I want to install a Sonoff ZBMINIR2 and I am confused about the wiring instruction. I thought maybe someone here already installed such a smart switch and may help me
My hallway has four push button lightswitches. I think I found the one I need to get the switch behind, as this one has 4 cable, the other ones only three.
The switch has labels on each side. UF where the brown cables are and N where the grey cables are.
Do I wire both grey cables up the N ports of the ZBMINIR2? How exactly should the brown ones be wired?
How hope my questions are not too stupid. I want to be cautious, as this is not something I do every day.
Be careful here. I think your challenge here is not with zbminir2, but to understanding your existing wiring setup on this specific circuit.
Are the 4 push button switches all controlling the same set of lightbulb(s)? Are they all on/off?
You will want to first figure out the wiring diagram including the lightbulbs, the 4 switches, and were the power coming from. Continuity tests, power tests, which wire going where doing what, etc.
I would not assume or trust any label nor the color of the wires. You will want to know that your wiring diagram being accurate.
A quick googling is telling me there are at least 2 ways for 4 switches to control 1 light.
... and I'm sure there are variations to each of those methods. And then there are even more methods for different use cases.
Like I said, your main challenge is to figure out the wiring diagram.
And after you have a good diagram for your existing setup, wiring the zbminir2 would become fairly straightforward
zbminir2 will have to be installed at the switch location that is closest to your lights. In both of the 2 diagrams above, for example, the location would be at the 1st one from the right hand side.
and then you will want to make sure you have neutral wires in your switch box location - likely in blue but please verify your blue wire is indeed neutral.
If all of the above becomes too complex - which is understandable because 4-switches-for-1-set-of-lights setup is relatively rare and complex in itself - that would be your cue to hire an electrician.
