HOMEKIT controlling Thermostat

Hello.

I started to use Homekit automations to control the heating via Netatmo Thermostat. In the IOS app I changed in the schedule menu to "Homekit" but the problem is that Netatmo App takes it as a manual change and keep that change max. 12 hours. 

For the time being the option is make another automation for 12 hours later but this is just a non normal way of doing.

Why you don't change that? When schedule is as per "Homekit" follow homekit instructions 100% ...
