I moved recently to a ZWA-2 and after about an hour existing devices mostly repopulated, a few were stubborn however and I noticed that I cannot discover any new devices. I tried some ThirdReality Plugs and a Aquara Motion Sensor and while they are in pairing mode they are never detected by HA. I've tried restarting HA as well. In the logs I don't see anything related to discovery just existing devices.

Neither of those sound like Z-Wave devices
They sound like Zigbee
i.e. the ZWA-2 is a Z-Wave controller and won't support Zigbee devices
Sorry that was my bad, was trying to look up model names that are very similar sounding. ZBT-2. I couldn't figure it out, I ended up removing the whole integration and adding back every single device over the past few days.
