WD500Z-1 and WT00Z-1 Indicator Lights not Always In Sync

Other Devices & Integrations Lighting & Load Control

Hi everyone!

I have a three way switch setup in the kitchen that consists of a WD500Z-1 and a WT00Z-1. When I turn on/off the lights via the WT00Z-1, the green indicator light goes out/turns on on both switches. When I’m controlling the lights from the WD500Z-1, the status light on the WT00Z-1 does not always stay in sync (eg. the light on the WD500Z-1 is off while the light on the WT00Z-1 is on). Has anybody else observed this behavior? I’m on 7.10 currently.

You’re saying that, when operating the main switch, sometimes they do remain in sync, or they never remain in sync? Did it use to work correctly and now doesn’t or is this a new installation?

After being configured, this switch pair should operate regardless of Vera’s UI version. Even if you unplug Vera’s power, these switches should continue to work correctly. My immediate suspicion is a communication issue. Do you have any/many other devices in close proximity to these switches? A sparse mesh could create the symptoms that you describe.

That is the default behavior of the WT00Z-1 switch. From the manual:

Poll: Minutes The WT00Z-1 will poll the first node in Group 1 in order to keep itself synchronized with the group if this configuration parameter is set to 1. How often it will poll is configured using this parameter. ? Parameter 20 ? Length: 1 Byte ? Valid Values = 1 through 255 (default: 2)

Poll First Node in Group 1
The WT00Z-1 will poll the first node in Group 1 in order to keep itself
synchronized with the group if this configuration parameter is set to 1.
? Parameter 21
? Length: 1 Byte
? Valid Values = 0 , 1 (default 0)

I keep a poll interval of 2 minutes I think? I can’t remember off the top of my head, so there is a delay of sync of at most 2 minutes, but then everything stays very cose to being perfectly in sync.

Another thing you will notice with the 3-way switches is if the vera ever goes away (vera crashed, unplugged, etc) the 3 way switch will become very delayed when turning the switch off and on because vera automatically decides that it needs to add itself to the associations group. You can not undo this through the vera interface, but if you have a secondary controller that allows you to inspect and configure associations you can remove the vera from the association group to use the switch as it was intended (i.e. no coupling with the controller).

Z-Waver,

This is not a new installation, I have had this setup for about five months. It has never been in sync, but I am just now digging into it. The only time the LEDs in the switch stay in sync is when one operates the kitchen lights from the WT00Z-1. I have a 1300 SF house. Within a ten foot radius of the WT00Z-1 there are four WD500Z-1 switches, a GE 12730 fan control, and the Vera itself. I figured I would throw my version in anyways since I had an upgrade (I think it was 7.09) that deleted my association to the WD500Z-1. Sorry if it was extraneous information.

Erasmuz,

I did a test this morning. I turned on the kitchen lights at 9:30 using the WD500Z-1 (which is associated to group 1 of the WT00Z-1 in Vera, the only associated switch mind you). At 9:38, the light on the WT00Z-1 was still on, and that is when I left. I shut the lights off using the WD500Z-1; not once did the LED on the WT00Z-1 change state.

I found this link with the full documentation for the WT00Z-1: http://www.pepper1.net/zwavedb/device/485

Parameter 3 on that list states that the LED on the WT00Z-1 will be on whenever the status of the status of the devices in group 1 are ON. This is the behavior I am seeing, but only when I control the lights from the WD500Z-1, not when I control from the WT00Z-1.

Parameter 20 and 21 you have already provided. I am going to switch parameter 21 to a 1 Byte Decimal with a value of ‘1’ to see if it will look to the WD500Z-1 for a state change. With this in mind, I will hopefully see it sync up within two minutes. I will let you guys know what happens when I do this. If you have any more ideas in the meantime, feel free to post them!

Though I have not experienced the issue myself, I have seen a couple of people report a similar situation. They resolved their instance by also creating an association on the WD500z-1 to the WT00Z-1.

Frankly I would probably try excluding both devices and beginning again, but the above approach may work for you.

Hey everyone!

I have verified that switching parameter 21 on the WT00Z-1 to a 1 Byte Decimal with a value of ‘1’ has fixed my synchronization issues. I tested this by starting a timer and then turning on the light from the WD500Z-1. Now, every time I turn the lights on, the LEDs on the switches fall into sync within two minutes. Hopefully this will help someone in the future!
