Sundowner SD533 modification to control all 8 devices

Is it possible to modify the SD533 mini-controller to switch all 8 devices on and off at dusk? Out of the box it will only control the 4 units that are selected with the top slider switch.

I have looked for a schematic for the controller and the photocell PWB but have had no luck.

What I am trying to accomplish is to control my holiday lighting. I want them to all turn on a dusk and then off at bedtime. I thought that the appliance module would respond to "all lights on" but after buying everything I learned differently.

Now I am trying to make the best of what I have- (8) AM486 modules and this one SD533 controller.

I thought that if I could get the controller to switch all 8 units on at dusk, then I could simply send a "all units off" at bedtime.

As it is now, it looks like I my choices are:

  1. Manually turn each of the 8 devices on and then all-off later.

  1. Buy another SD533 controller and have each controller handle 4 units to turn on at dusk and then I use the all-off on both units at bedtime. Probably they both won't turn on within a short time of each other- this defeats the purpose.

  2. Buy some kind of programmable controller that I can write a macro that will turn on all units based upon dusk or a fixed time and then off at a fixed time.

It's obvious that I am brand new at this. I thought it would be easier.

BTW, the reason that I bought AM486 instead of light modules is that I use compact fluorescents everywhere in my house and I thought that in the non-holiday season I might find a use for the x-10 control of these lights. And now I read that CF and the AM486 may have issues.....

Advice anyone?

TIA, Rich

X-10 is unloading their stock of RCA-branded CM11A computer interfaces for $10 + $6 S&H. One of these can be easily programmed with timers and macros to handle the Dusk-relative lighting. See:

Well, duh, and I thought I was a sort-of smart guy. Gotta think outside the box more.

Setting all the units to the same HC should work perfectly.

And I ordered a Home automation kit as well for other applications.

Thank you for your GREAT suggestions!!

The only think to be careful of is where you place the sundowner, and to adjust it's trigger point. I basically have mine on a window sill, pointed outside, so it won't be effected by inside lighting.
