+### Network: cAP ether2 ports for Olimex Bluetooth proxies
+- **[NETWORK]** CAP XL ac (192.168.10.2): ether2 `pvid=30`, untagged on VLAN 30 (was pvid 1, so no VLAN was allowed). CAP AC (192.168.10.4) ether2 was already VLAN 30 (since 2026-09-27). Both feed Olimex ESP32-POE-ISO BT proxies (corridor, living room). ether2 PoE-out is passive 24 V (bundled adapter), too low for the 802.3af Olimex, so the Olimex boards take USB 5 V power.
+- **[SERVICE]** Olimex #1 flashed with ESPHome 2026.9.1 Bluetooth proxy over Ethernet (`corridor-bt-proxy`, LAN8720). Config kept locally in `~/Homelab/esphome/`; HA adoption pending.
