Signal License expands the Remote's multi-device coordination by adding frequency or grouping capability shown in accepted gameplay. Use the Remote to link switchable tools, separate groups when the current interface allows it, and test each group before running the whole factory. Exact channel counts, per-channel capacity, and the maximum number of devices remain 待确认.
Treat Signal as a Remote-control extension
The accepted sources do not establish a separate handheld Signal tool with its own independent workflow. Instead, gameplay connects Signal License to additional Remote frequency or group control for several switchable devices. Begin with the Remote linking process, then use the current interface to identify any extra group or frequency option provided by the license.
Create one functional group
Link a small set of devices that should change state together, such as fans serving one transport section. Toggle the group while no products are moving and confirm that every intended device responds while unrelated tools remain unchanged. Fix missed or accidental links before building a second group.
Separate factory stages logically
Use different available groups for devices that should not run at the same moment, such as a collection stage and a downstream release stage. The purpose is coordination, not simply placing every fan under one command. Keep each stage visible and test the handoff with a small batch so that timing problems are obvious.
Do not publish video-specific limits
One video describes an extra frequency and device capacity, but the official site and store page do not publish those numbers. Captions and interface versions can also differ, which makes a precise limit unsafe to generalize. Read the current UI for available groups and capacity, and mark any number not displayed there as 待确认.
Troubleshoot the Remote before Signal
If a grouped device does not respond, verify that it is switchable, manually functional, and correctly linked with the Remote. An apparent Signal problem can be a missed link or a tool left in an unexpected state. Only investigate group or frequency behavior after each device works correctly in a simple Remote test.
