If you want two red dimmers in a 3 way config using associations and controlling bulbs it’s going to take a bit of work.
First you can either use built in associations or you can use a hub rule. I prefer the associations as it’s so much faster and not dependant on any hub.
If you use associations, you are going to have to make sure you change parameter 12 on both of the switches or else when you set up the association it will creat a loop that will either flood the mesh or the hub with events. Mine are set to local so it only sends the association command when locally triggered.
Next, you are going to have to understand the wiring. You will have to wire it so both switches will have no load but power is sent through to the bulbs. I know you can disable the internal relay but I didn’t like how that operated when I played with it.
Once that is done set up the associations from each switch and then you can not only control the lights from each switch but it will be fast and the state will be mirrored between the two switches.
I don’t have the bulbs but I think if they support associations to you might want to set it up so when they are turned on remotely they state is also triggered to the switch.
The only con that I have found is that if you control one switch via your hub that will not be reflected In the other switch so you either make a virtual switch for that or include all into the hub automations.
Like I said it’s not easy but it can be done and works well. I have had no issues with this setup. The only difference is I don’t control smart bulbs with them.
