Hello, I primary use all insteon devices and run an ISY 994i. Can I add Z-Wave support to this device? If so, how? Silly questions, but not sure. I am looking to buy an August lock which requires z-wave.

Yes, you certainly can add a Z-Wave module to the ISY 994i. I did primarily for the same reason, to add Z-Wave locks. I chose Schlage as I was replacing existing non-automated Schlage locks and kept the same keys. I also liked the style.

Do you simply buy the module? No physical hardware to make the device find the z-wave devices? I believe with insteon I had a module that plugged into the wall or something.

 

Does the schlage lock work with a phone to lock/unlock doors? From what I read, it seems it's all pin driven?

One does not simply add only the zwave add on though - especially for locks.

 

As many of us found out - zwave requires at least 3 powered (non battery) devices to form an initial mesh. Locks don’t count, but the ISY does.

 

Most locks need a security enabled beam forming repeater device - like the Aeon Siren (although other devices are now reported to be as good). Avoid the original Aeon ‘repeater’ - it does not work with locks.

I added the module and it says it's missing the z-wave dongle?

There a physical daughter card that must be purchased and installed, Tools, Purchase Modules. Also see: https://wiki.universal-devices.com/index.php?title=Z-Wave:_Ordering/Assembly_Instructions

Any suggestions where to buy it? Link on that page goes to https://www.universal-devices.com/sales/?category=accessories but it doesn't list it.

Nevermind, found it on orchestratedhome.com

Worked like a charm. Got my first z-wave device added easily.
