Lutron Integration errors

Configuration
1

Hi all,

Brand new to HA. First big integration I have attempted to configure was Lutron. I have RA2 everywhere in my house. The initial integration setup appeared to work without issue. 123 devices were recognized and imported. However, when I attempt to control anything, nothing happens. I will toggle a light, shade, etc. and the toggle will flip back off after a few seconds.

Checking the logs reveals tens of thousands of errors. The one with the most entries is the following:

Logger: pylutron

Any idea what’s going on? It’s nice that I can see all the Lutron details in HA, but if I can’t actually control anything it obviously won’t be of much value.

I’m having the exact same problem. I just tried integration today. Let me know if you figure anything out and I’ll do the same!

i’ve found getting lutron initial config to be tricky, but once done, pretty reliable. it’s been a while (over a year for me) so my memory here is old but since no one else has reponded i’ll give it a shot…

first, do you know what integration you’re using? are you using this one:
Lutron - Home Assistant?

if you’re not sure, go to your lutron integration page and hit the “documentation” link on the left:

next, do you recall if you connected to the main repeater? or did you connect to the lutron smartbridge? you should connect to the repeater directly, not to the bridge if i recall (i made that mistake myself initially).

FYI - This was related to a bug in the Lutron integration. I just updated to 2024.10.2 and it fixed the issue for me! Now it all seems to work as it should!

Trying to get started with HA. Have RA2 system. Having the exact same issue with the same error codes rapidly occurring.

I’m on 2024.11.1.

@ColeSlaw Did you just update and it all started working?

@timber_pledge any luck?

Update - I got it to work.

Looks like the default login (lutron:integration) was populating all of the lutron devices, but it wasn’t actually working. Seems that the Lutron Connect Bridge uses the default connection and that it doesn’t like to share. I needed to log in to my lutron project and create a new dedicated telnet user. Everything seems to be working now.

Side note, it only took a couple hours to complete the Lutron RA2 Level 1 certification which let me mess around with my project.

Glad you got it working! I was able to update and it worked for me.

I might have to get certified also, thanks for the info!

Beyond getting HA working, I think biggest pro of getting certified is that I think I can now complete a few rooms that seemed silly to install RA2 dimmers in when I had to pay for dealer’s time.

I’m now getting this error. Everything was working fine until I updated to the latest version a couple of weeks ago (after not updating for months). I’m on Core 2024.11.3 and Supervisor 2024.11.4. I have a custom Telnet login and password set up on the main repeater. Here’s the error I get in the log - similar to the one above but different line numbers:

EDIT: I rolled back to 2024.4.3 and it’s working again! Looks like I’ll have to stay on that version until this is figured out for everyone!
