Integrate a smartmeter (p1) into Homey

P1 smartmeter

NOTE: This app doesn't get information out of the smartmeter, you have to use an device (a raspberry pi for example) that push data to the app.

Introduction

This app adds the P1 smartmeter into Homey and add an api to update the data. The repository https://github.com/koktaildotcom/com.p1.smartmeter-dsmr.reader reads the data from the p1 and push it to the com.p1.smartmeter api.

Requirements of the device that reads data from the smartmeter (a raspberry pi for example)

1. A working internet connection.
2. A serial (usb) connection with the p1 port of the p1 smartmeter.
3. Power.
4. Cli access to the device.

Script for reading the data and push it to the api (Standalone)

NOTE: This example is for DSMR 4.0 supported devices.

1. Install the script https://github.com/koktaildotcom/com.p1.smartmeter-dsmr.reader on the device connected to the serial p1.
2. Run npm install
3. Change the HomeyId as described in src/p1.js.
4. Change the config.serialPort for your situation (you should check your smartmeter or google around..)
5. Run the script by calling: node src/p1.js

Script for reading the data and push it to the api (DSMR-Reader)

1. Install the script https://gist.github.com/steffjenl/31bd083eeb9d0be04375b7695b9f2eaf as plugin for DSM-Reader.
2. More information about installing plugin's can be found on https://dsmr-reader.readthedocs.io/nl/v3/plugins.html
3. Change the HOMEY_ID as described in forward_raw_telegram_to_api.py.
4. Execute as user dsmr in the dsmr directory ./post-deploy.sh

Usage of the Homey app

1. Install the app com.p1.smartmeter.
2. Add device p1 smartmeter.
3. Use the package com.p1.smartmeter-dsmr.reader to push data com.p1.smartmeter's endpoint /update or /update/dsmrreader.
