OmniLink Bridge

Provides MQTT bridge, web service API, time sync, and logging for HAI/Leviton OmniPro II controllers. Provides integration with Samsung SmartThings via web service API and Home Assistant via MQTT.

Download

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

Requirements

• Docker
• .NET Framework 4.5.2 (or Mono equivalent)

Operation

OmniLinkBridge is divided into the following modules

• OmniLinkII
  • Settings: controller_
  • Maintains connection to the OmniLink controller
  • Thermostats
    • If no status update has been received after 4 minutes a request is issued
    • A status update containing a temperature of 0 is ignored
      • This can occur when a ZigBee thermostat has lost communication
• Logger
  • Console output
    • Settings: verbose_
    • Thermostats (verbose_thermostat_timer)
      • After 5 minutes of no status updates a warning will be logged
      • When a current temperature of 0 is received a warning will be logged
  • MySQL logging
    • Settings: mysql_
    • Thermostats are logged every minute and when an event is received
  • Push notifications
    • Settings: notify_
    • Always sent for area alarms and critical system events
    • Optionally enable for area status changes and console messages
    • Email
      • Settings: mail_
    • Prowl
      • Settings: prowl_
    • Pushover
      • Settings: pushover_
• Time Sync
  • Settings: time_
  • Controller time is checked and compared to the local computer time disregarding time zones
• Web API
  • Settings: webapi_
  • Provides integration with Samsung SmartThings
  • Allows an application to subscribe to receive POST notifications status updates are received from the OmniLinkII module
    • On failure to POST to callback URL subscription is removed
    • Recommended for application to send subscribe reqeusts every few minutes
  • Requests to GET endpoints return status from the OmniLinkII module
  • Requests to POST endpoints send commands to the OmniLinkII module
• MQTT
  • Settings: mqtt_
  • Maintains connection to the MQTT broker
  • Publishes discovery topics for Home Assistant to auto configure devices
  • Publishes topics for status received from the OmniLinkII module
  • Subscribes to command topics and sends commands to the OmniLinkII module

Docker Hub (preferred)

1. Configure at a minimum the controller IP and encryptions keys. The web service port must be 8000.

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

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};SERVER=localhost;DATABASE=OmniLinkBridge;USER=root;PASSWORD=myPassword;OPTION=3;
