Your Niwa Grow Hub can only connect or disconnect devices from/to power, (On/Off control). So if the device you want to control has its own settings you can do as follows:
- Heaters: Set the temperature target to maximum possible.
- Coolers, fans, ACs: Set it to always ON and the temperature target to the minimum possible.
- Lamps: Set it to always ON and the desired spectrum and DIM level.
- Dehumidifiers: Set the relative humidity (rH) target to the minimum possible.
- Humidifiers: Set the relative humidity (rH) target to the maximum possible.
Finally, make sure that the settings of your devices are kept after disconnecting them from power and connecting them back.
