Open-source Ubidots alternatives

DGIoT is an open-source industrial Internet of Things platform. It collects data from machines and sensors using industrial protocols such as Modbus, OPC UA and MQTT, with the project advertising support for more than 300 protocols, and it is aimed at factories, energy sites and system integrators building monitoring and control applications.

The README describes an aggregation engine built on Erlang/OTP in which every device gets its own process acting as a shadow, with an ontology layer that covers data, logic and action, and security with roles and access control. It stores time series data in TDengine, and topics reference digital twins, edge computing, SCADA and low-code configuration. Documentation includes architecture diagrams, storage design and station simulation.

DGIoT is licensed under Apache-2.0 and is deployed on your own servers, with a vendor website in Chinese. It suits industrial IoT teams who want an open platform for device connectivity, rules and visualization.

Mycodo is an environmental monitoring and regulation system written in Python. Its topics point to use on a Raspberry Pi with sensors, relays and PID control, so that conditions such as temperature or humidity can be measured, logged and kept near a target.

The project is tagged for cultivation use cases including plants, hydroponics and mushroom growing, and it provides graphs, timers and time-series measurements. It is released under GPL-3.0. Little documentation was available to summarize here, so details of supported hardware and setup are best checked in the project's repository.
