How long before Z-wave repair takes effect, why does a WiFi mesh router not help the Z-wave network, and how to set up direct association?

  1. What specific error are you getting for that device? And, yes, it might be significant if it’s a repeater which is used by a number of your other devices. See the FAQ.

FAQ: Zwave repair not working (how to fix error messages)

And in particular:

Note in particular that “failed to update mesh information” won’t cause a problem for the network if that particular device was a battery powered device because they don’t act as repeaters. But if that device is a repeater, it can’t be used in routing until the error message goes away, so you can lose access to a lot of other devices down the line.

As to how long it takes, it varies, but 24 hours should be long enough.

  1. The Wi-Fi subhubs are just like any other Z wave repeater on your network, like another light switch or another plug-in pocketsocket. They don’t have any special powers. In general they will be ignored by your other Z wave devices unless they are needed as a repeater, but they are not going to be the destination for a message: that will always be the primary hub, if that’s what you were asking.

The primary hub should be located centrally in your home, both horizontally and vertically, and that will shorten the route most of the time, although not always: it depends on signal strength and message traffic. if it’s convenient to you to move it into the zone where most of your Z wave devices are, that’s fine, as long as devices in the other part of the house still have routes back to it.

  1. As far as direct association, if you are using a custom DTH which allows you to set the associations, that’s a good way to do it. Otherwise, yes, the tweaker is the easiest. :sunglasses: note however that associations can only be set between devices of equal or higher security levels. So if you have any devices which are using S2 security, they can only be associated to other devices also using S2 security.
