The existing actuator and controller remain responsible for the skylight’s motion, opening limits and original safety functions. The retrofit system sends commands to the approved control input instead of switching the motor directly.

The gateway or relay module acts as a command layer. It can receive app requests, schedules or sensor data, then issue approved open and close commands while the original controller continues to manage travel and protection.

Rain and emergency safety logic should operate locally whenever possible, so automatic closure can still work even if Wi‑Fi, cloud services or remote access are unavailable.

1. Review the existing skylight actuator, controller, switch and wiring diagram.
2. Confirm available integration ports, voltage requirements and approved control method.
3. Select gateway, relay, rain sensor, climate sensor and blind-control options.
4. Prepare wiring harnesses, low-voltage control connections and mounting accessories.
5. Install the module without bypassing original safety circuits or travel limits.
6. Pair the smart controller with the selected hub, application or local network.
7. Test rain close, emergency stop, manual control, automation rules and final sealing condition.

• Inspect the existing skylight, roof flashing, actuator and controller before retrofit work.
• Confirm the control interface from the original wiring documentation.
• Use a qualified electrician for relay, power supply and control wiring.
• Install rain sensors where they receive actual weather exposure and can be serviced.
• Use interlocked control outputs so open and close commands cannot operate simultaneously.
• Document all wiring, relay channels, automation priorities and emergency procedures.

• Test rain closure before wet seasons and after any controller update.
• Inspect roof flashing, drainage channels and seals independently of the smart system.
• Check actuator movement, relay operation and local wall switch function regularly.
• Review automation schedules after seasonal changes.
• Replace batteries in wireless sensors and remotes as required.
• Retain manual emergency operating instructions near the local control point.
