When setting up or pairing your AIRMX Pro with our setup page, it’s important to first configure the mock API server. This is necessary because when your device receives the Wi-Fi credentials during the process, it attempts to connect to the internet and sends a device registration request to i.airmx.cn for identification.

Unfortunately, the endpoint is hardcoded in the firmware, and we cannot modify it during the setup process. Therefore, we need to remap this domain name in the upstream device—the router.

Since every router has a different configuration, you can consult your router’s manual or use an open-source DNS tool, or configure a DNAT rule with IPTables. For instance, if you are using a router running on EdgeOS and you have set up the mock server on your Raspberry Pi, which is accessible at 192.168.10.10, you can use the following commands:

set system static-host-mapping host-name i.airmx.cn inet 192.168.10.10
set system static-host-mapping host-name mqtt.airmx.cn inet 192.168.10.10

It’s essential to also configure mqtt.airmx.cn, as this is the domain name for the MQTT broker that the device connects to after completing the registration request. All device status updates and remote controls are handled through this broker. Meanwhile, i.airmx.cn is responsible for processing device registration requests, and the device will periodically sync the time with this endpoint.

I am using Eclipse Mosquitto as the MQTT broker and configuring it for anonymous access since I only run it on my home network. Here’s the configuration file mosquitto.conf that I use to start the service:

listener 1883
allow_anonymous true

Ensure that the network traffic from your AIRMX Pro and your computer is routed through the configured router. You can test the DNS resolution using the ping command:

ping i.airmx.cn

If the configuration is correct, you should see that the resolved IP address is 192.168.10.10 (replace with your local server’s IP). Once confirmed, you can return to the setup page and continue pairing your device.
