Both first-time setup and normal sign-in begin on the gateway's local hotspot. Keep the hotspot password from the gateway label nearby. For a new gateway, also prepare your Wi-Fi or cellular details.
1. Join the setup hotspot
Power on the gateway
Fit both antennas, connect the approved DC supply, and wait about one minute for the gateway to start.
Find the gateway network
Open the Wi-Fi list on your laptop or mobile device and select Protonest-Master-XXXX, where
XXXXis the last four characters of the MAC address.Enter the hotspot password
Use the password printed on the gateway label. If several gateways are nearby, match the hotspot name to the device label.
2. Open the web console
Open the local address
In a browser, go to http://192.168.4.1.
Follow the page shown by the gateway
A new, uncommissioned gateway opens the onboarding wizard immediately. A gateway that has already been configured opens the sign-in page.
3. New device: complete onboarding
On a new device, the three-step onboarding wizard appears before any sign-in page. The progress indicator in the upper-right shows where you are.
Choose your sign-in details
Enter a new administrator username and password, repeat the password, and select Save and continue.
- Username: 8-31 characters using letters, numbers, dots, underscores, or hyphens.
- Password: 8-63 UTF-8 bytes. The repeated value must match.
Identify the gateway
Enter identifiers that distinguish this gateway in dashboards and MQTT data:
Device ID: gateway-01
Site ID: factory-a
Select Save and continue. You can select Skip and configure these values later under Settings > Device identity.
Device ID and Site ID are required when this step is saved and may each contain up to 31 UTF-8 bytes.
Connect to a network
Select Wi-Fi, enter the case-sensitive network name and password, then select Save and finish. Use a 2.4 GHz network.
Use Back to return to the previous step. Selecting Skip leaves the current step for later; you can change identity under Settings and connectivity under Network. After Save and finish, the gateway opens Overview.
4. Configured device: sign in
If the gateway has already completed onboarding, it asks for the saved administrator credentials.
Enter the administrator credentials
Enter the username and password created during onboarding or last updated under Settings.
Sign in
Select Sign in. The gateway opens Overview after authentication succeeds.
5. Verify the Overview dashboard
Overview opens after onboarding finishes or after a successful sign-in.
Check connectivity
In Network, confirm that Connection shows the gateway is connected.
Check live readings
Confirm that the available sensor and I/O values update.
Review system health
Check Power and Hardware check for warnings. Select Full report if a hardware item is not healthy.
If the gateway is not connected, continue to Troubleshooting.
