DragonLAIR WiFi Controller

The DragonLAIR WiFi Roll-Off Roof Controller is an advanced, DC-powered system designed for managing observatory roofs. With a price point of $1,025, this controller provides a standalone solution for operating roofs without the need for a dedicated PC, integrating seamlessly with existing network setups. Users can connect the controller via Ethernet or its built-in WiFi, providing network redundancy in case of wired connection failures. The controller's web server enables remote roof operation through any smartphone or desktop web browser, while a hand controller is also available for manual roof movement. With up to 500W of output, the system can efficiently control roofs up to 16 feet in size, although the roof motor, motor mount, and other mechanical components are sold separately.

The DragonLAIR WiFi Controller operates with a 10-15V DC input, ensuring compatibility with most power supplies. It employs solid-state motor control chips and offers four ports for connecting retro-reflector safety sensors. These sensors prevent the roof from moving if no reflection is detected, which is useful for safeguarding against pinch points or ensuring that the roof only operates when the telescope is properly parked.

In terms of compatibility, the DragonLAIR integrates with several common amateur astronomy protocols, including ASCOM Alpaca and INDI. This makes the device compatible with popular imaging software, such as KStars on Linux and Mac, as well as N.I.N.A. and SGP on Windows. This feature allows users to fully automate their observatory operations, even while unattended. Additionally, when paired with external weather stations and software, the system can automatically close the roof and park mounts when adverse weather is detected. However, it is important to note that the controller does not directly integrate with weather stations or telescope mounts and relies on external software for such automation.

Safety is a top priority in the DragonLAIR system. Its four ports for retro-reflector safety sensors help prevent accidents by ensuring the roof does not move in unsafe conditions. The system also features an integrated state machine, which controls the roof's movements to ensure they occur only when safe. Users can further enhance this safety by connecting their weather stations and utilizing astronomy control software, like KStars or N.I.N.A., to automatically park telescope mounts and close the roof in case of bad weather.

The controller also includes an integrated buzzer that provides feedback during movement, and two limit switches are included to help regulate roof positioning. High-current Anderson PowerPole connectors and 45A rated connectors ensure the system can handle significant loads during operation. Additional technical specifications include a 10/100 Mbps Ethernet connection, firmware upgradability, and a Cortex-M0 133MHz dual-core processor.
