output names are required and must be fewer than 32 UTF-8 bytes.
- A control topic is required even when remote control is currently disabled.
- Topics may contain at most 128 UTF-8 bytes and cannot contain spaces, control characters, a leading or trailing slash, or an empty level such as
//. - The firmware matches actuator commands to an exact topic, so
+and#wildcards are not accepted. - Local output controls are disabled while the section has unsaved changes. Each live switching action opens a confirmation dialog and changes the connected equipment immediately after confirmation.
