I am just finishing my move to HA from SmartThings - 146 devices, 45+ of them Z-Wave. I have two Schlage Z-Wave locks and have added Keymaster to manage 8 user slots. In Keymaster, I have set just three fields for each slot. The Enable toggle, the User Name and the 4 digit PIN.
I think I understand Keymaster it and it works well, except… The two locks work correctly after I enable the slots, then periodically (every day?), all 8 of my defined user slots go from Enabled to Disabled. They of course stop working, leading to calls from my spouse about “I can’t get into the house!!!” I have run the utility to Rebuild network routes. No change.
With 45 devices, my Z-Wave network should be pretty robust. There are several mains-powered Z-Wave outlets adjacent to each of the locks 3-10 feet.
I am ready to write a YAML automation that monitors and resets that Keymaster parameter, but that feels like overkill.
Please help get my 45 year marriage back on track.
Is the enabled toggle getting switched or are they slots getting reset?
There’s no reason that they slots should be getting disabled or reset unless you have something that is doing that to them.
Also, if you’re not using or planning to use any of the advanced features (time/day of week or date ranges), make sure that you’ve got them turned off in your configuration.
Thanks for the insights. The slots were just getting disabled, not reset.
I think I may have found the problem. I inadvertently allowed all of the 500+ Keymaster entities to be exposed to my Amazon Alexa system. Alexa was constantly querying all of them for status. I suspect that huge amount of traffic was causing the problem. I have removed them all from the Exposed list and I have some temporary YAML code monitoring the problem.
Lesson learned… Don’t let HA automatically expose new Entities.
I finally found the smoking gun for this problem. Classic shoot yourself in the foot problem. I have an Automation that turns off virtually everything in the house at 10pm. I was inattentive at what I added to that and added a turnoff for all Switches. That of course disabled all the Keymaster slots.
