We are installing home automation systems, and we have serious problems with electricians. Short: they are stupid and lazy. So, we have to do something.
There're some stories:
We have a spreadsheet with a numbered list of all the wallets, lamps, switches, and also a layout map of the house, all wallets/lamps/buttons/etc. signed on it with these ID numbers. With this list in his hand, our electrician just marked all wires with his own words instead of numbers, e.g. "sleeping room lamp switch". He has made no checklist at all.
We're working at the rack, wiring relays. There are cca. 200 wires coming from the rooms for input/outputs installed by electrician, but after a while we found that about 50 wires are missing, there are plenty of relays left empty. We call electrician, he says: "I have had no more space for wires".
(Not my story.) We mark all swith places on the wall with small sticky papers, writing ID numbers on it. Checking wires, it appears that there is a wire numbered "4" at the place "14". Electrician says "oh, I did not see the '1' before the '4'...".
And so on. Electricians don't do any documentation. The pen and paper is missing from electricians' toolbox.
We're enough. Legendary hard times arrives for electricians. We will don't pay if they don't do their job immaculate (we will ask customers to do so). Sorry, guys.
So, what we need is a simple, easy-to-understand graphical markup system which we can push into the hands of the electrician, and say: that's the job, brother, do it, no more, no else, no less, otherwise you will be surprised at payment.
Is there any standard for it? We should draw it into the layout plan. We should put separate rooms to separate pages, if it helps. Any ideas are welcome, e.g. "make two drawings, one for wallets and another for lamps", "use only prime numbers for IDs", "don't draw, use detailed textual instruction list with checkboxes", "ask him to sign that he understands the plan and the conditions" etc.
The drawing system should contain the following item types:
- shutter pushbutton (two-way, 3 wires: common + up/dn),
- wallet 220V,
- IR/move sensor,
- shutter motor (3 wires),
- lamp 220V,
- wallet 220V,
- CAT5 ethernet cable (both for computer network and buttons),
- other power wire (e.g. 12V),
(I will update the question if you have other important requirements I forgot.)
