Enviriot is a low-code platform for device management and process automation.

A device, its settings, a sensor reading and a computed value are all represented the same way — as topics in one tree — so the state of the whole system can be watched and changed in real time. The control logic is drawn as visual diagrams (Logram), and everything else is added by plugins: they attach devices and external systems, store data and history, and serve the user interfaces. Plugins talk to each other only through the topic tree.

Enviriot Server (bin/enviriot.exe)

• Repository. The topic tree, the change queue and the engine tick
• Runs as a console application or as a Windows service
• Plugins discovered and loaded through MEF, started by priority
• JavaScript runtime (NiL.JS) shared by user scripts and Logram blocks
• XST import/export of any subtree

plugin PersistentStorage (bin/PersistentStorage.dll)

• State and manifest storage on LiteDB
• Tree restored at startup, before the plugins that read it
• Backup of the working database before it is opened

plugin Archivist (bin/Archivist.dll)

• Value history
• Rollups over 5 minutes, an hour and a day
• Retention policy
• One query model for both charts and JavaScript

plugin Logram (bin/Logram.dll)

• JavaScript based Logram blocks
• A synchronous processor unit
• Published block catalog

plugin MQTT-SN (bin/MQTT_SN.dll)

• MQTT-SN Broker v1.2
• ZeroConf. Search gateway & DHCP for devices
• GPIO. Digital inputs/outputs, Analog inputs, PWM, UART.
• TWI(I2C)
• ScriptOnDevice

plugin MQTT (bin/MQTT.dll)

• MQTT Client v3.1 and v3.1.1

plugin WebUI (bin/WebUI.dll)

• WebIDE. Tree, Inspector, Logram editor, catalog and log, in the browser
• Dashboard. Pages assembled by the user from ready-made components
• pub/sub over WebSocket
• Charts over the Archivist history
• Dashboard access declared per topic; WebIDE limited to the local network

Both interfaces are served on port 80, falling back to 8080..8089 when it is taken: unpack the release, start enviriot.exe and open http://localhost/.
