Signal Library
Store, browse and reuse captured signals on the device and in the app.
Signal Library
Captured signals can be saved to Echo's on-device library for later inspection, replay, or arming to the button. The library lives in Echo's built-in storage, there is no memory card.
The workflow
After a capture decodes (see Sub-GHz Capture), save it to the library from the app with a name of your choosing. Both fixed-code and rolling-code captures can be saved, saving never depends on whether the signal can later be replayed.
Storage
| Capacity | 10 MB of on-device capture storage |
| Shared with | Settings and license also live in the same on-device storage |
10 MB is enough room for a large library of signals, fixed-code and rolling-code alike, well beyond what a single project or vehicle typically needs.
Saved rolling-code signals are kept so you can inspect and identify them, but Echo refuses to replay them, or arm them to the button, or send them from a rule. Only fixed-code signals can be replayed. See Rolling-code.
