ECO Plugs integration not finding new devices with updated firmware

I have been using the ECO Plugs integration for some time with 2 DEWENWILS Pool Pump Timers and one went out. So after replacing, the new one was not discovered. The old ones had V 1.7.1 firmware, and the new one has V 2.3.0 but not sure if that has anything to do with it. It looks like the repo has not been touched in years, but wondering if anyone else has seen this issue, or knows of an easy fix.
