Finished my install and very pleased with the system! I did run into some minor problems with the prior ADT install regarding improperly labeled wires, but Konnected makes it really easy to work out those bugs and test your connections since you can carry your phone with you while testing various contacts.
My AT&T wireless access point gave me problems with the discovery of modules, so I did have the unexpected expense of adding a separate router in bridge mode, but that is a plus in the end as the signal is much stronger, I created a channel specifically for Konnected and I can use the Netgear 4G LTE cellular modem for backup internet access.
You can see in the pictures that I chose to mount everything on a board instead of an enclosure. I had read somewhere that the metal enclosures can hinder wireless performance and since all of my equipment is under the landing of the stairs, it's pretty well tamper resistant as it is. I chose the Kindle Fire 7 tablets which were very inexpensive back around the holidays and I followed a YouTube tutorial to install Google Play Store. Each tablet (one upstairs, one downstairs) uses the old wiring for power which is distributed from the main panel. All of my zones and routines are nicely displayed using ActionTiles which is locked down with Fully Kiosk. I was using DAKboard as my screen saver but two minor issues arose. First, in order to dim the screen in the master bedroom at night, I setup a routine in Fully Kiosk for that to happen at 10pm and end at 6am. The problem was that Action Tiles was inaccessible during these hours as the frame (painted to match my ecobee thermostats!) holding the tablets does not provide access to the buttons. In the morning the screen would reappear locked. This simply required an upward sweep to put everything back in order, but it was aggravating. Ultimately, I removed DAKboard and I just use a black screen on a 30 second timeout via Fully Kiosk. Tap the screen and there's my ActionTiles panel! Also, the colorful screen savers used a fair amount of power and I ended up changing my adapter from 5V 2A to 5V 3A in order to keep the tablets charged to 100%. I also added an Amazon Fire Phone at the entrance from my garage which works really well with the Fully Kiosk motion sensor. This only displays three items, alarm state, Home routine and siren / strobe. I did this because I've found presence sensors to be either a little slow to respond or sporadic when batteries get low. I had very poor success using our phones as presence sensors. At a glance, you can see if the system has disarmed and if not, run the Home routine. In the event the alarm is accidentally tripped, the siren / strobe option allows for a quick fix. Each of these is PIN protected. For some odd reason, this phone will not charge via the existing wiring so I will probably install a recessed outlet and mount the phone over the top of it.
One final change I plan to make is replacing my living room motion sensor with my Arlo camera, again using the existing wiring for power. I could not be more pleased with this system and I hope this little write-up is helpful for others just starting out.
