P1 Monitor Download: How to Monitor Your Smart Meter Data
If you have a smart meter installed in your home, you might be interested in monitoring your energy consumption and production in real-time. This can help you save money, reduce your carbon footprint, and optimize your energy usage. One way to do this is by using P1 monitor, a software project that runs on a Raspberry Pi and connects to your smart meter via the serial port (P1). In this article, we will explain what P1 monitor is, how to download and install it, how to use it, and what are its features and benefits. We will also mention some alternatives to P1 monitor that you might want to consider.
What is P1 Monitor?
P1 monitor is a software project that allows you to read the data from your smart meter via the serial port (P1), such as your electricity and gas consumption, but also that of water or solar panels if you have them. The software monitors the telegrams sent by the meter via serial interface, interprets them and stores the data in a SQLite database running in memory. The data is then displayed on a web page that you can access from any device on your local network. You can also export the data to CSV files or use an API to integrate it with other platforms.

How to Download and Install P1 Monitor on a Raspberry Pi
To use P1 monitor, you need a Raspberry Pi 3 or 4 with an SDHC card of at least 8GB (preferably 16GB or 32GB). You also need a P1 cable that connects your smart meter to the Raspberry Pi via USB. You can buy one online or make one yourself if you have the skills and materials. Here are the steps to download and install P1 monitor on your Raspberry Pi:
Download the latest P1 monitor image file from . It is a zip file that contains the software and instructions.
Unzip the file and read the attachments.
Copy the p1monYYYYMMDD-NN.NN-X.img file to the SDHC card using a tool like USB Image Tool or balenaEtcher. This will overwrite any data on the card, so make sure you back up anything important.
Place the SDHC card in the Raspberry Pi.
Connect the P1 cable to the smart meter and the Raspberry Pi.
Start the Raspberry Pi with network and power cables attached.
Find the IP address of the Raspberry Pi using a tool like Angry IP Scanner or Fing, or check your router's settings.
Enter the IP address in your web browser (Chrome, Firefox, etc.) to access P1 monitor's web page.
Optional: Import your data from a previous version of P1 monitor if you have used it before.
How to Use P1 Monitor to Access and Visualize Your Energy Data
Once you have installed P1 monitor on your Raspberry Pi and connected it to your smart meter, you can use it to access and visualize your energy data. P1 monitor has several screens where you can see the current and historical values of your energy consumption and production. You can also enter some settings like tariffs, costs, device IDs, etc. Here are some examples of what you can see on P1 monitor's web page:
Current consumption: This screen shows how much electricity power you are using (left top), how much power you have used today and how much it costs. At the bottom, it shows the current consumption of the last 4 hours in a graph.
Home: This screen shows both your consumption and production of electricity power. This is useful if you have solar panels or a wind turbine. It also shows the net power, which is the difference between consumption and production. If it is positive, you are using more power than you produce. If it is negative, you are producing more power than you use. You can also see the current and daily values of gas and water consumption.
History: This screen shows the historical data of your energy consumption and production in different time periods: day, week, month, year, and custom. You can see the graphs of power, energy, costs, CO2 emissions, etc. You can also compare different periods or devices.
Phases: This screen shows the data of each phase of your electricity connection. You can see the voltage, current, power factor, frequency, etc. of each phase. This can help you detect any imbalance or problem in your connection.
Devices: This screen shows the data of each device that you have connected to P1 monitor via MQTT or API. You can see the power, energy, costs, etc. of each device. You can also add or remove devices.
Settings: This screen allows you to enter some settings for P1 monitor, such as tariffs, costs, device IDs, passwords, backup options, etc.
What are the Features and Benefits of P1 Monitor
P1 monitor is a software project that has many features and benefits for smart meter users. Here are some of them:
It is free and open source. You can download it from and use it without any cost or limitation. You can also modify it or contribute to it if you have the skills and interest.
It is easy to install and use. You only need a Raspberry Pi 3 or 4, a P1 cable, and an SDHC card to run it. The installation process is simple and straightforward. The web page is user-friendly and intuitive.
It is compatible with most smart meters in the Netherlands and Belgium that have a P1 port. It supports DSMR 2.x, 3.x, 4.x and 5.x protocols.
It is secure and reliable. The data is stored locally on the Raspberry Pi and not sent to any third-party server or cloud service. The web page is password-protected and encrypted with HTTPS.
It is flexible and customizable. You can adjust the settings to suit your preferences and needs. You can also export the data to CSV files or use an API to integrate it with other platforms.
It is informative and insightful. You can access and visualize your energy data in real-time and in different time periods. You can also compare different periods or devices. You can see the costs, CO2 emissions, net power, etc. of your energy usage.
