Connect our gateway to your RS485 bus and view all your consumption metrics in your cloud dashboard every 15 minutes—no access badges required, no need to travel, even at busy sites.
An Eziwan gateway natively supports Modbus RTU RS485, M-Bus EN 13757, TIC Linky, and pulse inputs—without requiring any additional modules or licenses per protocol.
Class 0.5S three-phase power analyzer. Modbus registers: 0x0000 (L1 voltage), 0x0006 (L1 current), 0x0034 (total active power), 0x0156 (total active energy). Address range 1–247, baud rate 9600/19200.
PowerLogic PM5xxx Series. Modbus RFC registers: 2999 (imported active energy), 3009 (reactive energy), 3517 (maximum power demand). Optional Modbus TCP support.
ABB B-series meters. Registers: 0x5000 (imported active energy in kWh, 32-bit float), 0x5002 (reactive energy in kvarh), 0x5008 (instantaneous active power in W). Class 1 and Class 2.
Socomec Multimeter Analyzers. Registers: 50536 (total imported kWh), 50537 (total exported kWh), 50560 (kVA). Socomec Jbus/Modbus RTU protocol, 2400–38400 baud.
Legrand modular meters for low-voltage distribution panels. Modbus address configurable via DIP switch. Registers 0x0048 (active energy), 0x004A (reactive energy). Format: 16-bit signed ×10 Wh.
Carlo Gavazzi analyzers. Registers: 0x0000 (V L1-N), 0x0012 (Total Power W, 32b), 0x0040 (Imported kWh, 32b). RS485 baud rate up to 19,200 baud, configurable parity (N/E/O).
A typical installation on a distribution panel with 8 to 12 pre-wired Modbus RTU meters takes less than 2 hours.
Beyond simply reading meter readings, our platform analyzes, alerts, and reports—to turn your meter data into concrete actions.
Choose the time resolution that best suits your needs: 15 minutes for detecting consumption spikes, 30 minutes for tracking the ENEDIS load curve, and 1 hour for OPERAT compliance. Each reading is time-stamped and stored with redundancy.
Set thresholds for any measured parameter: active power in kW (contract overage alert), daily energy consumption in kWh (excess consumption alert), water flow rate in m³/h (leak alert), temperature differential (refrigeration capacity alert). Notifications via email, SMS, or CMMS webhook.
Schedule the automatic sending of PDF or Excel reports: consumption by cost department, monthly trends, year-over-year comparisons, and energy intensity metrics (kWh/m², kWh/metric ton produced). Ready for the ISO 50001 energy management standard audit.
Automatic detection algorithms: abnormal nighttime consumption (water or gas meter active outside of business hours), gradual increase in consumption (+15% compared to the 30-day moving average), leak detected by a non-zero baseline flow rate on weekends.
Native formats for Dalkia Energy Management, eSight Energy, Schneider Power Advisor, and Siemens Navigator. OPERAT (ADEME) export for Tertiary Sector Decree reporting. Native connector to EcoStruxure Resource Advisor and EnergyCAP.
The Eziwan REST API (OpenAPI 3.0) exposes your data in real time: GET /meters/{id}/readings?from=&to=&interval=, POST /alerts, GET /sites/{id}/report. Native Power BI connectors, Grafana data source plugin, Tableau Web Data Connector. OAuth2 / Bearer authentication.
Each sector has its own specific needs: production meters, tenant sub-metering, in-store refrigerators, or community gyms—Eziwan covers every business scenario.
Sub-metering for workshops, production lines, compressors, furnaces, and cooling towers. Break down energy consumption by production cell to manage your energy costs per metric ton produced. SAP/Odoo ERP integration via API.
Utility cost allocation for tenants in condominiums, multi-tenant offices, and shopping centers. Accurately bill each occupant based on their actual usage, which is automatically recorded each month.
Multi-site remote meter reading, retail locations, refrigerated display cases, HVAC. Centralize energy consumption data from 10 to 500 stores in a single dashboard. Immediately detect anomalies in refrigeration energy consumption.
Schools, gyms, swimming pools, municipal buildings, public housing offices. Optimize your local energy budget, plan for expenses, and track your energy reduction goals under the Tertiary Sector Decree, municipality by municipality.
Le Decree No. 2019-771 of July 23, 2019 (known as the “Tertiary Decree” or “Tertiary Eco-Energy Program”) requires all tertiary-use buildings larger than 1 000 m² to reduce their final energy consumption by 40% by 2030, 50% by 2040, and 60% by 2050 compared to 2010.
Every year before the September 30, taxpayers must report their annual energy consumption (electricity, gas, cooling, heating) on the platform OPERAT (Observatory for Energy Performance, Renovation, and Actions in the Service Sector), managed by ADEME.
In the event of failure to report or noncompliance: up to a €7,500 fine per year for property owners, with reporting in CSR statements. Eziwan’s automatic remote meter reading system guarantees reliable and traceable data that can be exported directly in OPERAT format.
