Informations brutes Sonof SNZB-03 et SNZB-04

Bonsoir, je voudrais récupérer le modèle des piles dans chaque boitier sonoff mais j ia du mal à comprendre la logique dans informations brutes.
On ma déjà aider au niveau du % de la batterie mais je n 'arrive pas à trouver la CR2032 ou la CR2450.
voici les informations brutes du SNZB-03 :
