Hi,
I have seen multiple posts on the Internet regarding this picture for connecting a Shelly 1L with two switches:
Exactly what I need, and everybody says that this works, so who am I to disagree.
However, before I try this at home, I would like to understand the diagram and I fail to understand one point:
- Suppose the light is off, then their is no load on the line from Shelly 1L output O to the light.
- However, if there is no load on the blue line, how can Shelly 1L detect the position of he two switches on inputs SW1 or SW2 to turn the light on?
I would appreciated, if somebody could explain what I'm missing here.
May thanks,
Frank
