Someone switched a relay by hand, at the relay itself or on its relay board, rather than from the controller. Nothing is wrong; while the relay is held by hand, automatic control of that output is paused.

Changed in an upcoming firmware update. Earlier firmware named only Local Override, and the alarm stayed active after the relay returned to Auto. The new wording and self-clearing are built and simulator-tested; not yet tested on hardware.
A Hand/Off/Auto change was made away from the controller — on a Wireless Relay Strip or Wireless Relay Expander, or on a Legacy Relay Device 6. The controller adopts the new state and raises this alarm so the change is visible. The detail says when control returns:
| Shown as | Detail | Then |
|---|---|---|
| Relay Manual On - 5 min | Switched on by hand. It runs for 5 min, then control returns to Auto. | The relay runs for its set time, then returns to Auto |
| Relay Manual Off | Switched off by hand. It stays off until it is set back to Auto. | The relay stays off until someone sets it back to Auto |
The alarm is raised only once the controller has actually adopted the manual state.
On a Wireless Relay Strip, a press that ends a Hand On, or a Hand On started from an outlet that was held off, returns the outlet to the setting it had before — see The buttons on a Wireless Relay Strip.
Pauses its control mode’s command to that relay while it is held by hand, and clears the alarm when the relay is back under Auto.
A mode can also be set to watch for a local override and push back — see Local override.
