Lutron Diva 2 sec delay reporting over Telnet on Physical Change - Lutron Responds

[funtime]

I have about 10 Lutron Caseta dimmers and about 5 picos connected to HE. All work fine with motion sensors, RM, and button controller. Added a two Diva Dimmers and when the dimmers are manually operated, there is about a 2 second delay before I see the Telnet events; thus, rules don't trigger in a timely manner.

1. Local physical control of the dimmer is fine.
2. I added one Diva about a month ago and the other today. I didn't notice the problem because I didn't write any rules until today.
3. Hubitat control of On/Off, Start/Stop dim, set dimmer level all work.
4. All other Lutron devices are working normally.
5. Tested the dimmers positioned 5 ft from the Lutron Hub and the delay remains.
6. Reboot lutron hub--no change

I'm stumped as to what to try next. I'd appreciate any ideas

Thanks,

I contacted Lutron Support and they provided a very thorough response. With their permission, I am posting here:

We are sorry to hear you are experiencing issues with your DVRF-6L dimmers experiencing delays in your Hubitat Telnet integration. Unfortunately, this is by design with the Smart Diva dimmers. As opposed to the original-style Caséta dimmers, the new Smart Diva has a physical slider; the inclusion of this physical slider is what causes the delay. Essentially the Lutron app will wait a couple seconds before updating the on/off/dim-level of the Smart Diva in the Lutron app, as otherwise it would most likely be too much RF traffic for the Diva to send an update to the app for every percentage.

For example, a user will lower the dimmer slider on the Diva from full to 50%; the Hub will wait a couple seconds to update the in-app level to represent that it was lowered to 50%. As opposed to the Diva sending a ping back to the Hub multiple times in that couple seconds saying it was set to 99%, then 98%, then 97%, etc. down to 50%.

We apologize for any inconvenience this programming may cause with your integration. Our best recommendation to achieve exactly the Telnet programming you are looking for would be to continue instead using the original-style Caséta devices with the push-button design, as they do have the programming that would be compatible with what you would like out of your system.

Thank you for updating this post. I had planned to replace my Caséta dinners with Diva dimmers, but I’m not going to do that now.

Just seems like bad design. Couldn’t they have programmed it to update the slider position at some maximum frequency, eg 200 ms ?
