Coma as a decimal seperator

I call a Hubitat command from THR passing 3 parameters. One of them is 17.5 which is ONE parameter. Running THR on my pc it works because of the regional settings. But on my android phone it replaces the dot by a comma (17,5 instead of 17.5) so it is recognize as TWO parameters and causes the app to crash.

Is there a way to force a dot on my android dashboard ?
