Heater and backup fan functions

Heater and fan control is now added to the board. The fan starts at set temp and continues until a lower set temp i reached (30 minutes minimum).

The heater works in a similar fashion but it has two set temps depending on if light is detected or not. This gives us an optimal temp for night and one for day.

There are also four extra relays that can be used manually for whatever you want. One of those is shared with the heater.


Another neat feature is that the display can now turn itself off when dark is detected. This way it will not disturb any sleeping plants.


This is the “soil kit” without water sensors or ph-probes and so on.
