Hi all, I’m completely new to IoT and Haas and would like to build my own home security system but I do have a bunch questions 
and would really appreciate some advice from the Haas community.
I have a couple of Raspberry Pi 3’s and an Asus Tinkerboard I can re-purpose but am not sure how best to integrate all the services I need. I’ve also been looking at the Samsung SmartThings hub and was wondering if I need or would gain any advantage of including one in the setup.
Random questions
Should I standardise on z-wave/Zigbee or Xbee or support all three
If I use the PI is what is the best device to provide the above
Must have
- Monitor ± 8 motion sensors (range 7 - 9m)
- Manage the motion sensors as individual units or create zones
- Include a panic-button option
- Manually or event based - turn on security lights (10 - 12 LED flood lights)
- Trigger events (i.e. alarm & or lights & or notifications) based on various criteria time or some other…
- Control and receive notifications via mobile phone and not rely on a static control panel.
- Send alarm events to security company
- We have frequent power failures, so I don’t want to rely on 802.11 wifi for the motion sensors but assume battery backup for the Pi
