Deploy EmonCMS in one click installation.
Open-source web app for logging and visualizing energy, temperature, and environmental sensor data over time.
What you can build with EmonCMS
EmonCMS is the open-source backend of the OpenEnergyMonitor project, built specifically for time-series energy, temperature, and environmental data. Unlike general-purpose dashboards, every component — from input processing pipelines to PHPFina and PHPTimeSeries storage engines — is tuned for years of high-resolution sensor data on modest hardware.
Self-hosting EmonCMS on a VPS keeps household, solar, heat-pump, and IoT measurements entirely under your control, with no per-feed limits or cloud subscriptions. The bundled MQTT broker, MariaDB, and Redis stack accepts data from emonPi, emonTx, ESPHome, Home Assistant, and any HTTP or MQTT-capable sensor.
Key features of EmonCMS
Time-series feeds
Custom PHPFina and PHPTimeSeries engines store years of high-resolution sensor readings far more efficiently than a general SQL database.
MQTT and HTTP inputs
Receive data from emonPi, emonTx, ESPHome, Home Assistant, or any device that can publish MQTT or call an HTTP API.
Input processing
Chain unit conversions, power-to-energy accumulators, rate limits, and virtual feeds without writing code or external scripts.
Dashboards and graphs
Drag-and-drop dashboard editor with multi-series graphs, gauges, and bar charts for live and historical sensor visualization.
Apps for energy use
Prebuilt apps for solar PV, heat pumps, electric vehicles, and household consumption surface insights without manual configuration.
REST API and exports
Read and write every feed through a documented REST API and export raw CSV data for offline analysis or backup.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
