Question 1

I have a hardwired traditional 3 way setup with 2 locations, will this work?

Accepted Answer

Thanks for the question.  You replace the complete setup for that fixture.  To explain further: the D26HD will be installed in the primary location (controlling the fixture).  All other connected locations controlling this same fixture will require a DD00R (wired option) or DAWDC (wireless option) in order to control.  Cannot use existing standarddevices as these devices also have intelligence to keep track of light status.

Question 2

Does the 2nd generation plug still connect to 5gh?

Accepted Answer

No, it does not.  2nd Gen devices only work with 2.4 GHz networks.

Question 3

Difference between Gen 1 and Gen 2?

Accepted Answer

Thanks for the question!  Decora Smart Wi-Fi 2nd Gen devices Work with HomeKit/Siri, Hey Google, Amazon Alexa, and more. The new devices are compatible with 2.4GHz Wi-Fi networks, include wire leads and a reduced product depth for easy install, feature a streamlined app setup process, and work with the new wireless Anywhere Companion Switch (DAWSC) for wire free 3-way control.  Any other questions - please reach out via email, phone, chat, or app and we'll be happy to help.

Yes, Decora Smart Wi-Fi 2nd Gen works seamlessly alongside all existing Decora Smart Wi-Fi products.  While Wi-Fi 2nd Gen devices offer additional functionality – they can be grouped together and included in scenes, activities, and schedules.
Do Anywhere Companions directly control a load?
No, Anywhere Companions wirelessly pair to a primary Wi-Fi 2nd Gen Device which controls the load directly.
What is the wireless range of the Anywhere Companions?
Typical recommendation for installs is within 50-feet of the primary Wi-Fi 2nd Gen device
Can I pair Anywhere Companions with a Decora Smart Wi-Fi 1st Gen or HomeKit Dimmer or Switch?
No, Anywhere Companions are only compatible with Wi-Fi 2nd Gen devices.

Question 4

Can this be used in a 4 way wired setup?

Accepted Answer

Absolutely, use the D26HD and then 2x DD00R (if wish to do hardwire) or 2x DAWDC (for wire-free multi-location).
