When rain is detected, the skylight closes immediately. Rain-close logic should override all scheduled ventilation, voice control and normal app commands.

When humidity rises above the selected threshold, the skylight opens for a limited period. It closes after humidity returns to the target range or when rain is detected.

When outdoor conditions are suitable and indoor temperature remains high, the skylight opens for controlled night ventilation, then closes at the programmed time.

1. Rain sensor and emergency safety functions.
2. Opening limits and obstruction protection.
3. Manual wall switch or approved local control.
4. Smart-home automation rules.
5. Schedules, voice commands and remote app control.

Smart relays should only trigger the approved low-voltage or dry-contact control inputs. They should not bypass original travel limits, motor protection, rain sensing or emergency controls.

• Confirm roof structure, flashing system and electrical supply before installation.
• Retain the original actuator controller and approved safety circuits.
• Use the manufacturer gateway when official third-party smart-home support is required.
• For dry-contact integration, use an interlocked relay module to avoid simultaneous open and close commands.
• Locate the hub or signal repeater to ensure stable communication near the roof installation.
• Test rain-close, travel limits, manual control and automation scenes before handover.

• Inspect flashing, drainage channels, glass and perimeter gaskets at least once per year.
• Test rain sensors before wet seasons and clean them according to manufacturer instructions.
• Check actuator movement, control cables and power connections periodically.
• Review automation rules after any hub, app or firmware update.
• Keep an accessible wall-control or emergency operating method available.
• Document relay wiring and automation priorities for future service personnel.
