ESP32 OpenMQTTGateway smart plug acts as an BLE MQTT gateway and a power meter

The Theengs Plug ESP32 smart plug runs OpenMQTTGateway firmware to serve as a BLE MQTT gateway and power meter compatible with Home Assistant, Homebridge, OpenHAB, DomoticZ, FHEM, Jeedom, NodeRed, AWS, and any MQTT-compatible IoT or Smart Home system. While the Matter standard should improve interoperability between Smart Home frameworks over time, there are still millions of devices already produced that are not Matter compatible, and the Theengs Plug aims to at least partially address this issue by helping users reduce the number of hubs required and have only one that supports different ecosystems. Theengs Plug hardware specifications: Microcontroller – ESP32 dual-core wireless MCU with 2.4 GHz WiFi and Bluetooth LE connectivity Network Protocol – MQTT Power Supply – 100-120VAC, 60Hz, up to 15A Dimensions – 103 x 61 x 34.6mm Temperature Range – Operating: 0ºC ~ 40ºC; storage: -10°C ~ 50°C Humidity – 0%～95% (no condensation) Certification – UL Some […]
