Device setting (from the KMTronic Howto)

The default IP address of the device is If your LAN IP mask is different, you need one time access to network 192.168.1.x to change default setting of KMTronic.

Open a browser and type

The default user is admin with password admin.

In “Configuration” menu you can change default IP Address, Gateway and HTTP Port.

For the integration with Control4, the device must have a fixed IP address. Please, set it on the device or in your DHCP server setting.

In “Authorization Configuration” you can change username name and password for device authentication. They will be required during the Driver configuration, so write them down.

In the relay control interface you can test your device relays.


Driver installation

Install the driver in your Control4 project using the composer (as any other driver) and set the folllowing properties:

Debug: in normal operating conditions is better to set it to “Off”

KMTronic IP: device IP you set in the previous step.

KMTronic Port: device HTTP Port if you changed it.

KMTronic User & KMTronic Password: the one you use to access to the device from a browser (web interface).

Polling: Set it to “On” only if you plan to change the state of the relay from the native KMTronic web interface, otherwise it is not necessary.

Polling seconds: select the frequency you want to update Control4 about the change coming from the KMTronic web interface.

the license is bound to such number. The first license dealers get for free is limited to 2 boards.

License code: copy & paste here the license code obtained during the license buying process.



For each relay, you will find a KMT Relay connection that allows to connect it to the proper device (eg: relay, fan, pump, gate, blind, …)


You simply have to create new connections.

The following incoming commands from other drivers are supported: OPEN, CLOSE, TOGGLE & TRIGGER.
