Design

• Control processor: console, MQTT, etc.
• Data processor: To fetch, process, and publish data
• Pipeline: To link data processors together

Feature

• MQTT controller (Plain/TLS/Websocket)
• Console controller (Authentication)
• Websocket controller (Authentication)
• System/Appliation Upgrade (Remote SW repository)
• Configuration storage
• Data storage (Data retention)
• Json/MessagePack pack
• Zlib compressor
• COV(change of value) publish
• Buffer/Group publish
• Log rotate
• Proxy support by FRP
• Monitor by NodeExporter
• VPN by WireGuard
• Websocket proxy (e.g. for noVNC)
• Modbus TCP/RTU(ASCII)/RTU(ASCII) over TCP
• Simens S7
• Kafka publisher
• MQTT publisher
• File publisher
• OPCUA: Binding open62541
• Python runtime
• HTTP data acquisition
• BACnet: Binding bacnet-stack
