Important — Setup Order

Do not plug in the Cellular Gateway until after you've created an account on iMonnit.com and added your cellular gateway and wireless sensors to the account. Once plugged in and all three status lights turn green, the network is ready to bring sensors online.

1. Creating a Monnit Account and Setting Up a Sensor Network

1. Navigate to imonnit.com and click "Get Started Here" to create an account (skip this step if you already have one).
2. Follow the on-screen prompts to enter your account and contact information.
3. Create your first sensor network by entering a name for it.
4. Add your MonnitLink™ gateway's ID/Code information and click "Assign Gateway."
5. Add your first Monnit wireless sensor's ID/Code and click "Assign Sensor," then name the sensor and select its use type from the dropdown (the system suggests settings based on this).
6. Set up notifications for the newly added sensor — choose from suggested pre-configured notifications, or create a custom one (custom notifications become reusable for any similarly-typed sensors added later).
7. On the confirmation screen, assign any additional sensors or click "Done" to begin using the system.

2. Using the MonnitLink CGW2 Cellular Gateway

Ethernet Gateway Status Lights

Note: The gateway resets itself after receiving new configuration from the server — LED1 starts red and cycles until all 3 LEDs are green. During a software upgrade, LEDs scroll red; after a successful upgrade they flash green and the gateway restarts.

Control Button

• Short press (while lights are all green): forces immediate communication to the server, exchanging all stored sensor data.
• Press and hold until all lights go red: resets the gateway to factory settings (60-minute heartbeat). You'll need to log back into the online system to reconfigure it.

If the gateway powers up and lights don't turn green: wait a few minutes, then power-cycle the device. If it still doesn't connect, try a factory reset; if that fails, contact Monnit customer support.

Configuring the Cellular Gateway

The gateway collects data from all sensors in range and batch-delivers messages to the online system at a configurable heartbeat (default: every 60 minutes). Access settings via "View Gateways" in the Overview page, click the gateway, then the "Edit" tab.

3. Using Your Monnit Wireless Sensors

Keep sensors at least 3ft. from the Ethernet Gateway. Peel back the battery slot's sticker cover and slide in the coin cell battery observing polarity — the sensor powers on within 10-20 seconds. Configuration changes made in the software are transmitted to the sensor on its next heartbeat; for an immediate update, power-cycle the sensor (remove and reinsert the battery).

Warning: sensors ship with a 10-minute heartbeat. Unless using the AA battery option, set the heartbeat to no faster than one hour to preserve battery life.

Manual Sensor Reset: use a paper clip to push the battery out through the small hole in the top of the sensor, change the heartbeat setting in the online system, then re-insert the battery.

4. Using the iMonnit Online System

Menu System

• Overview — all sensors and their last readings
• Notifications — manage notifications and view sent history
• Manage — manage networks, sensors, and gateways
• Reports — printable account/network reports
• Sensor Maps — visual sensor placement tracking
• Support — help resources

Sensor status indicators: checking in within safe parameters, exceeded a threshold/triggered event, not checked in (inactivity alert sent), no readings since shipping, or inactive (no readings recorded).

Sensor Details View Tabs

Chart (graphical data view), Notifications, History (text data log), Export (.csv archive), Edit (settings), and Calibrate (available for select sensor types, e.g. temperature, for accuracy correction).

Configuring Sensor Settings

Click a sensor row to expand the details view, then the "Edit" tab to change primary configuration. Hover the question-mark icons for setting explanations. Click "Save" to apply — changes download to the sensor on its next heartbeat, and the configuration can't be re-edited until that download completes.

Notifications

Four notification classes:

• Application — sensor-specific triggers (e.g. water present, temp above 70°F)
• Inactivity — alerts when sensors stop communicating (recommended for every sensor, or you won't be notified of a dead sensor)
• Low battery — alert at a defined battery percentage threshold
• Advanced Notifications — rules comparing historical vs. current data points

Each notification specifies People to Notify (auto-suggested from network users, or added via "Add Recipient"), Notification Parameters (name, custom message, trigger conditions), and Assigned Devices (which sensors trigger it — application-specific notifications only apply to matching sensor types).

Exporting Sensor Data

Select a date range and scope (single sensor, network, or entire account) then click "Export Data" to download a .csv file (first 2,500 records in the range). Alternatively, use "Configure data push" to forward incoming sensor data to a third-party service in real time via an HTTP GET request with URL-encoded parameters.

Calibrating Sensor Data

For sensors that support it (e.g. temperature), the "Calibrate" tab lets you replace the last reading with a known-accurate value — all future readings are adjusted based on the new calibration.

Managing Sensor Networks

The "Manage" page lets you edit network details, create new networks, add/remove devices, move devices between networks, and clear a sensor's history (irreversible — export first if you want a record).

Regulatory & Support

Complies with FCC Part 15, Class B. RF exposure: maintain 20cm+ separation between the antenna and persons during operation; the antenna must not be co-located with any other antenna or transmitter. Additional documentation and video tutorials: monnit.com/support.
