Kwikset 910 Z-Wave goes offline after about an hour

Remember that zigbee is subject to interference from Wi-Fi. One reason it is not as popular for locks is that if you are trying to boost Wi-Fi around your door in order to support Wi-Fi cameras or video doorbells, you are quite likely to interfere with the lock’s operations. I’m not saying it’s impossible to use a zigbee lock successfully, but given that smartthings gives us no network diagnostics, it can be very tricky to troubleshoot if you do run into problems.

The beaming used for zwave locks does run slightly slower than regular Z wave, but it shouldn’t be noticeable to most people if you have a good mesh.

I would not say “secure devices slow down your zwave mesh” because
a) that’s not what is happening and
B) it’s going to confuse people about the new S2 security protocol, which is in fact faster than older generations. :sunglasses: For example, I haven’t seen any complaints about the new ring protect alarm system, and it’s all S2 zwave.

BUT no controller on the market supports it, yet and it requires an update to the 500 chip. These older locks and controllers still use the S0 which has been proven not to be as good as advertised.

I have Zigbee contact sensors on the doors and had no issues for years. I started with a Z-Wave centric system and slowly building up my Zigbee mesh. I am at a point where I think that I can shift to a Zigbee centric system. I like the advantages it offers over Z-Wave.

There are S2 protocol controllers out now. For example, the one for ring alarm. (S2 is required for UL listing as a security device.)

Alarm.com’s new Gateway, probably for the same reason.

Lifeshield Base S30 hub (this is the security company the ADT just bought)

For that matter, ADT, Vivint, and DSC all have them, only available with professional installation.

As far as DIY home automation, there are some that you can buy now:

The new Zooz USB stick ( The first USB stick with the S2 protocol)

The zlink zl100

Powerley Energy Bridge ( distributed through utility companies as an add on to a smart meter)

The Connectair CW7 (Canada)

Smanos K2 security hub (UK)

Honeywell has one in the pipeline, but I don’t think it’s been released yet.

But anyway, there are a bunch of them out now.

LOL point taken, I meant none of the popular DIY controllers support S2 yet, that also offer Zigbee. And people would still have to replace their older locks with Z-Wave Plus locks to take advantage of the S2, don’t they?

Update: The new Schlage FE599NX came yesterday afternoon and I excluded the old Kwikset 912 and added the Schlage to the hub, all apps, DTH and automations. The whole process went very well and, so far it hasn’t dropped from the Z-Wave mesh at all. I know it’s a relatively short time to judge, but by now, the 912 would have dropped a minimum of 6 times - probably many more.

First impressions of the Schlage is that it’s much quieter, responds much more quickly to commands and automations and is much more sturdy than the 912.

Good luck to those of you trying to solve your Kwikset connectivity issues.
