Lutron Caseta Bridge Pro Custom Component Install


Hey everyone, I just finished a Home Assistant install (0.83.2) in virtualenv on a FreeNAS 11.2 jail yesterday, so far so good. Still very new to all of this.

I got stuck on trying to configure a Lutron Caseta Pro hub/bridge, following the upsert custom component method. After dumping the files into the custom_components directory alongside my configuration.yaml and attempting to restart HA via the GUI, here’s what the log reports:

I doubled checked my config, IP and mac address check out:

## Lutron Caseta Pro
      - host:
        mac: !secret mac_address

“Telnet Support” in the app is enabled. I have a duckdns hostname set up with SSL and port forwarding, all working as expected as far as I can tell. I looked at other faqs and posts, thankfully didn’t see any call for port forwarding or anything to the bridge.

Any ideas what I might be missing? Thanks in advance!


Bump. Anyone have any ideas? Still can’t seem to get this custom component installed. I’d be super grateful for any help.


I narrowed this down to an issue with “asyncio” and it not cooperating with multithreading? I overcame this by changing line 101 in from:

loop = asyncio.get_event_loop()


loop = asyncio.new_event_loop()

I don’t know enough about this configuration to foresee whether or not this will create issues down the road, but it finally got me to the Lutron configurator on HASS.
