Step 3 - Configure wifi, database, and which sensors you want to use below, and hit "SAVE".
Step 4 - Plug in any sensors you want to use according to the wiring diagrams below.
Step 5 - That's it. You can now disconnect the NodeMCU and move it to the greenhouse.

Step 4 - Plug in Sensors
At this point, if you've saved your settings to the NodeMCU and everything went through without any errors,
you can unplug the NodeMCU from your computer, plug in any sensors,...
Step 5 - Deploy
...and bring it to the growhouse of your choice. The NodeMCU can be powered through USB
(including from a computer, external power adapter, or battery) and by connecting the GND,
VIN pins to ground and a 5V or 12V power supply respectively.
