Hi, I am trying to install a 3 way switch but my current switch has 2 reds, 2 blacks, neutral and ground. The new switch only has 5 wires (live, 2 travelers, ground and neutral). So how would I wire this into it? Since this is a smart switch, would I combine the live and load? It may help to note there are 4 switches, I have already identified the start and end switches. The one described above is in the middle. The start and end switch only have 2 blacks and 1 red, but connected to a 3 pole switch. Pictures are below.

You are trying to replace a 4w switch with a 3w. You are going to lose functionality.

You need to follow the directions for the smart switch install. All them that I have seen can not go in the four way position. They have to go in one of the three way positions.

I appreciate the super quick replies, but reviews of the switch has people saying that it can be installed in a 4way but requires a different install:

I follow this direction.

This 3-way light switch can be used both on 3-way and 4-way.

One way to interpret that statement is that the smart switch can be installed in a 4-way circuit, but left unsaid is that it must replace one of the 3 way switches. I don't see how it could possibly replace the 4-way switch.

Do you have the model of the switch?

It's the MSS550X


I already reached out to Meross but haven't heard back, I just figured someone familiar with Electrical would know something about this and be able to help.

My point was to contact the tech support for the device. They will tell you how if it is possible.

According to their website this can only be used as a 3 way.

I'll wait to see what they say then and post here if it helps so it will help others if they search.


I just find it odd that no one makes a true 4-way smart switch.

Every 4 way circuit will have two 3-way switches. Far more 3-way circuits exist than 4-way, so 4-way switch product volume is smaller.

Given the smaller volumes, three is no need for a smart 4-way switch when a smart 3-way can do the job.
