The Smart Meter ESPHome Edition
This Smart Meter energy gateway connects to the P1 port of your smart meter and seamlessly integrates with Home Assistant. It’s Plug and Play. The ESPHome edition comes pre-installed with ESPHome. After connecting to your Wi-Fi network, it is recognized in Home Assistant and can be easily added. With the P1 energy meter, you can visualize all the data from your smart meter.
This P1 Smart Meter Gateway works with all smart meters in Europe, including the Netherlands, Belgium, Luxembourg, Sweden, Finland, Lithuania, Denmark, Hungary, Ireland, and Switzerland. It can be powered through the P1 port of smart meters (only for DSMR5 meters)
The firmware is completely open source. You can customize it to your needs if necessary. Also, all data remains local, ensuring your privacy.
Please note: The ESPHome firmware pre-installed by us works with most smart meters. However, some smart meters deviate from the standard. In that case, the ESPHome code will need to be adjusted. By using the ESPHome version you acknowledge you are a true tweaker and capable of troubleshooting. After we have processed the order, you will receive the ESPHome code placed by us via email. You can customize it as you wish. Our Smart Meter WiFi Gateway automatically corrects deviations. This is not the case with the ESPHome version.
The following data is transmitted every second by the ESPHome version:
- Phase consumption in kW
- Phase solar panel production in kW
- Current per phase
- Voltage 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 available)
- Water meter (if available, only in Belgium)
What is the difference with the Smart Meter WiFi gateway?
The Smart Meter WiFi gateway is fully developed by Smart Gateways and can be integrated 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 works on the same hardware, based on a powerful ESP32. We do not provide support for the ESPHome edition. If you have questions about the ESPHome firmware, you can visit the various user forums.
The dashboards on our support page are not released for the ESPHome edition because they are designed for the original Smart Meter WiFi Gateway. This allows us to offer this version at a very competitive price. Of course, there is hardware warranty on the ESPHome edition, and a 2-week withdrawal period applies.
Upgrading to the full version of our Smart Meter WiFi Gateway is possible after purchase, and the cost is 15 euros. Please contact us through the contact form for more information.

Manual
It is recommended to configure the Smart Meter ESPHome edition without it being connected to the smart meter, but rather powered through a micro-USB connection (not included). Perform the configuration near an access point to ensure that the Wi-Fi signal strength is sufficient. Once the gateway is connected to Wi-Fi, you can then connect it to the P1 port of the smart meter.
- Connect a USB power supply (5V, 1A) to the micro USB port of the gateway.
- The gateway will now start up; wait for at least 60 seconds.
- The gateway will broadcast the Wi-Fi network “Smart Gateways Smart Meter.” Connect to this network. The password is “smartgateways” without quotation marks.
- A browser will display available Wi-Fi networks. Select your own Wi-Fi network from the list and enter the password. Click ‘Save.’
- If no browser window appears, go to http://192.168.4.1 and enter your Wi-Fi details and click ‘Save.’
- The gateway will now establish a connection to your Wi-Fi network. The blue LED will flash at a 1-second interval if successful.
- If the gateway cannot establish a connection, try again until successful. Hidden Wi-Fi networks are not supported.
- Once the gateway is connected, it will automatically appear within Home Assistant (if it is in the same subnet).
