Software for wiring diagram designer

[MrTeaIOT]

I am looking for free software that I can design the wiring diagram for my house lights diagram from power supply to all the pixels distributions.  Anyone know a good one that is free.  Online version is okay too.  I have not found on that is free and without subscription.

I've seen plenty of them done with Word but if you really want to go the whole hog you could go with Sketchup https://www.sketchup.com/.

It looks way complicated that want I need.  I just need to be able to show my wiring diagram before I actual install it on the board.  I plan to centralize everything.  Like to draw out a plan from 120v outlet to multiple power supplies, block of fuses, amp meters, F16v3 board, FPP pi3, switches and etcs.  I found this site http://www.schematics.com but little complicate too.  As long as free online is fine.

Sounds like pencil, graph paper, ruler and an erase will be the best.

I've used Excel for this - just size the rows and columns to make "graph paper" size grids, then use shapes for controllers, props, etc, then you can draw lines along the grid, or use the line shape.

How about Open Office Draw?
