# P1 Monitor

> P1 Monitor is a built-in integration for Home Assistant. It has 340 installs sharing analytics and works locally.

P1 Monitor is a built-in integration that reads data from a P1 Monitor installation on the local network. It adds sensors for energy use and production, covering consumption by day and in total, and current load on each of the three phases. Readings are split by high and low tariff, and there are also sensors for the energy price in each tariff. Setup happens in the UI and asks for the host address or name and the port of the P1 Monitor installation. A diagnostics file can be downloaded to attach to a bug report.
