Так же столкнулись с проблемой разрыва всех соединений mqtt-брокером. Это не первый контроллер с такой проблемой, но как воспроизвести пока не понятно. Может ли это быть связано с патчем? В интернете не нашел похожей проблемы.

Другими словами, брокер периодически закрывает все соединения. Кстати, возможно поэтому конвертер зигби перестает работать.
