I’m running Piper TTS on an external server and it seems like it only works through the Home Assistant UI, not via YAML.
I want to disable the cache so messages aren’t stored, but I can’t find any option in the UI to do this globally.
Am I wrong, or is there really no way to turn off caching for an external Piper server in the UI?
Any suggestions or workarounds would be appreciated!
Thanks!

okay so first.... why?
as for a work around... if you really wanted to i guess you could make an automation that triggers off the piper entity changing (meaning its been used) that calls tts.clear_cache.
although you will need to put in a short delay so the generated file can be used before you delete it

I want to avoid caching because I don’t want to fill up my eMMC or wear out the storage unnecessarily.

the file has to be written at least once anyway
so if anything your causing more wear by not caching because in cases of the same response its rewriting instead of using a cached version.
as for storage. i think it auto cleans itself on occasion to prevent that being an issue. but the files are pretty small anyway.
so when you generate tts with piper it calls piper which sends it a file which it stores. that file is then made accessible on the network from the HA server. and the link is send to the voice assistant.
a voice assistant does not stream directly from the piper server it streams from the HA server which gets the files to stream from piper.

i can disable the cache via configuration.yaml, but I can’t configure an external Piper server that way, only through the UI.

I believe that just means its generating a new file each time so if you have the same tts multiple times it will generate the file each time. the file is still there and written to the system
when a voice assistant plays tts it is streaming from a file that is on the home assistant server where that file is written and made accessible
what your trying to do is not a thing.
what are you running on with eMMC? a green i guess?
wild lion
yes
“The in-memory cache for fast responses to media players will be auto-cleaned after a short period.”
Sounds like with cache: False, TTS files are only kept in memory and not stored long-term on the filesystem.
marsh basin
in the case of wyoming for a voice pipeline i dont think there is an option to keep it only in memory

Ok, thanks for the help! Guess I’ll just have to live with the cache then, but really appreciate your support anyway
marsh basin
to be honest, unless you have like... 100 people constantly talking to it then its not going to be an issue
you could add a ssd to your green by usb and move your storage over to it if your really concerned...

Yeah, I’ll see, maybe I’m overreacting. Thanks for the help
