Seeing the little crafting that there is in the different electronic sections, it is perhaps the most wasted to level at level 3 to use generators seems an excuse for their existence to be relevant I propose the following…
Sprinkler head and hoses: Farming is a heavy and tedious task get a few sprinklers to connect you to a well or collector program it with a timer so that it always activates at the same time and Bam! You will not have to be so aware of the vegetables.
Motion Sensor and Remote Controller: Getting out of the car to open the door at your base, leaving your car and closing it again could be somewhat annoying, disassemble a garage door and program it with a remote controller to close and open without getting out of your vehicle or better to use a motion sensor so that automatically when you pass in front it opens.
Traps: maybe a crafting to tramp?
