I have a 3 way switch configuration with a dimmer at one location and on/off switch at the other location. The on/off switch looks like it's perfectly compatible with the HS210 with there being a common and neutral wire along with two travelers wires.
Here is a picture of the on/off switch:
The other switch location is a dimmable switch an older one with another dimmable switch next to it BUT the other one is not a 3 way switch because it only works from one location. It is a dimmer for our kitchen chandalier.
Here is a picture of the double switches with the switch on the far right being the switch that works with the other on/off switch.
Will the HS210 work in this configuration if I do not replace the other location dimmer switch right now?
NOTE: I'd like to replace the dimmer with an HS230 but just not this week.
