Why can't my controller connect to inline fans, clip-on fans, or other grow lights?

The controller only works with Spider Farmer devices that have an RJ port.Devices without RJ ports (like some fans or grow kits) are not supported. Please use compatible devices with RJ ports for smart control.

Why does my controller show “--” for many values?

The controller only measures temperature, humidity and VPD. For soil data you need a smart socket, for CO₂ and PPFD you need the SensorPro.

What are the conditions for installing the sensors in the individual systems?

It is not possible to install sensors of the same function type in one system. For example, you can install 1 soil sensor, 1 CO2 sensor, 1 GGS temperature and humidity sensor or GGS Sensor Pro in the same system.

How do I connect the GGS control unit to the lights?

Connect one end of an RJ12 cable to the “Up” port on the grow light dimmer box and the other end to the “Light” port on the (GGS Light & Fan Adapter).

Can the GGS control unit be connected to a GGS socket?

This is supported. Please note that the built-in controls of the socket are disabled when the two devices are connected. All functions are carried out via the GGS controller or the APP.
