Gateway Overview
What HPzenAi gateways do, model differences, and when to use each.
What is an HPzenAi IoT Gateway?
The HPzenAi IoT Gateway is the central hub of your smart monitoring network. It bridges your field devices — water meters, level sensors, relay controllers, and motor starters — to the HPzenAi cloud platform and mobile app. Using RS485 Modbus RTU on the wired side and Wi-Fi, Bluetooth, SIM, or RF on the cloud side, the gateway continuously collects readings, forwards them securely to the HPzenAi platform, and relays remote commands back to connected devices.
Highlights
- Multi-Protocol Communication: RS485 Modbus RTU, 2.4 GHz Wi-Fi, BLE 5.0, nano-SIM cellular, and 433/915 MHz RF in a single device
- Up to 32 Field Devices: Support up to 32 RS485 devices per bus — water meters, level sensors, relay controllers, and more
- DIN Rail Mounted, IP54: Standard 35 mm DIN rail mount, compact enclosure rated IP54 for panel and outdoor cabinet installations
- Real-Time Alerts & Cloud Sync: Live data on the HPzenAi app, push notifications, and 24-hour local data buffering during connectivity outages
Product Description
HPzenAi gateways are industrial IoT edge devices designed for reliable, long-term deployment in utility, agricultural, and building automation environments. Each gateway combines a wired RS485 Modbus RTU bus interface with one or more wireless uplinks to the HPzenAi cloud, providing secure encrypted data transmission and remote device management.

Applications & Use Cases
HPzenAi gateways are deployed wherever field devices must be monitored and controlled remotely. Choose the gateway model based on the available uplink infrastructure at your site.
| Application | Description |
|---|---|
| Smart Water Metering | Aggregate readings from multiple RS485 water meters in a building or campus and deliver data to the HPzenAi dashboard for billing and consumption analysis |
| Tank Level Monitoring | Monitor overhead tanks, sumps, and underground reservoirs using level sensors connected over the RS485 bus, with automatic pump control via relay outputs |
| Remote Agricultural Sites | Use GW-1 or GW-2 with SIM fallback for farms and irrigation networks where broadband is unavailable — data is always delivered via cellular |
| Industrial Facilities | DIN rail installation inside control panels for process water, HVAC, and building services metering in factories and warehouses |
| Apartment & Housing Estates | Sub-metering networks with up to 32 meters per gateway — ideal for residential complexes and managed properties |
| Government & Utility | Robust utility-grade data collection from distribution points, pumping stations, and municipality supply connections |
| Borewell & Groundwater | Level sensors on deep borewells connected to the gateway enable remote depth monitoring and pump dry-run protection |
| RF Mesh for Open Areas | GW-1/GW-3 with 433/915 MHz RF bridges wireless field devices over distances up to 1.5 km, avoiding expensive cable trenching |
Available Models
