ioBroker
ioBroker is an open-source IoT integration platform that connects and automates devices across many protocols and vendors. It uses adapters to bring smart home systems together under one logic engine.
- Hundreds of adapters
- JavaScript automation engine
- Multi-protocol device support
- Flexible visualization
Zigbee2MQTT
Zigbee2MQTT bridges Zigbee devices to MQTT, allowing them to be used without proprietary vendor hubs or bridges. It targets smart home users wanting vendor-neutral Zigbee control. It is deployed via Docker.
- Supports thousands of Zigbee devices
- No vendor hub required
- MQTT integration
- Web-based control panel
