HomeWizard to EnergyId

hw2energyid is small tool to synchronize data from HomeWizard devices to your EnergyID dashboard.

Since HomeWizard devices API are only available within your local network, using an EnergyID App to synchronize the data is not possible.
hw2energyid helps bridge the gap by reading the data from your local network and sending them to EnergyId using the WebHook App

Prerequisites

EnergyID

Before you start, you need to create a webhook in EnergyID to let the tool push the data to your dashboard.

1. Go to the EnergyId incoming webhook page and click activate.
2. Pick the record you would like to send readings to (e.g.: Home), and provide a name for your application or device (e.g.: HomeWizard).
3. Copy the generated Webhook URL.

Node

To run the tool, you will also need to have NodeJS installed

Usage

You can either run the tool in the console using the NPM script or use the Docker image.

NPM Script

Open a terminal/console and run the following script:

npx hw2energyid --energyid=<url of the webhook> <options>

Options

Option	Alias	Description
--energyid	-e	The URL of the EnergyID Webhook
--meter	-m -p --p1	The name or IP address of the Homewizard meter
--offset	-o	Add an offset to the meter's value (to compensate for consumption before installation)
--dry-run	-d	Dry run. No data will be sent to EnergyID
--recurring	-r	Run the tool every hour
--help	-h	Show help
--version	-v	Show version number

Docker

First, you need to retreive the IP address of your Homewizard meter.

Note

The hostname is formatted as -<last 6 characters of serial>, so devices with serial AABBCCDDEEFF the hostname is as following:

Device	Example hostname
P1 meter	p1meter-DDEEFF
Energy Socket	energysocket-DDEEFF
Watermeter	watermeter-DDEEFF
kWh meter (single phase)	kwhmeter-DDEEFF
kWh meter (three phase)	kwhmeter-DDEEFF

Open a terminal/console and run the following script:

ping <product-name>-<last 6 charachter of serial>

Create a docker compose file with the following content:

version: '3'

services:
  hw2energyid:
    image: ghcr.io/th3s4mur41/hw2energyid
    environment:
      - energyid=<the URL of the EnergyId webhook>
      - meter=<the IP address of the  Meter device>
    network_mode: host
    dns:
      - 1.1.1.1

Note
The dns section is required to resolve the EnergyId webhook URL. If you are using a different DNS server, replace

Environment Variable	Description
energyid	The URL of the EnergyID Webhook
meter	The IP address of the Homewizard meter

Examples

Note
hw2energyid currently only supports synchronizing electricity and water readings

P1 Meter

The HomeWizard P1 Meter connects into the P1 port on your smart meter and shows your electricity and gas usage.

The P1 meter can be discoverd on your network using Multicast DNS (mDNS).
The name of the device is 'hw-p1meter-' followed by the last six charachters of its serial number.

Note
To find the serial number, open your HomeWizard Energy App.
Then go to Settings > Meters > P1 meter

Now that you have all the data you need. Open a terminal/console and run the following script:

npx hw2energyid --meter=hw-p1meter-<last 6 charachter of serial> --energyid=<url of the webhook>

E.g.: The command with your data should look similar to this:

npx hw2energyid --meter=hw-p1meter-65d8c7 --energyid=https://hooks.energyid.eu/services/WebhookIn/46535693-fe25-48ba-96fa-ea827e987318/OS753GD97A11

Water Meter

The HomeWizard Water Meter reads your analog water meter.

The Water meter can be discoverd on your network using Multicast DNS (mDNS).
The name of the device is 'watermeter-' followed by the last six charachters of its serial number.

Now that you have all the data you need. Open a terminal/console and run the following script:

npx hw2energyid --meter=watermeter-<last 6 charachter of serial> --energyid=<url of the webhook>

E.g.: The command with your data should look similar to this:

npx hw2energyid --meter=watermeter-65d8c7 --offset=22.334 --energyid=https://hooks.energyid.eu/services/WebhookIn/46535693-fe25-48ba-96fa-ea827e987318/OS753GD97A11
