Lutron HomeWorks RS232 to MQTT Bridge

ernstdb · November 2, 2016, 1:29am

There probably isn’t much of an audience for such an old home automation system, but if you have an old Lutron HomeWorks (cira mid 1990’s) in your home you can link it with Home Assistant now. I uploaded to GitHub a Python script (runs as a daemon) that will make the HomeWorks panel available via MQTT. I have HASS running on a RaspberryPi, so naturally I have my RS232 connection to HomeWorks from the same RPi and this Python script running there too.

Lights / Switches are easy defined with:

      - platform: mqtt
        name: "basement"
        state_topic: "homeworks/panel/1/device/3/status"
        command_topic: "homeworks/panel/1/device/3/switch"
        brightness_state_topic: "homeworks/panel/1/device/3/brightness/status"
        brightness_command_topic: "homeworks/panel/1/device/3/brightness/set"
        payload_on: "ON"
        payload_off: "OFF"
        optimistic: false

Enjoy!

Believe it or not, I’ve actually been looking for a way to integrate the original Homeworks into a home automation setup using MQTT and Home Assistant. I’m very excited to experiment with this!

I have your python bridge up and running, but want to view the logs. Could you advise on how/where to view the log? It’s been a while since I’ve coded up some python. I’ve looked at the basic file logging documentation in python regarding adding handlers, but want to see how/where the logs go at the moment.

I answered my own question. I changed the logging line that was commented out to read:

logging.basicConfig(filename='/opt/homeworks/homeworks.log', filemode='w',format='%(asctime)s %(message)s', level=logging.DEBUG)

and now it logs to /opt/homeworks/homeworks.log. I’ll test it out and report back!

So… how far did you get?

Is your HW installation a single panel or multiple panels? I’ve got only one here.

I actually installed everything and got it running at my parents’ house. They have an old Homeworks system (without ethernet) and it seems to have at least two panels – one per floor. I installed the python script into /opt/homeworks and followed your instructions to install the service. It looks like the service starts up and based on the logging (provided below) is able to enumerate devices on the system. However, the service seems to crash at some point and exits without logging any data.

I also don’t see any data on my Mosquitto MQTT server. I have everything running on a Raspberry Pi 2 using the Hassbian image. I’m open to any suggestions!

This is what their processor looks like. I’ve connected the Raspberry Pi to Link 3 at 115200 bps using a USB <–> Serial Adapter (PL2303 chipset). I can query the controller at this bitrate using the serial connection outside the python script you wrote. Any suggestions on where to go next?
