J’ai ajouté une rallonge usb entre le hub et le controller zwave, toujours sans optimisation…
J’ai remarqué que le problème ne surviens pas si j’effectue des actions plus ou moins toutes les heures. Aujourd’hui j’ai effectué qu’une action vers 15h et attendu la soirée pour tester. Et le bug est bien présent
