How to: Connecting the Homey Energy Dongle to Home Assistant with ESPHome

Emile_Athom · April 17, 2025, 2:55pm

Hi everyone!

Recently my company launched the Homey Energy Dongle — a P1 to Wi-Fi device made specifically for Homey Cloud & Homey Pro.

While of course it’s primarily designed to provide a seamless experience for Homey users, the hardware can be re-flashed with ESPHome for an all-local experience.

I’m writing this how-to for those who enjoy buying well-designed & well-tested hardware by an established brand, but prefer to use it with their own software.

The Homey Energy Dongle has a USB-C port, that when connected to a PC or Mac, you can use to flash ESPHome from a web browser.

Then, use this config:

esphome:
  name: homey-energy-dongle
  friendly_name: Homey Energy Dongle
  on_boot:
    - priority: -100.0
      then:
        - output.turn_on: p1_input_enable
        - light.turn_on:
            id: led
            red: 0%
            green: 0%
            blue: 100%

esp32:
  board: esp32-c6-devkitc-1
  flash_size: 4MB
  variant: esp32c6
  framework:
    type: esp-idf
    version: 5.3.1
    platform_version: 6.9.0
    sdkconfig_options:
      CONFIG_ESPTOOLPY_FLASHSIZE_4MB: y

ota:
  - platform: esphome
    password: "..." # Your OTA Password

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

external_components:
  - source: github://oxan/esphome-stream-server

stream_server:
  - uart_id: p1_input
    port: 1234
    buffer_size: 256

uart:
  - id: p1_input
    rx_buffer_size: 256
    rx_pin:
      number: GPIO4
      inverted: true # You might need to flip this to `false` for some meters
    baud_rate: 115200 # Change this to 9600 for DSMR v2 meters.
  - id: p1_output
    tx_pin:
      number: GPIO3
      inverted: true
    baud_rate: 115200

output:
  - id: p1_input_enable
    platform: gpio
    pin:
      number: GPIO23
      mode: output

light:
  - id: led
    name: "LED"
    platform: esp32_rmt_led_strip
    rgb_order: GRB
    pin: GPIO2
    num_leds: 1
    chipset: ws2812

This will let the Homey Energy Dongle create a TCP server on port 1234. Every DSMR telegram will be broadcasted to all clients. You can test this with e.g. nc 192.168.0.100 1234 in a console on macOS.

Then, to import the data into Home Assistant, add the DSMR Smart Meter integration, and enter your device’s IP with port 1234. And your smart meter data, such as live usage (W), consumed electricity (kWh) and gas usage (m3) should appear inside Home Assistant.

Happy hacking! ^.^

Notes

To revert back to the original firmware, visit usb.homey.app.
I haven’t managed to get DSMR Passthrough working yet. I’m not very experienced with ESPHome, so maybe some wizard can take a look.
When returning your product to a store, please factory reset using usb.homey.app. We really don’t want frustrated customers why their ‘Second Chance’ product doesn’t work with Homey.
The reason the ESPHome DSMR component isn’t used, is because it requires the Arduino framework. However, the Arduino framework does not yet work with the newest ESP32-C6.

Hi @Emile_Athom and thanks for the open discussion - it’s great to see such transparency and flexibility with the Homey Energy Dongle!
As a user, I always want to get as more as possible from devices I own.
Quick question: does this openness also mean we could use the dongle with ESPHome to read M-Bus data from a Landis+Gyr E450 meter? Since that model isn’t natively supported in Homey, I’m curious if the stream server setup might work with a suitable ESPHome config, or if additional hardware or firmware support would be required.
Appreciate any thoughts or insights!

RogueSheep · July 22, 2025, 6:08pm

Hi @Emile_Athom,
Thanks for that info.
I have just activated my HomeAssistant Green so I am very fresh to HomeAssistant and ESP devices.
Trying to follow your instructions in order to connect the Homey dongle.
I connected to the dongle using web.ESPhome.io (in Chrome), after I clicked 'Prepare for first use’, it first reports ‘Configuration installed’ but then when it tries to connect I get ‘An error occurred. Improv Wi-Fi Serial not detected’.
I tried several usb cables here including one for an usb drive (which should be able to handle both power and data)

Should I be taking others steps first or take a different route to flashing the dongle?

Thanks,
Pascal

r8805 · July 28, 2025, 7:59am

Hey Pascal! You need to press the reset button located next to the USB-C connection with a sim ejection tool or similar while connecting the cable. That will put the device in a state where it’s ready to be flashed with new firmware. Note that the LED indicator won’t turn on.

I did manage to flash the dongle with ESPHome, but haven’t yet been able to connect it with DSMR Smart Meter.

comatose_tortoise · August 12, 2025, 6:07am

Has anyone gotten this to work? I’m searching for good quality P1 electricity dongles, having bad luck with smartgateway ones.

r8805 · August 12, 2025, 2:57pm

I actually got mine running. My issue was that I had to activate the P1 port on my meter. Once it was activated my flashed Homey Energy Dongle started feeding the Home Assistant DSMR plugin.

comatose_tortoise · August 12, 2025, 3:13pm

Nice! Choosing between this and one of the ”slimmelezer” someone is selling. https://www.zuidwijk.com/product-category/webshop/

r8805 · August 18, 2025, 7:55am

Did a quick write-up here on how I got it running at home: Homey Energy Dongle with Home Assistant

msasdk · November 28, 2025, 1:05pm

Thanks for this!
Does the DSMR component now work on c6? Arduino framework now supports c6. Also, does the output work?

Thak you for your write-up. I have done many attempts with 2 different cables, both on my macbook with google chrome as directly connected to the home assistant green.

In the best case “preparing installation” keeps on spinning after this sequence: “+new device > jtag/serial debug unit > connect > connecting > preparing installation”

Do you have an idea what is going wrong?

Also when I click skip initially to be able to select “ESP32-C6”. Also when following this step the ESPhome creates a device but it is offline. I can click edit, add the code, click save and install. Connecting spins and then continues to preparing installation but then hangs.

Fetjesus · January 20, 2026, 6:54pm

Grymt. Why don’t the original file not work in Sweden?
I have managed to set it up, however when I try to connect to it with the right ip and port 1234 and DSRM-version 5 I get cant connect. “det gick inte att ansluta”. Did you get this error too?

Also I see that you don’t assign the port 1234 in your file?

msasdk · January 22, 2026, 3:58pm

Tja!

I vaguely remember that the original config from @Emile_Athom did not work for me either, but the slightly modified version from @r8805 in worked.

Anyhow, this approach is now less relevant as these two configs are using an external component that streams the data on a specific port. My config is using the esphome native dmsr component. Previously this was not possible as it was as it was built on top of the Arduino framework which did not support esp32-c6. In the 2026.1.0 release of esphome, the dsmr component is now migrated over to esp-idf.

My config should be modified from of 2026.1.0 as following, however, I have not yet had the time to try.

esphome:
  name: dsmr_p1
  friendly_name: Energy Dongle
  on_boot:
    - priority: -100.0

same here @kfarbridges-ha . Did you eventually find a solution to the spining Preparing Installation?

honda4life · February 12, 2026, 6:44am

TX is on GPIO5 non-inverted
You can’t use both (telnet and TX), that’s a limitation of ESPHome.
GPIO22 is high when no dongle connected and becomes low when data is requested

Hi guys,

So I am completely lost here.

I have a Homey dongle, it working fine.

I decided I want to add it to home assistant.

What I get so for:

I flash it on Web - ESPHome.
I can prepare for first use. Installs fine, set up wifi with no issues.
