ESUMEI / Industrial Monitoring Platform
Field Devices → Edge → Cloud
Industrial data, from field to cloud.
ESUMEI G3 connects to RS-485/Modbus field devices. ESUMEI OS acquires and buffers the data at the edge. ESUMEI Cloud makes it available anywhere — or build your own path with the Python SDK.

Public competitor pricing shown for comparison and may vary by configuration, region and supplier. "Not listed" means the manufacturer's published documentation does not clearly establish the value — it is not a claim that the capability is absent.
Built for mixed-generation networks
ESUMEI G3 uses 4G LTE Cat-1bis for primary connectivity with 2G fallback, helping remote deployments remain reachable at sites where LTE is unavailable but a 2G network is still in service.
This can be particularly useful for industrial and utility assets deployed across regions where multiple generations of mobile infrastructure remain operational.
04Edge Software
ESUMEI OS
The edge software running on every ESUMEI G3 — acquisition, buffering, and connectivity, handled at the site.
01
Poll
Reads compatible RS-485/Modbus devices using meter templates.
02
Normalize
Converts readings into a standardized electrical data model.
03
Buffer
Resilient local storage — store-and-forward through outages.
04
Connect
Manages cellular connectivity, outbound-only and TLS-encrypted.
05
Forward
Sends data to configured destinations over MQTT or HTTPS.
Backfill After Outages
Buffered readings drain in order once connectivity returns.
Validated Before Applying
Config changes are checked before they take effect.
Remote Configuration
Supported meters and connectivity, configured remotely where supported.
05Managed Cloud Service
ESUMEI Cloud
The managed service that receives, organizes, and visualizes data from deployed ESUMEI controllers.
ESUMEI Cloud
Deployed controllers reporting into one managed service — organization shown abstractly, not real customer data.
Consume & Visualize
Remote data access and visualization for deployed controllers.
Organize & Provision
Controller and device organization, provisioning, and asset identification.
Alerts & Updates
Alerts, notifications, and managed update coordination.
06Feeder Monitoring
