From Field Signal to Cloud: Multi-Protocol Acquisition
In Industry 4.0, energy data is only valuable if it is collected accurately and routed securely.
The Wattnow solution adapts to your factory's protocols, then transfers the data to our servers. Here's how our architecture works.
Flexible and Universal Acquisition
The Wattnow device integrates natively with your existing industrial sensors, without requiring new instrumentation.
Universal Concentrator
A single device for all your acquisition needs, eliminating the need for multiple gateways.
Modbus RTU (RS-485)
Direct communication with your slave devices via dedicated UART port. Seamless register reading.
4-20mA Signals
Native support via RClick expansion module. 16-bit analog-to-digital conversion.
PT100 Temperature
Dedicated SPI interface, precise measurement. Compatible with 2, 3, or 4-wire setups.
Energy Measurement (Current Transformers)
Acquisition via non-invasive CTs: from 75 A to 1000 A (up to 4000 A in max config).
| Sensor Type | Interface | Accuracy | Configuration |
|---|---|---|---|
| PT100 | SPI | ±0.1°C (4-wire) | Integrated module |
| 4-20mA | RClick (analog) | 16 bits | Expansion module |
| Modbus RTU | UART / RS-485 | — | Integrated port |
| Current Transformers | CT inputs | Class 1 | 75-1000A (4000A max) |
Cellular Transport via MQTT
Data collected, secured, and routed out of the plant.
Integrated Quectel Cellular Module
The Wattnow analyzer is equipped with a cellular module for transferring measurements to the cloud.
Low-power networks
End-to-end encryption
Industrial IoT protocol
Secure Transmission: Data formatted as JSON published to MQTT topics, with persistence in case of connection loss.
A Single Gateway for the Data Lifecycle
A single device manages the entire data lifecycle
Universal Acquisition
PT100, 4-20mA, Modbus, CTs connect directly
Local Processing
Intelligent conversion by our processor
Secure Transport
Cloud transmission via MQTT / LTE-M / NB-IoT
