Blue Series 2-1 - How to configure 3 Way with 2 blue smart switches

Does anyone know how to configure this in Home Assistant?
Basically binding the switches together to sync: on, off, dim and led bar?.
@Eric_Inovelli @EricM_Inovelli do you guys happen to have any info on this?

Longer version…
I started by following the instructions:

a) Changed my 3 way wiring - basically it is no longer 3 way, it is now a single pole switch controlling the light on one side and a switch without load on the other).
b) Based on the instructions the next step would be to bind both switches.

And that is where it get’s tricky… the manual has a place holder for this instruction which was never updated. Also somewhere in the instructions there is a video where it reads switch to switch but it is actually switch to bulb.

Already posted on a few other threads with similar subject and email support but so far no luck.
Meanwhile all my 3 ways are broken and kids afraid of leaving their room at night because they will have to walk in the dark until the other and of the hallway … :face_with_diagonal_mouth:

Take a look at these HowTo’s. Switch to switch is at the bottom.



At least for ZHA, the switch to switch How-to instructions are just a copy of binding a switch to a bulb, so they’re somewhat less than ideal. Plus HA has changed the UI a bit. I assume the instructions are just unfinished. (@Eric_Inovelli: Any ETA on having instructions?)

FWIW, Here’s what I did in ZHA:

On the device page for the switch, click the three dots in the Device Info section, and choose Manage Zigbee Device.

Select the Bindings tab.

Choose the other switch under Bindable Devices and click Bind.

(At least for me, the spinner never stopped spinning, but it seemed to work.)

You’ll then need to go to the device page for the other switch and repeat the steps to bind the other way.


Exactly, in this particular document it literally says:

NOTE: Need to update these instructions. It is a copy/paste of the above.

In some other document it will say something like “Place holder, will update tonight” and things like that.

That worked. Thank you.
I have tried it before but only from switch “A” to “B”, it didn’t occur to me I have to do it the other way as well.


@Eric_Inovelli @Bry FYI, think zigbee binding instructions for switch to switch are missing for smartthings. Can You Share them please? Ty

Give me a couple days and I will write something up. Ping me if I forget. I’ve added it to my calendar though. Problem is finding my test setup that was in my old office so that I can figure it out and I need to setup SmartThings in the new office.

@EricM_Inovelli – what endpoint do we use for Inovelli switch to switch bindings?


TY. I think I’ve figured it out, though what I am not sure about is:

  1. Should swithes we bound both ways, or only the switch that is not connected to the load should be bound to the switch that is physically controlling the load?
  2. Endpoint code as you mentioned.
  3. Do settings and scenes need to be duplicated for each device, or will the zigbee binding cause settings and actions to be shared accross both devices?

Yes bind both ways or use a group. Here is a group setup with 2x blues, 1x zigbee tuya bulb, and 1x sengled buld

Now bind each blue to the group (blue1 and blue2)

I think if you look at my screenshots it should answer your questions. Basically EP 2 is used to send states and EP 1 receives updates

My habit is to set all automations/actions to act on the load switch. The other switch should mirror any updates.

Should be duplicated if you want equal performance (like ramp times, etc.). Scenes will not be shared.

TY. I am using Smarthings though so I’m not sure how I can replicate this. Hopefully Eric is able to publish instructions soon.

@Eric_Inovelli Pinging you. TY

Yep, in SmartThings you will bind each device to the other.

A → B
B → A

@sdbigio – just shot you an email – but here’s the gist of it (copy/paste from the email):

Basically, you’re going to want to follow the directions here: How To's | Setup Zigbee Binding - SmartThings. Prior to that, get the Zigbee ID’s of each Inovelli switch.

In those instructions above, click on your first Inovelli switch and go into the settings (Step 6). Input one (1) where it says, “Bind/Unbind Device Endpoint” and then put your second Inovelli switch Zigbee ID where it says, “Bind Device”.

Then do the same thing but in reverse for your second switch (ie: Endpoint 1 and Switch 1’s Zigbee ID).

I’m hoping to get caught up by the end of the week and I promise I’m trying as hard as I can to put out all these fires. This was on my checklist for you, just a few other fires above yours… maybe one day I’ll have free time!

Keep me posted on if this works.
