Ray,
As you know I was an early adopter of your OS controllers with over 25 deployed. Fortunately only 5 are 2.2 and the one 2.1 I had I replaced long ago. While the majority are 3.0 I do have quite a few that are 2.3 and seem to be functioning well. It is now January 2023 I have not seen an update to this thread. I need to find a solution. Please let me know my options. I am going to test the new firmware on my 2.2 and 3.0.
Thanks,
