@bline22 I guess i will be going against the grain. I would recommend from my experience the kwikset locks. I use the kwikset 912 lever lock and the battery life has been phenomenal so far. I have the kwikset autolock after being open for 30 seconds. I did some research on the schlage deadbolts and lever locks and it seems sometime they have trouble relaying the state back to the smart things app. with my kwikset set lock i get instant status updates when locked and unlocked, as well as being able to know what code is used to unlock the door and even when my lock is jammed because door hasn't been shut all the way i can see it on the mobile app saying that lock is jammed. Now a big key factor when looking for new household locks is what keyway you have, because if you have currently kwikset, or yale keyway they may not always mate up with schlage lock. For example my house has schlage locks and if i replace all to kwikset will not be able to utilize my current keys at all, whereas if i used schlage i could just rekey the new shlage locks. Im still thinking whether or not i want to go with schlage zwave locks, because i've had great luck with my kwikset, however have not tried schlage yet so cannot compare directly.
As for light switch my recommendation would be linear light switches, if you ever plan to replace your lights with leds bulbs someday. Some of the ge light switches don't have option to wire a neutral which is needed for low voltage led bulbs to function properly(especially where dimming is concerned). Otherwise you can get flickering, and humming. All the Linear lights switches offer neutral wiring, and if you have neutral wire avaliable in your gangbox then the linear/evolve light switches i found work wonderfully.
