ScenarioBuilding Energy Retrofit
LoRaWAN sensors mount on the wall, one gateway connects existing Modbus and BACnet equipment, and the data goes to an open-source dashboard or your own platform.
Home & Building Automation
See building energy use and bring existing equipment under one control layer
Sensor and meter data flow into an edge gateway where one point model connects OPC UA, Modbus and BACnet equipment; applications run locally or connect to your platform.
Multi-Protocol
Four protocols in one point model; existing controllers and meters stay
Wireless, No Cabling
Sensors mount on the wall; legacy RS485 meters join via S2100
Local Prediction
Setpoints predicted from the building's own history, every write read back

ScenarioBuilding Energy Management
Connect existing and new devices by floor and system. Start with energy monitoring, then expand to control; view electricity, water, and HVAC data together.
Reference designHVAC Automation Control
Bring HVAC controller points and an energy meter into one point model, predict setpoints from the building's own history, and write them back only after a readback from the field matches — with rollback and alarms when it does not.

Reference designMulti-Protocol Industrial Gateway
Bring OPC UA, Modbus, BACnet/IP, and MQTT devices into one point model, then read and control them through one MQTT interface.
Hardware
Wireless sensors and LoRaWAN loggers report to a LoRaWAN gateway, wired equipment connects to a reComputer R gateway host, and all data lands on one data server.

Use Case
Field devices → terminals → gateways → data server → SCADA
Wired devices connect over RS-485 to a LoRaWAN logger, a 4G logger or the gateway host, and wireless sensors go straight to the LoRaWAN gateway. All data lands on one data server (cloud, or an on-premises reComputer running Home Assistant), read by the SCADA dashboard on a reTerminal touch terminal. The tabs follow the diagram's blocks.
Core Advantages
- Wired and wireless in one server
- LoRaWAN, 4G or Ethernet backhaul
- Cloud or on-premises

Wireless sensors to the gateway, weather station on RS-485
SenseCAP S21xx wireless sensors cover indoor points such as temperature, humidity, CO₂ and light, and reach the LoRaWAN gateway directly. The S700 weather station covers outdoor points; its RS-485 model connects through a field acquisition terminal.
Core Advantages
- Temperature, humidity and air quality
- 7-in-1 outdoor weather
- LoRaWAN, no cabling

Loggers for scattered points, gateway host for wired runs
The S2100 turns RS-485 meters into LoRaWAN nodes. Sensor Hub 4G reports directly over 4G with no gateway on site. Centrally wired equipment connects to a reComputer R series gateway host; the R1225 has LoRaWAN built in and can also act as the LoRaWAN gateway.
Core Advantages
- RS-485 to LoRaWAN
- Direct 4G uplink
- Node-RED on the gateway host

LoRaWAN gateway for wireless data, local server runs Home Assistant
SenseCAP M2 receives data from wireless sensors and LoRaWAN loggers; with an R1225 gateway host it is optional. The data server runs in the cloud or on an on-premises reComputer R1100 running Home Assistant.
Core Advantages
- Indoor LoRaWAN coverage
- Home Assistant runs locally

FAQ
Energy and environmental monitoring, HVAC setpoint control, and connection and alerting for field devices such as meters and sensors.
Controllers and meters that speak Modbus, BACnet or OPC UA stay in place, and the gateway handles collection and integration.
The gateway supports four protocols: OPC UA, Modbus TCP, Modbus RTU and BACnet/IP. In the field, use LoRaWAN sensors, and connect RS485 meters through the S2100.
Yes. Dashboards and control logic run on the gateway, with an optional link to a customer platform. This is not a safety-certified control system and does not suit applications that require certified safety control.
Seeed can evaluate enclosure, branding, packaging and interface changes as a customization project.
