I've used Staples Connect as the hub for my zwave door locks for over 3 years ago. It's true this product isn't sold anymore, but it's still being supported, and I have zero complaints. I could have gotten the SAME locks through my security alarm company but they wanted a monthly fee on top of the original purchase. Conspiracy theory time - Apple and Google want to collect all monthly fees and will stomp out any stand alone products that get in their way. I say this because I have the same problem with my DLink security cameras...alarm company wants a monthly maintenance fee on top of the initial cost of the hardware. Unlike the door locks, keeping the Dlink cameras updated has been a royal pain in the a**. I couldn't avoid the fee for my Ring front doorbell camera. Love the product. No update problems. DLink runs through my cable internet wifi and I *think* the Ring doorbell does too, but they have separate apps and I can't get them to go through Staples Connect...wish there was one app that would run everything, BUT I'd keep them separate if I could avoid more monthly fees. Wish someone with more technical knowledge than me (wide-open field there, guys) would address some of these things.
