LoRaWAN Solar Powered Gateway + DLMS-to-LoRaWAN AMRs

DeviceBoard enables a complete, scalable, cloud-based utility management solution by integrating DLMS smart meters, DLMS-to-LoRaWAN AMR modules, and a LoRaWAN Solar Powered Gateway that forwards aggregated utility data directly to DeviceBoard Cloud.

This architecture supports Smart Electricity, Smart Water, Smart Gas, and Renewable Energy monitoring across residential, commercial, industrial, and smart city deployments.

DeviceBoard’s utility management ecosystem consists of:

✔ DLMS-to-LoRaWAN AMR Modules
Attached to DLMS meters to convert meter readings into LoRaWAN uplinks.

✔ LoRaWAN Solar Powered Gateway
Collects LoRaWAN AMR packets from multiple meters and forwards them to DeviceBoard Cloud.
(No network servers or wired infrastructure required.)

✔ DeviceBoard Cloud
Central platform for meter data analytics, billing automation, anomaly detection, and reporting.

DLMS Meter → DLMS-to-LoRaWAN AMR → LoRaWAN Solar Gateway → DeviceBoard Cloud

LoRaWAN Solar Powered Gateway Responsibilities:

• Collect uplinks from multiple DLMS AMRs within a coverage zone
• Act as a private LoRaWAN Network Server at the edge
• Manage LoRaWAN join-requests & session keys
• Forward decrypted and formatted payloads directly to DeviceBoard via MQTT/HTTPS
• Operate entirely on solar power (no external wiring or grid power required)

This makes it ideal for:

• Rural utility metering
• Urban outdoor deployments
• Large residential complexes
• Industrial energy measurement farms

Each AMR device:

• Reads DLMS registers from a standard smart energy meter
• Converts values to compact LoRaWAN messages
• Sends periodic or event-based uplinks to the solar gateway
• Supports OTA updates and over-the-air configuration
• Works with multiple meter types (1P/3P, whole current, CT-operated, etc.)

The gateway communicates directly with DeviceBoard Cloud over secure protocols:

• MQTT over TLS
• HTTPS/REST

Key Functions:

• LoRaWAN packet reception and decoding
• Automatic AMR device authentication
• Meter payload parsing
• Forwarding structured JSON telemetry to DeviceBoard
• Uplink timestamping and deduplication
• Forward error correction support

Benefits:

• No wired internet required
• Zero power infrastructure (solar powered)
• Supports hundreds of AMRs in a single cluster
• Very low maintenance cost

Common workflows include:

6.1 Overload Management

IF load > 90% rating THEN alert substation operator

6.2 Low Solar Output Condition

IF solar_output < expected_by_AI THEN trigger performance alert

6.3 Water Leak Workflow

IF water_usage continues at night for > 60 min THEN raise leak alert

6.4 Peak Hour Control

IF usage > tariff_slab_threshold THEN recommendation to reduce load

6.5 Tamper Alert Workflow

IF tamper_event THEN create high-severity alarm + notify engineer

DeviceBoard builds Digital Twins for:

• Meters
• Solar inverters
• Transformers
• Water pumps
• Gas distribution nodes
• Aggregation zones

Each twin includes:

• AI anomaly insights

DeviceBoard generates:

• Daily consumption reports
• Monthly billing reports
• Tamper event logs
• Solar performance reports
• Leak audit reports
• Feeder analysis
• Net metering summaries

Reports can be scheduled or exported to PDF/Excel.
