June 2019: August Pro Z-Wave commands fail if August app is not in use (previously worked fine)

There are other community members who have been reporting this problem for about a month, but it’s not all August owners and no one has been able to figure out what’s going on.

August Pro no longer responding consistently to SmartThings

I’ve been using an August Pro connected to ST for about a year now without any problems. However, within the last two weeks, the August has stopped responding consistently to ST. If I click “Unlock” on ST, it shows that it’s sending the command but the door never responds or unlocks. It works sometimes, but I really can’t get it to respond consistently. Mostly it locks fairly consistently, but not 100% reliably, either. This is very frustrating. The live log on the graph page isn’t helpful at all (it just says “[DTH] Executing unlock() for device Front Door”). I tried changing the DTH from “Z-Wave Lock” to “Z-Wave Lock without code” to see if that helped, and it doesn’t either. I shot off emails to both August and ST support but no responses yet. Anyone know what I can do?

Definitely report it to support. The more people who report having a problem, the more resources they will assign to investigating it.

SmartThings Support

@rboy , I don’t know if you’re getting many reports of this, but at this point there have been at least four people in the forum reporting that they had an August lock that had been working just fine for some time and now is unreliable. So I don’t think it has anything to do with repeaters or batteries, it appears to be something in the Z wave implementation. Or the August firmware. But since it’s not affecting everyone with an August lock, I’m not sure what’s going on.
