All CeleryScript Nodes

This list is split into three categories.

RPC Nodes

Nodes that control Farmbot's state, but don't don't command a real world side effect. This includes:

• updating configuration data.
• syncing.
• starting/stopping a process of some sort.
• rebooting

Command Nodes

Nodes that physically do something. This includes:

• moving the gantry.
• writing or reading a GPIO.
