Mycodo
Mycodo is an open-source environmental monitoring and regulation system primarily for Raspberry Pi, designed to sense and control environmental conditions through inputs (sensors), outputs (relays, PWM), and logic functions (PID, conditionals). It provides a web-based dashboard for remote management and has been used for mushroom cultivation, hydroponics, terrariums, and precision temperature control.

What Mycodo is
Python-based system running on Debian-based Linux (Raspberry Pi OS) that couples GPIO inputs and outputs with time-series data logging, PID control loops, and rule-based automation. Includes a web interface with REST API (v1), custom module support, and multi-language translations; data persists to local time-series storage with dashboard visualization and alerting capabilities.

Best use cases
Implementation considerations
- Requires Debian-based Linux (Raspberry Pi OS tested); GPIO hardware and sensor/actuator selection dictates wiring and driver complexity.
- Installation via curl-piped bash script; review security implications before running. Documentation recommends local network deployment; external access requires manual security configuration (HTTPS, authentication hardening).
- Custom Inputs, Outputs, and Functions can be written in Python but require familiarity with the module API and testing methodology.
- Data persists locally to the SBC; no native cloud sync. Backup/restore workflow is manual; plan for storage capacity and SDCARD wear.
- PID tuning and control logic require domain expertise in process control; trial-and-error or professional calibration may be necessary for high-precision applications.
When to avoid it — and what to weigh
- Require Real-time Hard Deadlines — Mycodo is a soft real-time system on general-purpose Linux. Safety-critical or deterministic control (e.g., emergency shutdown <100ms) should use dedicated industrial controllers or interlock hardware.
- Need Enterprise SaaS Multi-tenancy — Mycodo is single-instance, single-user architecture. No native user roles, permissions, or cloud synchronization. Not suitable for commercial SaaS or managed service deployments without significant customization.
- Expect Plug-and-Play Cloud Connectivity — Web interface requires local network or manual VPN/tunnel setup for remote access. No built-in IoT platform integration (AWS, Azure, Google Cloud) or managed backup—users manage infrastructure.
- Depend on Native Mobile Apps — No official iOS or Android app. Remote access relies on web browser or third-party tunneling. Mobile UX is browser-based and not optimized for handheld devices.
License & commercial use
GPL-3.0 (GNU General Public License v3.0). Copyleft license requiring derived works to remain open-source and include license/source disclosure. Allows commercial use of the software itself but mandates sharing of modifications under the same license.
Requires careful review. GPL-3.0 permits commercial deployment, but any modifications to Mycodo or integration into a product must be open-sourced under GPL-3.0. Reselling unmodified Mycodo is permissible; bundling with proprietary software or offering Mycodo-as-a-service may trigger copyleft obligations. Consult legal counsel if monetizing Mycodo-based offerings.

System runs on local network by default; web interface exposed to LAN. No built-in rate-limiting, account lockout, or multi-user access control documented. Installation script pipes curl to bash (common but potential supply-chain risk). Authentication strength depends on OS-level hardening (firewall, SSH key management). Shell script and Python code execution via UI is powerful but risky if non-trusted users have access. No formal security audit or CVE tracking mentioned. TLS/HTTPS configuration is user's responsibility. Requires security review before any internet-facing deployment.
Alternatives to consider
OpenHAB / Home Assistant
General-purpose home automation platforms with broader device support and cloud integration, but less focused on PID control and environmental regulation; steeper learning curve for non-Linux users.
Arduino / PLC-based custom controllers
Lower-level, deterministic control with hard real-time guarantees; better for safety-critical systems. Lacks web UI and data visualization; requires firmware programming.
Commercial SCADA / Greenhouse Control Systems
Purpose-built for agriculture with managed support, multi-site dashboards, and compliance certifications. Significantly higher cost and less customizable for hobbyist or research use.
