Salut,
je sais pas , c’est de la doc esphome. Mais je pense qu’avec bluetooth scanner sur mobile, tu dois trouver ces infos.
Pour la configue sur esphome, ces tags on besoin d’une connexion permanente, je sais pas comment ca peut fonctionner avec des Bluetooth proxy.
J’utilise l’intégration Bluetooth LE de HA et une clé Bluetooth. J’ai utiliser l’application Bluetooth scanner sur mobile pour trouver le MAC du iTAG , pour éviter de scanner tout les appareils Bluetooth sur HA.
dans mon know-devices.yaml:
itag_white:
name: 'iTAG White'
mac: BLE_FF:22:07:xx:xx:xx
icon: mdi:tag
picture:
track: true
itag_black:
name: 'iTAG Black'
mac: BLE_FF:22:07:xx:xx:xx
icon: mdi:tag
picture:
track: true
Pour esphome, j’ai tester c’est configue pour utiliser le bouton ( 2 click ) , ta peut faire sonner le itag. Ta le niveau de batterie et le rssi. Faut ajouter le tracker.

Pas contre, la pile a pas l’air de tenir longtemps. 1 mois, voir un peu plus 
Je ferais un retour, ca fais que 2 semaine que j’en utilise.
