VIVOSUN GrowHub E42A+ Smart Environmental Controller
Bring compatible grow lights, fans and other growing equipment together with the GrowHub E42A+. Monitor temperature, humidity and VPD, and customise automation with timer, cycle and schedule controls from the colour LCD or the VIVOSUN App.
About This Item
- Unified grow control: Manage up to six compatible devices through one GrowHub E42A+ controller.
- Environmental monitoring: Track temperature, humidity and VPD to guide environmental settings for different growth stages.
- Remote app access: Use a 2.4 GHz Wi-Fi connection and the VIVOSUN App to monitor and manage your compatible equipment remotely.
- Customised automation: Set timing, cycles and schedules, with supported spectrum, intensity, on/off and airflow adjustments depending on connected equipment.
- Clear local interface: The colour LCD offers a 480 × 272 display and straightforward on-unit navigation.
- Optional expanded sensing: The separate VIVOSUN 4-in-1 sensor adds CO₂ and light ON/OFF detection. Do not confuse E42A+ with E42: the 4-in-1 sensor is explicitly not compatible with E42.
