How to repeat a TTS message over Google Home until turned oof

[Moonbase59 (Matthias C. Hormann)]

Peronally, I try to avoid NodeRed as much as possible—it’s another component that could introduce errors (though it can be helpful).

I’d suggest using an alert. Since many of us don’t seem to know how to make a TTS notifier (we don’t have built-ins), I did a little write-up yesterday:

How to notify using TTS — and much more

The situation In HA, we often use notify and notify groups to alert certain situations. We have a lot of notify integrations but none for TTS. In this How-To, you’ll learn how to Use variables and inputs to set a default TTS media player and TTS language. Create a long-lived token for REST API access. Make a notify.tts_google service, as an example for simple TTS notify services. Make a versatile notify.tts service for PicoTTS, using a script. Use our new notify.tts service in an automation. …

So now you have a TTS notify, using an alert seems very easy, because you can adjust repetitions, and cancel it. Good luck!

Then again, the smallest repetition would be a minute, so it might not help if you really want 2 seconds …
