dbus-iobroker-smartmeter

Integrate any smartmeter which is connected to iobroker.

Purpose

With the scripts in this repo it should be easy possible to install, uninstall, restart a service that . Idea is pasend on @RalfZim project linked below.

Inspiration

This project is my first on GitHub and with the Victron Venus OS, so I took some ideas and approaches from the following projects - many thanks for sharing the knowledge:

• https://github.com/kopierschnitte/venus.dbus-senec-enfluri
• https://github.com/RalfZim/venus.dbus-fronius-smartmeter
• https://github.com/victronenergy/dbus-smappee
• https://github.com/Louisvdw/dbus-serialbattery
• https://community.victronenergy.com/questions/85564/eastron-sdm630-modbus-energy-meter-community-editi.html

Install & Configuration

IO-Broker

• configure simple api plugin for api broker

• include the power consumption and energy sold/bought objects into iobroker. Implementing this differs on your situation. There are a lot of options depending on your hardware. Examples:

  • Shelly: https://github.com/iobroker-community-adapters/ioBroker.shelly
  • Fronius: https://github.com/iobroker-community-adapters/ioBroker.fronius
  • Kostal: https://github.com/StrathCole/ioBroker.plenticore
  • Senec: https://github.com/nobl/iobroker.senec/
  • Smartmeter: iobroker smartmeter plugin

Venus/GX

• Get Superuser rights on your CCGX device (https://www.victronenergy.com/live/ccgx:root_access#set_access_level_to_superuser)
• Configure root password
• Get the code from github
• change config.ini as per your settings (see Config-INI Details)
• Connect via winscp (or similar ssh clients) and copy over the code to /data/dbus-iobroker-smartmeter
• Possibly adjust the execution rights on install.sh (e.g. via winscp)
• Execute install.sh script

Config-INI Details

• All IOBroker Paths are referencing to the full path of the iobroker object
• IOBrokerPathSmartMeterId --> Unique ID (serial) used - can e.g. be the serial of the smart meter
• IOBrokerPathOverallConsumption --> Consumption of all three phases in W
• IOBrokerPathPhase1 --> Consumption on phase 1 in W
• IOBrokerPathPhase2 --> Consumption on phase 2 in W
• IOBrokerPathPhase3 --> Consumption on phase 3 in W
• IOBrokerPathGridSold --> Total Sold in kWh
• IOBrokerPathGridBought --> Total Bought in kWh

Additionally the parameter IOBrokerHostPath must give the absolute URL to your IOBroker instance.

How it works

My setup

• iobroker smartmeter plugin ( https://github.com/Apollon77/ioBroker.smartmeter )
• iobroker simple api plugin ( https://github.com/ioBroker/ioBroker.simple-api )
• any ir reader for the smartmeter https://www.ebay.de/itm/125077162292

Details / Process

As mentioned above the script is inspired by @RalfZim and @kopierschnitte fronius smartmeter implementation. So what is the script doing:

• Running as a service
• connecting to DBus of the Venus OS com.victronenergy.grid.http_40
• After successful DBus connection, IOBroker smartmeter values are accessed.
• Serial is taken from the response as device serial
• Paths are added to the DBus with default value 0 - including some settings like name, etc
• After that a "loop" is started which polls iobroker data every 1000ms from the REST-API and updates the values in the DBus

Thats it 😄
