Since version 0.112.0 there is problem with MQTT, my devices were working flawless until that update.
As you can see on picture, all 8 relays are on single NodeMCU, first one is working, rest are off. Explain to me, how one from device can be online and rest offline? There is single callback method in code that listens to all subscribed topics at once, if there is not connection, all should be disconnected, if there is connection all should be connected.
