Lutron Caseta Bridge Pro Custom Component Install

Configuration
1

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
lutron_caseta_pro:
    bridges:
      - host: 10.0.1.30
        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 casetify.py from:

loop = asyncio.get_event_loop()

to

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.

Thanks for posting this!
I just ran through adding a Caseta Pro and had the exact same issue. This fixed mine as well.
See comments below for further details.

okay, I’m still have issues. The lights showed up on the front end but I can’t control them with this error showing:

for some reason HA can’t connect to the hub

@ThomasPatrick
I ended up solving my problem. It started because a component file was missing. This caused the async issue. But when I found the missing file and fixed it the change to the line 101 in casetify.py caused a new problem that kept HA from connecting to the hub. I changed it back, and now all works as expected
