Thank you both for the super helpful replies, it will teach me to just bash out a question whilst watching Eastenders without giving it enough thought. There is only so much Sharon Watts a man can bear but I digress…
So below is a picture of the current switch controlling multiple lights:
From left to right, the switches control:
Far left - On/off for just the lights in the porch. They are currently just spotlights within the porch ceiling, further picture below…
Middle - On/off for just an interior light inside the hall, not planning on making that smart just yet but if it’s easier to do then may well do so…
Far right - 2-way switch controlling the light at the top of the stairs. The light at the top of the stairs can also be controlled by a single switch outside one of the bedrooms. This might be trickier to convert as I guess I would have to do the same upstairs?
The house is a child of the 70’s so the wiring is slightly older than a modern home, I’ve taken a shot of the inside of the switch below:
These are the porch lights (there are actually three of them) as they currently stand, just spotlights. I haven’t removed the ceiling but I would imagine there is a transformer buried away up there but they could also be 240v lights. I don’t know without ripping out the ceiling (which is also planned)
Moving outside, we do have a crappy old mains spotlight that you can see in the shot below. I’m planning on replacing this with a smart floodlight instead so I’m now thinking maybe separating out these two ideas. Have the floodlight come on if the movement is detected around my car and have a second sensor for switching on the porch lights?
The pictures below are of the front of the house and a close up of the eaves over the front door. I’m also pondering an exterior light in the porch eaves but outside as we’re always struggling to see the lock when it’s dark…
So my ultimate goals here would be the following:
- Someone approaches the front door when it’s dark then the interior porch lights come on and a single spot under the eaves so we can see the door lock easily
- Retain the ability to switch the porch lights on and off (interior and exterior) via a “normal” switch. Thinking about the mother in law who is a technophobe.
- I work for a company that supplies a home smart alarm that has IFTTT and Smartthings integrations (I’m not going to say who they are as I don’t do name dropping) so maybe the floodlight should only come on when the system is armed and motion is detected. We have an IFTTT applet that can support that.
Hopefully, this is all helps and certainly sounds possible but I’d like to get this right as smart hardware is more expensive than a £4 light switch from B&Q.
Thanks in advance
