P1 Monitor

The P1 Monitor integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] allows you to gather data from your P1 Monitor device and use it in Home Assistant.

P1 Monitor is a piece of software that can be installed on a Raspberry Pi or other Linux-based system. It reads the data from your smart meter via the serial port (P1), such as your energy consumption, but also that of gas or a water meter.

Configuration

To add the P1 Monitor integration to your Home Assistant instance, use this My button:

Manual configuration steps

If the above My button doesn’t work, you can also perform the following steps manually:

  • Browse to your Home Assistant instance.

  • Go to Settings > Devices & Services.

  • In the bottom right corner, select the Add Integration button.

  • From the list, select P1 Monitor.

  • Follow the instructions on screen to complete the setup.

Host

The IP address or hostname of your P1 Monitor instance.

Port

The port number of your P1 Monitor instance. The default port is 80.

Data updates

The integration will poll your P1 Monitor instance every 5 seconds to update the data in Home Assistant.

Sensors

The P1 Monitor platform mainly provides sensors that you can use in your energy dashboard.

SmartMeter

Read out what your meter readings are for energy consumption/yield, see what your current power consumption is and in which tariff period you are currently.

  • Gas Consumption (m3)
  • Power Consumption / Production (W)
  • Energy Consumption Low/High (kWh)
  • Energy Production Low/High (kWh)
  • Energy Tariff Period (low / high)

Note

By default, the gas consumption entity is disabled. To use it, you need to enable it.

Phases

See per phase what your voltage, current and power consumption/production is.

  • Voltage phases L1/2/3 (V)
  • Current Phases L1/2/3 (A)
  • Power consumed phases L1/2/3 (W)
  • Power Produced phases L1/2/3 (W)

WaterMeter

Important

You need to run at least version 1.1.0 of P1 Monitor, to use a water meter.

See how much water you consume per day, in total and the number of counted pulses.

  • Water Consumption - day (liters)
  • Water Consumption - total (m3)
  • Pulse Count

Settings

You can use the rates set in P1 Monitor for your calculations in Home Assistant.

  • Gas Consumption Price
  • Energy Consumption Price Low/High
  • Energy Production Price Low/High

Removing the integration

This integration follows standard integration removal. No extra steps are required.

To remove an integration instance from Home Assistant

  1. Go to Settings > Devices & services and select the integration card.
  2. From the list of devices, select the integration instance you want to remove.
