Will these work well with the smartthings hub? (Security devices)

I would like to set up a small home security system and purchase z wave door sensors to work with the hub along with a z wave alarm and unlock/lock remote.
I’ve compiled the following list:

sensors http://www.amazon.com/Ecolink-Z-Wave-Window-Sensor-DWZWAVE2-ECO/dp/B00HPIYJWU/ref=sr_1_3?ie=UTF8&qid=1446750852&sr=8-3&keywords=z+wave+sensor
alarm http://www.amazon.com/Fortrezz-SSA2USR-Strobe-Wireless-Z-wave/dp/B006KH48VY/ref=sr_1_2?ie=UTF8&qid=1446752198&sr=8-2&keywords=z+wave+alarm
remote Securifi Key Fob AL-KFB01 on amazon (new users can only post 2 links)

Is this a good set up? Will they work well together? Anything else I need?

Yes on all 3. I don’t have the alarm but I have the other two. Had no problems with either. Though the key fob is not officially supported, so you will need to do some copying and pasting of code in the IDE.

It really depends on what you want to do, and how far apart each of the devices will be from the hub.

Thank you for the helpful reply!
Where can I find some info on programming the key fob with the smartthings hub?

They will all be on doors of the first floor of the house which is around 1700 sq ft and the hub will be located in the center of the home.

Here is the link the thread. You will need to go to GitHub and get the code and then create the device type and app per instructions.

You may need some repeating devices, depending on where you place your hub. The chart details the distances you should expect from a zwave device.
As all of the sensors you listed are battery powered, none of them will repeat/enhance your zwave network. The alarm might.

Perfect, thank you!!

Thank you, I didn’t realize I might need one. I will have to see once I have everything ready.

The individual devices should work with SmartThings, but that doesn’t necessarily mean you’re going to end up with the security system you envision. Before going too much further down this path I would read the security FAQ and follow the links that are in that topic as well.

SmartThings can work quite well as a notification/monitoring system for non-critical items. For example, I have it set up to let me know if the window was left open in the guestroom when rain is expected. But it doesn’t really compete head-to-head with a purpose built security system for most people even if you’re using the same devices. You’ll see the details in the example use cases in the links.
