Okay, installed the controller a couple weeks ago, luckily there was some slack above the ceiling making it pretty simply to wire everything up. The fan worked with the remote right away and after a bit of searching, I did a factory reset on the controller and it paired with me HE.
Even created a simply dashboard to control the light and fan. Using the remote caused the settings in HE and the dashboard to update.
Since then we've had two power outages, after the first one, I was able to use the wall switch to factory reset the controller and all was well again.
After the second outage, I wasn't able to successfully factory reset the controller. I've replace the ancient rotary switch with a toggle switch to make it easier to do a reset. When the power is on, the fan responds normally to the remote control. Multiple attempt to do a factory reset (off for 3 seconds, on for 3 seconds, repeat 5 times). The fan has been set to low and the lights to max and then everything is turned off via the remote before starting the reset process.
Any ideas.
