From f575f8f62de14248da5ac31d33f57552f74d50cb Mon Sep 17 00:00:00 2001 From: Bastian de Byl Date: Thu, 1 Oct 2026 15:45:59 -0400 Subject: [PATCH] chore(hass): add one-off playbook to repoint tplink entries at IoT VLAN The IoT WiFi moved from Default (192.168.1.x) to the IoT VLAN (192.168.2.x) with fixed IPs reserved in UniFi. HA 2026.9.3's tplink reconfigure flow ignores the entered host and reconnects to the stored one, so this edits data.host in .storage/core.config_entries with HA stopped, matching entries by MAC and refusing to write unless all 9 match. Backs up core.config_entries first and always restarts hass.
