Ra Grow Light Controller

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

One controller, up to four zones. Ra has four channels: run one zone of 4-channel spectrum lights, two zones of 2-channel lights, or four zones of single-channel lights, each on its own independent schedule. Connect the first light with one cable and daisy-chain the rest.

Choose your version:

• Ra (0-10V): outputs a 0-10V analog dimming signal across 4 independent channels for compatible LED fixtures via an RJ12 connector.
• Ra (RS-485): controls multi-channel digital fixtures over RS-485, with per-channel spectrum control, a live power view, and on-device temperature safety.

Key Features

• On-device lighting recipes that keep running even when the internet goes down
• 24-hour schedules with as many periods as you want, with instant, linear, or natural sunrise and sunset transitions
• Up to four lighting zones on independent schedules from one controller
• Cloud scheduling, light presets, and manual control from your phone or computer
• 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.
