J’ai fait quelques recherches.
J’ai la version OS

dans:
/homeassistant/custom_components
j’ai créé les répertoires:
zigbee-herdsman-converters/devices
dans devices j’ai créé un fichier : tuya_zbn_dj_63.js
Dans ce fichier j’ai mis la configue récupérée :
//Device type Router
//Zigbee Model - TS0601

J’ai restarté zigbee2mqtt
Mais ca n’a pas marché, il n’y a toujours pas de resultat.
A ce stade j’ai besoin d’aide 
PS: J’ai aussi testé cette config : ( peut etre n’ai-je pas mis la conf au bon endroit !??)
