Tuya TRV603-WZ - Window connection?

[Sailing74]

Hi, I have a TRV603-WZ (from matosio) here, appears to work generally well with z2m. The one thing that I can't figure out is out to tell the valve that the window is open. "Window" is not writable, and triggering window_detection doesn't appear to trigger any action for the valve. Any hint for how I could briefly interrupt heating because of an open window (other than directly setting current_heating_setpoint, which begs the question what window_detection and window are there for)?

Thanks!
