Vivosun GrowHub A22 is a Wi‑Fi smart outlet controller for small grow tents that automates devices using a plug‑in temperature and humidity probe. The A22 (model GH‑A22S) provides two ETL‑certified AC outlets (total 15 A, 1800 W resistive) plus two 5 V USB ports and works with the Vivosun App over 2.4 GHz Wi‑Fi or locally when offline. Users can schedule timers or trigger on/off control by measured temperature or humidity, and integrate the unit into Vivosun Grow Recipes. Technical details include sensor accuracy of ±0.9 °F and ±5% RH, a 3 m probe lead, and operating ranges of 32–140 °F and 35–85% RH. Typical uses include switching lights, fans, heat mats, and humidifiers based on real‑time readings.
