GrowPlugsV3 — grow tent and greenhouse controller

About the project

About the project

GrowPlugsV3 brings plant-growing equipment into one control system. It switches lighting, extraction, air circulation, humidification, heating and irrigation according to time and sensor readings.

Setup uses a local browser interface over 2.4 GHz Wi-Fi. Users can define daily and repeating schedules, temperature and humidity conditions, and events from water-level sensors or float switches. AND / OR conditions combine rules, while graph-based tables change setpoints over the growing cycle. No separate mobile app is required.

Supported inputs include DS18B20 and AM2302 sensors, dry contacts, and compatible digital and analog signals. The interface displays sensor and output states; configuration can be exported and imported as a file.

What’s inside

Six controlled 230 V sockets and seven sensor channels: five digital and two analog (0–3.3 V). Sensors receive 5 V power. The combined load across all outputs is limited to 10 A / 2300 W.
