After months of tinkering, I finally managed to set up a system that automates my winter garden’s blinds based on temperature! 
Here’s how it works: I have a thermostat in the winter garden that monitors the temperature. When it exceeds the set target temperature, it automatically instructs the roller blind motor to extend the blinds. Conversely, when the temperature drops below the target (with some hysteresis), the blinds retract—though with a slight delay to prevent frequent adjustments.
This setup allows me to use the winter garden as a solar heater during transitional seasons without worrying about overheating when I’m away. The key was creating a direct link between the HmIP-WTH-1 thermostat and the HmIP-FROLL roller blind motor, as I believe critical functions should rely on direct connections.
The challenge was finding the right expert profile since there are no ready-made solutions for this specific setup. Through trial and error, I discovered the following configuration works perfectly:
plaintext
SHORT_COND_VALUE_XX: 200 represents the target temperature, while other values (0-255) correspond to specific temperatures.
SHORT_CT_XX and SHORT_JT_XX: Unfortunately, I’m still unclear why these settings work, but they seem to be crucial for the functionality.
SHORT_OFF_TIME: 31 hours means the blinds stay extended indefinitely until the temperature drops.
SHORT_ON_TIME: 3 minutes ensures the system waits before issuing the next command, preventing unnecessary movements.
On the second channel of the roller blind motor, I’ve integrated a rain and wind sensor, while the third channel uses a time profile for additional control. If anyone has insights into these settings or found this helpful, I’d love to hear from you!
