System info: Core version is 2025.2.5, Supervisor is 2025.2.4 The OS is 14.2

Piper whisper and speech_to_phrase are all installed, their logs say
discovery has been notified.

Well I changed my hostname in /etc/hostname and added the new hostname and ip address to /etc/hosts. Now there is nothing in my logfile but discovery still doesn’t find piper, whisper or speech_to_phrase.

I have the same issue. Same version of HA, also with Piper and speech_to_phrase. Lets see if version 2025.03 makes a difference…

It didn’t for me I finally filed a bug report

I found a workaround. In the config of the addon (Whisper or Piper) at the bottom, you can expose it to the network using a defined port. I put the standard port there for whisper and piper. After a restart of the addon, you can then manually add them to Wyoming with the IP Adress of your Home Assistant Instance and the port you defined.

Worked for me. Thanks!
