GrowHub E25 Controller

The Vivosun GrowHub E25 is a compact Wi‑Fi controller that adds app‑based automation to Vivosun Smart Grow System devices. Insert the E25 into the Type‑C port of compatible hardware — such as AeroLight grow lights, AeroZesh inline fans, and AeroWave E circulation fans — to enable remote scheduling, dimming, and speed control via the Vivosun App. It can run independently or act as an expansion port with a GrowHub E42/E42A so devices can share or follow separate recipes. One E25 directly controls one device; AeroLight fixtures can be daisy‑chained via RJ45 for group light control. Key specs include model GH‑E25, 12 V input, 3 W power, 2.4 GHz Wi‑Fi, and an operating range of 32–140°F (35–85% RH). Pairing with AeroLab THB1S adds temperature/humidity sensing.
