ICal Integration into Homematic for Automation

I'm looking for a seasoned expert to help integrate the ICal calendar from my holiday apartment software into Homematic. The primary goal of this integration is to automate heater control, specifically, the Homematic IP Wall Thermostat utilized in the apartment.

This project aims to have the heaters switched on ahead of guests' arrivals and lowered after their departure, with timings based specifically on check-in and check-out periods.

Skills & Experience Required:

- Profound understanding of the ICal calendar and Homematic IP Wall Thermostat.
- Proven experience in integrating ICal with various platforms.
- Strong coding and automation capabilities.
- Knowledge of temperature management systems and their operations.

The operation's effectiveness will be gauged by heater control smoothness when catering to guest arrivals and departures.
