Emoncms is an open-source PHP web application for processing, logging and visualising energy, temperature and other environmental sensor data. It is part of the OpenEnergyMonitor project and supports dashboards, feeds, MQTT input, and a REST API for posting and reading time-series data.

Use cases

• log and visualise home energy consumption over time
• build dashboards for temperature and environmental sensor data
• self-host a time-series database for sensor feeds
• monitor a heat pump or solar PV system
• ingest sensor readings via MQTT or HTTP API
• export sensor history to CSV

When to choose

• you want full control and self-hosting of your energy monitoring data
• you use OpenEnergyMonitor hardware like emonPi or emonTx
• you need dashboards and histograms for long-term sensor logs
• you want a Raspberry Pi-friendly low-write logging setup

When to avoid

• you need a general-purpose business analytics or BI tool
• your stack cannot run PHP with MySQL and Apache
• you need high-frequency industrial SCADA-grade data acquisition
• you want a managed cloud service without self-hosting
