Problem with tts and pronounce temperature

Hi everybody,

I’m still fairly new to HA. I am trying to broadcast the weather forecast via google tts on sonos. that works pretty well for me.
But I have the following problem:
if the temperature is eg 2.62 degrees then tts says “two point six too” instead of “two point sixty-two” and if the temperature is 3.72
he says “eight to four” instead of “three point seventy-two”.

and a second question: can I also convert the results of openweather into Dutch? Because now tts says “clear-night” instead of “open nacht” or “onbewolkte nacht”.

Is there a solution for that? If yes, I’d love to hear about it.

Thanks for every response.
