As system integrators and building automation providers seek localized, vendor-agnostic IoT solutions, ZigBee2MQTT emerges as the backbone for scalable commercial deployments. OWON Technology – an ISO 9001:2015 certified IoT ODM with 30+ years in embedded systems – delivers enterprise-grade devices designed for seamless MQTT integration, eliminating cloud dependency while ensuring interoperability with Home Assistant, OpenHAB, and proprietary BMS platforms.
| Device | Core Features | B2B Use Cases | Integration |
| CB432 | 63A relay + energy metering DIN-rail | Load shedding, peak shaving | Modbus RTU over MQTT |
| PC321-Z-TY | 3-phase clamp meter (500A) | Solar/EV fleet monitoring | JSON payload via ZigBee2MQTT |
| PCT504-Z | 4-pipe FCU control (100-240VAC) | Hotel HVAC automation | Tuya-API alternative |
Unlike consumer-grade alternatives, OWON’s ZigBee 3.0 certified devices offer:
- Device-level API access: Direct MQTT cluster control for custom logic (e.g., trigger HVAC based on occupancy data from PIR313-Z)
- Zero-cloud operation: Critical for utilities and healthcare projects with data sovereignty requirements
- OEM/ODM flexibility: From firmware customization (e.g., Modbus translation) to white-label DIN-rail housings
