OmniLink Bridge

Provides time sync, logging, web service API, and MQTT bridge for HAI/Leviton OmniPro II controllers

Download

You can download the binary here or use docker to build an image from git.

Requirements

• .NET Framework 4.5.2 (or Mono equivalent)

Operation

• Area, Messages, Units, and Zones are logged to mySQL when status changes
• Thermostats are logged to mySQL once per minute
  • If no notifications are received within 4 minutes a request is issued
  • After 5 minutes of no updates a warning will be logged and mySQL will not be updated
  • If the temp is 0 a warning will be logged and mySQL will not be updated
• Controller time is checked and compared to the local computer time disregarding time zones

Notifications

• Supports email, prowl, and pushover
• Always sent for area alarms and critical system events
• Optionally enable for area status changes and console messages

Installation Windows

1. Copy files to your desired location like C:\OmniLinkBridge
2. Edit OmniLinkBridge.ini and define at a minimum the controller IP and encryptions keys
3. Run OmniLinkBridge.exe to verify connectivity
4. Add Windows service
   • sc create OmniLinkBridge binpath=C:\OmniLinkBridge\OmniLinkBridge.exe
5. Start service
   • net start OmniLinkBridge

Installation Linux

1. Copy files to your desired location like /opt/OmniLinkBridge
2. Configure at a minimum the controller IP and encryptions keys
   • vim OmniLinkBridge.ini
3. Run as interactive to verify connectivity
   • mono OmniLinkBridge.exe -i
4. Add systemd file and configure paths
   • cp omnilinkbridge.service /etc/systemd/system/
   • vim /etc/systemd/system/omnilinkbridge.service
   • systemctl daemon-reload
5. Enable at boot and start service
   • systemctl enable omnilinkbridge.service
   • systemctl start omnilinkbridge.service

Docker

1. Clone git repo and build docker image
   • git clone https://github.com/excaliburpartners/OmniLinkBridge.git
   • cd OmniLinkBridge
   • docker build --tag="omnilink-bridge" .
2. Configure at a minimum the controller IP and encryptions keys. The web service port must be 8000 unless the Dockerfile is changed.
   • mkdir /opt/omnilink-bridge
   • cp OmniLinkBridge/OmniLinkBridge.ini /opt/omnilink-bridge
   • vim /opt/omnilink-bridge/OmniLinkBridge.ini
3. Start docker container
   • docker run -d --name="omnilink-bridge" -v /opt/omnilink-bridge:/config --net=host --restart unless-stopped omnilink-bridge
4. Verify connectivity by looking at logs
   • docker container logs omnilink-bridge

MySQL Setup

You will want to install the MySQL Community Server, Workbench, and ODBC Connector. The Workbench software provides a graphical interface to administer the MySQL server. The OmniLink Bridge uses ODBC to communicate with the database. The MySQL ODBC Connector library is needed for Windows ODBC to communicate with MySQL.

http://dev.mysql.com/downloads/mysql/ http://dev.mysql.com/downloads/tools/workbench/ http://dev.mysql.com/downloads/connector/odbc/

At this point we need to open MySQL Workbench to create the database (called a schema in the Workbench GUI) for OmniLinkBridge to use.

1. After opening the program double-click on "Local instance MySQL" and enter the password you set in the wizard.
2. On the toolbar click the "Create a new schema" button, provide a name, and click apply.
3. On the left side right-click on the schema you created and click "Set as default schema".
4. In the middle section under Query1 click the open file icon and select the OmniLinkBridge.sql file.
5. Click the Execute lighting bolt to run the query, which will create the tables.

Lastly in OmniLinkBridge.ini set mysql_connection. This should get you up and running. The MySQL Workbench can also be used to view the data that OmniLink Bridge inserts into the tables.

mysql_connection = DRIVER={MySQL ODBC 8.0 Driver};SERVER=localhost;DATABASE=OmniLinkBridge;USER=root;PASSWORD=myPassword;OPTION=3;

Web Service API

To test the API you can use your browser to view a page or PowerShell (see below) to change a value.

• http://localhost:8000/ListUnits
• http://localhost:8000/GetUnit?id=1
• Invoke-WebRequest -Uri "http://localhost:8000/SetUnit" -Method POST -ContentType "application/json" -Body (convertto-json -InputObject @{"id"=1;"value"=100}) -UseBasicParsing

This module will also publish discovery topics for Home Assistant to auto configure devices.
