Hi, I'd like to power my outdoor lights in two different ways;

1. When my 240v outdoor wall light is powered on.
2. When I flick a (smart) switch. I want just the outdoor lights to turn on, not the wall light.

I believe that I can use a basic 240v relay which I can buy from eBay for $5. Is this the best option or is there an electronic version of this rather than a mechanical relay.
Attached is a basic diagram of how I will wire it and also a sample of the suggested relay.

Thanks.

 

Sounds like it could be done with a SPDT relay, whereby the NC contact would be inserted in the outdoor wall light circuit, the N.O. switches the outdoor lights?

 

So is there no other way to do this with any other electronic device other than a basic mechanical relay? If not I'll just stick with the relay to create isolation between the circuits.

What type of "smart switch" did you have in mind?

 

The challenge here is that the power switch for both the switched wall light and the supply to the garden light is one pair of wires controlled from the wall light switch. To separate them one scheme will be to use the same connection as present for the garden lights, but then to replace the bulb in the wall light with a "smart bulb" that is controlled by a phone app. The garden light can also be controlled by the module you mentioned, and the wall light switch will need to stay on at al times.
Easy to do but not cheap. Smart bulbs run about $35 in my area.

 

1. Replace the wall switch with a dual smart switch.
2. One switch controls the lamp.
3. One switch controls the garden lights.
Provides independent control of both circuits manually or with a smart phone

This scheme will require either additional mains voltage wires in the wall, OR two receivers for the signals from the smart switch that replaces the not-smart switch. So it is a more complex version of what I suggested already in post #5. Since the present single switch controls the only power feed for both the wall light and the garden light. The alternative is to add a second power feed for the garden light portion. That requires mains voltage wiring in a safe and reliable manner. (Local regulations undoubtedly apply.)

The dual smart switch is the same form factor as the existing wall switch. The required feed should already be there. Nothing more is necessary other than to remove/replace the wall switch and wire. The operational flexibility provided by this approach is well worth it.

The TS can use separate smart switches if desired. The physical location won’t be that important since the switches can be remotely controlled.

 

So I do not yet see how two independent items supplied by one set of conductors can be switched independent of one another, UNLESS there is an additional smart receiver at each load location. Can eetch explain how that can happen???

Respectfully MB, if it’s a dual switch, they can be wired with one feed or two feeds, it’s the users choice. Two separate smart switches can also be used instead. I don’t know what you don’t understand.

The switches on a dual smart switch can programmed to function together or independently. That’s the way they are designed. I use single units at various locations in my house except they are 120v.

 

My question is about how that second switch will be able to control a second set of wires to feed power to the garden lights, given that there is presently only one connection from that switch location to the outside light location.
OR, is it like I had already suggested, that TWO remote receive devices be added, one for the garden lights, and that the single feed from the switch box to the wall light be constantly powered.
Evidently some do not see that with only one set of conductors leaving that switch box, and that single pair providing the feed for both the wall light and the garden lights, that operation of those garden lights demands that the feed for the wall light be active.

Hi Lexdon,

The following schematic satisfies your requirements.



The relay K1 will switch on the garden light when the wall light is on.

The garden light can also be independently turned on, using the smart switch.

Nandu.

Perhaps the TS can describe the existing wiring?

Can you describe or draw the existing wiring configuration?
if the wall light and garden switch are in the same location, and can be remotely controlled, does that matter?

 

The implication that I got from the original post was that the existing outside wall light feed was also supplying the power for the garden lights. The implication then was that one switch was currently switching on both lights thru one single feed, and that this was not satisfactory because the TS wanted to be able to switch on ONLY the garden lights, and NOT the wall light.So the challenge was how to independently feed two different lights thru one single feed line.

The original post doesn't really describe the existing wiring.
Here is my suggestion


Doesn't really matter where the switched are located since they can be remotely (independently) controlled.

 

If both switches are in the existing switch box, then the drawing is not correct because the neutral connection for the garden light transformerwould not be the same neutral going to the wall light. And the ire from SW1 to the transformer is new, it somehow magicly appeared. Likewise the second line out wire magicly appeared inside the wall. That has been my point the lack of additional wires. Really, they do not just appear.

 

It seems seem that the OP is located N.A., If so, why is 240v being used for lighting?

I'll wait for a response from the TS.
