The Smart Meter ESPHome Edition

This P1 energy meter connects to P1 port and integrates seamlessly with Home Assistant. It is Plug and Play. The ESPHome edition is pre-installed with ESPHome. After connecting to your wifi network, it is recognized in Home Assistant and can be easily added. The P1 energy meter allows you to visualize all the data from your smart meter.

This P1 consumption manager works on all smart meters in Europe such as in the Netherlands, Belgium, Luxembourg, Austria, Sweden, Finland, Lithuania, Denmark, Hungary, Ireland and Switzerland.

The firmware is completely open source. So you can customize these yourself if needed. Also, all data remains local. Privacy is thus guaranteed.

Note: Our pre-installed ESPHome firmware works on most smart meters. It regularly happens that smart meters deviate from the standard. In that case, the ESPHome code will have to be modified. So you are a true tweaker and able to troubleshoot on your own. After we process the order, you will receive the ESPHome code placed by us via email. You can customize these as you wish. Our Smart Meter WiFi Gateway automatically corrects anomalies. So this is not the case with the ESPHome version.

The following data is transmitted every second by the ESPHome version:

  • consumption per phase in kW
  • production of solar panels per phase in kW
  • Current per phase
  • Span per phase
  • total consumption
  • total production
  • main meter peak consumption
  • main meter off-peak consumption
  • main meter peak production
  • main meter off-peak production
  • gas meter (if any)
  • water meter (if present, only in Belgium)

How does it differ from the Smart Meter WiFi gateway?

Smart Meter WiFi gateway
is fully developed by Smart Gateways and can be paired with an unlimited number of home automation solutions. The ESPHome edition is only compatible with Home Assistant. The ESPHome firmware is not developed by us but operates on the same hardware based on a powerful ESP32. We do not provide support on the ESPHome edition. If you have questions about the ESPHome firmware, you can visit the many user forums.

The dashboards on our support page are not released for the ESPHome edition because they are compatible with the original Smart Meter WiFi Gateway. This allows us to offer this version very economically. Of course, there is hardware warranty on the ESPHome edition.

Retrofit to the full version of our
Smart Meter WiFi gateway
is possible, the cost is 15 euros. To do so, please contact us via the

Do the configuration near an access point to make sure the Wi-Fi signal strength is sufficient. If the gateway is connected to WiFi, the gateway can be connected to the P1 port of the smart meter.
