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

OmniLink Bridge is divided into the following modules and configurable settings. Configuration settings can also be set as environment variables by using their name in uppercase. Refer to OmniLinkBridge.ini for specifics.

• OmniLinkII: 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
• Time Sync: time_
  • Controller time is checked and compared to the local computer time disregarding time zones
• MQTT: 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
• Web API: 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
• Logger
  • Console output: verbose_
    • Enabled by default
    • 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: mysql_
    • Thermostats are logged every minute and when an event is received
  • Push notifications: notify_
    • Always sent for area alarms and critical system events
    • Optionally enable for area status changes and console messages
    • Email: mail_
    • Prowl: prowl_
    • Pushover: pushover_

Docker Hub Quickstart

Quickly get started with console logging by specifying the controller address and encryption keys.

docker run --name="omnilink-bridge" \
  -v /etc/localtime:/etc/localtime:ro \
  -e CONTROLLER_ADDRESS='' \
  -e CONTROLLER_KEY1='00-00-00-00-00-00-00-00' \
  -e CONTROLLER_KEY2='00-00-00-00-00-00-00-00' \
  --net=host excaliburpartners/omnilink-bridge

Or start in the background with time sync and MQTT modules enabled.

docker run -d --name="omnilink-bridge" --restart always \
  -v /etc/localtime:/etc/localtime:ro \
  -e CONTROLLER_ADDRESS='' \
  -e CONTROLLER_KEY1='00-00-00-00-00-00-00-00' \
  -e CONTROLLER_KEY2='00-00-00-00-00-00-00-00' \
  -e TIME_SYNC='yes' \
  -e MQTT_ENABLED='yes' \
  -e MQTT_SERVER='' \
  -e MQTT_USERNAME='' \
  -e MQTT_PASSWORD='' \
  --net=host excaliburpartners/omnilink-bridge

Docker Hub with Configuration File

1. Configure at a minimum the controller IP and encryptions keys.

mkdir /opt/omnilink-bridge

docker run -d --name="omnilink-bridge" -v /opt/omnilink-bridge:/config -v /etc/localtime:/etc/localtime:ro --net=host --restart always excaliburpartners/omnilink-bridge

3. Verify connectivity by looking at logs

docker logs omnilink-bridge

Docker for Developers

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.

4. Verify connectivity by looking at logs

docker logs omnilink-bridge

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 from the command prompt 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

MySQL

The MySQL ODBC Connector is required for MySQL logging. The docker image comes with the MySQL ODBC connector installed. For Windows and Linux you will need to download and install it.

Configure mysql_connection in OmniLinkBridge.ini. For Windows change DRIVER={MySQL} to name of the driver shown in the ODBC Data Source Administrator.

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

Telemetry

OmniLink Bridge collects anonymous telemetry data to help improve the software. You can opt of telemetry by setting a TELEMETRY_OPTOUT environment variable to 1.
