TTS for 1st gen nest hub failed

I've got hubitat set up for TTS and have 4 google minis that work great. I try to add my nest hub and first issue is the device name doesn't populate into hubitat correctly. I get "google-nest-hub on 192.16.1.XX" while the other devices populate their correct names "Bathroom speaker" etc.

when I try to send TTS alerts to the nest hub, I occasionally get a short chime, but most of the time nothing, and I never get the actual TTS alerts. The mini's just play whatever the TTS message is, no chime, nothing other than the message.

What should I try next? I tried Chromecast helper and it didnt seem to do anything, so I'm out of ideas.
