Operation
| Property | Field | Values | Default | Bindable | Notes |
|---|---|---|---|---|---|
| Command | command | On / off | Off | Yes | Shown when Feedback is Single (open) or Double (open + closed). Maintained command signal (run / open request; not a pulse command). While it differs from the feedback: transition (half fill); when the travel time runs out: discrepancy (alarm color + badge) |
| Travel time (s) | travelTime | Number | 30 | — | If the command is not fulfilled within this time: discrepancy. Empty: motor / pump 10 s, valve 30 s |
