Kisi shows the door as open at all times
If you are seeing your doors as "Open" at all times, this can happen if the contact sensor for the specific door is enabled even though you do not have a contact sensor physically installed. If this is the case, the door will report as open at all times, even when it is not.
To resolve this, navigate to the Kisi Web Dashboard, go to the Hardware > Controllers and click on the controller the door in question is associated to. Check "Contact Sensors" to see if any are enabled incorrectly, and disable them if needed.
Kisi shows the door as open when it is closed, and closed when it is open.
If Kisi always indicates the door's state as the opposite of its physical state, this could mean the contact sensor is wired incorrectly, or the wrong configuration of contact sensor was used. Contact sensors may come with normally closed (NC) and normally open (NO) switches, and some contact sensors for sale may even be labeled incorrectly.
The Kisi Controller's sensor input channels receive simple signals based on circuit state. The corresponding circuit and door state is shown in the table below. If your Kisi Controller has an LED indicator for its sensor inputs, this is also listed here.
| Circuit state | Blue LED | Door status |
| OPEN | Unlit | OPEN |
| CLOSED | Lit | CLOSED |
Not all Kisi Controller models have LED indicators on input channels. This can vary between minor hardware revisions.
You may test your contact sensors using a multimeter on the continuity setting.
- Disconnect the sensor inputs from your Kisi Controller
- Set your multimeter to the continuity setting.
- Touch your probes to the wire ends of your contact sensor circuit.
- Test with the door closed. If installed correctly, the multimeter should detect continuity.
- Test with the door open - If installed correctly, the multimeter should not detect continuity.
