Hello everyone,

We just received a "good" tip from an acquaintance regarding electrical installations in a single-family house.

What do you think about motion sensors in the hallway/landing areas in the basement/ground floor/upper floor? Does that make sense?

--> Why?? ---> To save on double switches, since they would no longer be needed!

I generally don’t see any real disadvantages in not doing this. Have you already considered it or even planned it?

What could you potentially save? I don’t have a price for a double switch setup yet but will inquire about that soon.

So far, there are many (really good) tips, but all of them are clearly more expensive than simple switches.

The question is, how much does a two-way switch cost, and what do you actually save in the end if you have around 10 fewer two-way switches?

The question is about the additional cost, not the savings. Material-wise, 1 motion sensor is roughly equivalent to about 10 two-way switches (depending on series/manufacturer). Additionally, there is somewhat less installation work for the electrician.

But it’s not always just about money. That has already been mentioned.

A good value option is the orientation lights,
available as a 3-pack online for around 15€ (approx. $16), easy to place anywhere in the house without installation effort.

In the old house, my wife slipped down the stairs at night and tore her Achilles tendon. Since then, moving around in the dark has been strictly forbidden in our home.

That’s not entirely accurate... you have to consider everything involved. A light switch not only includes the insert, etc., but also a drilled wall box, which is then no longer needed. The additional wiring for two-way switches should not be underestimated either (in terms of cost).

Roughly speaking, in stairwells and passage areas, automatic sensors are always worthwhile, not only financially but especially because of the added convenience.
