Control power to third-party devices
This is an experimental feature that has not yet been fully tested. We recommend contacting our support team to discuss your setup before wiring anything.
The Kisi Controller Pro 2 can switch power to a third-party device in the same way it controls a door lock. When a door is unlocked, the controller changes the state of the relay output the device is wired to. By configuring a door for the device, an unlock can be used to switch the device's power.
Because most third-party devices use AC power or draw more power than the controller's relays support, you switch the device with an external power switch — such as a smart plug or an IoT power relay — placed between the controller and the device's power source. The controller provides the unlock signal, and the external switch performs the actual power switching. You control how long the device stays powered after an unlock by creating a door for the device and setting its unlock duration to the time you need the device to remain powered.
The Kisi Controller Pro 2 does not support alternating current (AC) wiring. Never run an electrical load through the controller that exceeds its documented relay limits. Doing so can damage or permanently destroy the controller, and any load outside the documented specifications voids the warranty. If you are unsure whether your device is within the supported limits, contact your installer before wiring anything. This is why an external power switch is used — it handles the device's load so the controller only provides the low-power unlock signal.
Power the device through an external power switch
- Select an external power switch that matches the device's power requirements and can be controlled via a relay. We suggest the Controllable Four Outlet Power Relay Module, which accepts a single control signal to switch its outlets
- Follow the switch manufacturer's instructions to determine whether its control input expects a powered signal (wet contact) or a contact closure (dry contact). For the suggested relay module, set the controller jumper to the appropriate 12VDC or 24VDC wet position, connect controller GND to the module's control negative terminal, and connect controller NO to its control positive terminal. For a dry-contact input, set the jumper to dry and connect COM and NO as specified by the switch manufacturer
- Connect the external power switch to the third-party device and a power source
- Create a door for the device. Then assign the door to the selected controller relay and set Duration to how long the device should stay powered after an unlock
- Test that unlocking the door triggers the external power switch and powers the device
If the external power switch is controlled directly by the controller's relay signal — as with the suggested relay module — no custom integration is needed. A custom integration layer is required when the switch cannot be driven by the controller's relay signal and must instead be triggered another way, such as over the network for certain smart plugs. Please contact our support team about the possibility of implementing an integration layer for your setup.
Limitations
The controller can only switch power. It cannot control what a device does once it receives power. Many devices, such as projectors or screens, do not turn on automatically when powered and require a physical button press.
