LZW31-SN: Force-Add as NON SECURE?

Yep, that used to be the case but it has changed. Are you trying to associate with an Illumin bulb? You can force that to pair non-secure, so the intent is to allow it to pair with a ZWAVE_S2_FAILED dimmer.

An older workaround used to be to get the device as far away as possible from the hub, but I’m not sure if that’s a valid workaround any longer.
