Ra Grow Light Controller

Ra is a dedicated grow light controller that automates spectrum and dimming for your garden. It runs lighting recipes on-device, so your lights follow a consistent day/night cycle even without an internet connection, with full scheduling, presets, and manual control from the web app. Powered by a standard 5V USB-C charger.

Choose your version:

• Ra (0-10V): outputs a 0-10V analog dimming signal across 4 independent channels for compatible LED fixtures, with a plug-and-play RJ connector.
• Ra (RS-485): controls multi-channel digital fixtures (such as the Solark family) over RS-485, with per-channel spectrum control, a live power-share view, and on-device temperature safety.

Key Features

• On-device lighting recipes that run even when offline
• Cloud scheduling, light presets, and manual control through the web app
• Custom presets let you name channels, assign colors, and build your own recipes
• 5V USB-C power with simple Wi-Fi setup via captive portal

Choose the RS-485 + Temperature Sensor option to include a wired probe for automatic temperature safety, which dims or shuts off your lights when the grow space gets too hot, even if your internet connection is down.
