Ok, now I got ya! I kept thinking one central command center type thing. Yes this simplifies thing as Torben said. Now were rolling. But now I am back to, if the service personel have to go look for lights being on, why not use the little clean my room cards on the doorknob...

Sorry, not trying to be a pain

It would be easier if we could be in a meeting room to hash all this out..Oh well

I think the control unit may be fixed near the bed. the reciever will be fixed to the outside door.

 

So, hey yo Adriaan...

Is this what your kinda envisioning? See pics.

From what I understand, that's what Adrian wants, except without the yellow LED. I think the "Clear" state is just to ensure that neither the green nor the red LEDs are lit.

It seems as though we may now be getting on the same page which should allow things to go smoother Now we need the RX interface to figure out how to turn on the outside LEDS ...

Yup.

If anybody is interested I put a short video of my three-relay monstrosity up on Youtube ( http://www.youtube.com/watch?v=w3E-c3mAOnc ). Caveats are as in my earlier posting on it. Again, I still don't recommend it as a solution, I just wanted to see if I could solve the problem using no timers or µcs. This does the trick but can still be fooled by quick switching. However, the errors can all be compensated for at the receiving (display) end if necessary.

I've also attached a map of what LED means what.

Wow, I thought I was cool with my 3D model. But video and everything... Gotta love that From the way we now understand the setup, I do not see false triggers as being an issue as there is no real alarm sent. It is only the final state that matters. That is what I am thinking...
Oh yeah, quit bitting your nails...lol

Well, as it looks the whole point for that circuit is moot anyway.

Biting my nails?

yes, somehow like that, nice picture

 

I am not so sure the picture is nice. The pastel purple walls just seem to clash with the leopard print on the bedspread

My bad humor again

Hey, nice testing~
Have you posted that circuit before?

what is the right two LEDs for?

 

That circuit is the one in the schematic I posted earlier, yes, just with a couple of modifications to make it obvious what it's doing in testing.

Here is a better explanation of the LEDs (as labelled in the photograph, from left to right):

"Do not disturb pulse indicator": This LED wouldn't be in the final circuit; it's just there to flash when the relay contacts for the Do Not Disturb signal are briefly closed.

"Do not disturb": Indicates that the switch is in the Do Not Disturb position.

"Please clean": Indicates that the switch is in the Please Clan position.

"Please clean pulse indicator": This LED wouldn't be in the final circuit; it's just there to flash when the relay contacts for the Please Clean signal are briefly closed.

"Clean pulse indicator": This also wouldn't be in the final circuit; it's just there to flash when the relay contacts for the Clear are briefly closed.
