Apologies in advance if this is an obvious question, but I am a little confused. I’m looking to make some changes in our kitchen, we’ll have a few 3-way switches to control lights and I’m planning (already ordered) to use the new Blue Series switches to control them. I have SmartThings and like Zigbee.
To setup a 3-way do i HAVE to use AUX switches or can I use 2 blue series switches? I know there is a price difference, I’m trying to understand how many I should or I need to buy of either to avoid being last minute with too few switches of one type. For simplicity I was planning to buy all Blue Series. I admit I am tempted by the cheaper price of the AUX too.
It might help to think of an aux switch as a dumb switch that’s wired a bit differently. There’s no smarts inside it, it’s just designed to allow dimming at both ends and give you the ability to multi-tap.
The smart switch will detect whatever it’s connected to (aux or dumb).
If the smart switch is connected to a traditional dumb switch (ie: the $2 ones you buy at Lowe’s), it can detect if that switch is on or off.
If the smart switch is connected to an aux switch, it can detect paddle presses (up, down, hold) and multi-taps.
So, the only thing you are pairing to your hub is the smart switch.
That may be a bit confusing. You do NOT pair the Aux switch with the HUB. The Aux switch must be wired to a Smart SWITCH and then you change a setting on the Smart SWITCH to tell it there is an Aux Switch connected to it.
The HUB doesn’t know anything about the Aux switch.
