Slow response on hm thermostat temperature change

Hi all,

When i try to change the temperature from my homematic thermostat with the webfront,
It keeps loading a long time on every change.

I also had this problem with some custom variables , i fixes them by adding a 50ms delay like was mentioned somewhere on this forum.

But on this build in variable , i can’t edit a script…so i can’t add a delay.

Thanks.
