KCS firmware - MQTT LWT?

[erikwout]

Could someone with more experience check the code? Input and output are working. DAC1 and DAC2 do not respond.

I Think your code looks correct, My KC868-A4 gives a similar problem;
When publishing a MQTT message with KC868_A4/XXXXXXXX/SET

The relay(s) respond to the output commands output1:{"value":true}
the dac(s) do not respond to the dac1:{"value":158} or any other value

Firmware in use : KCS_KC868_A4_V2.2.6.bin
think we found an issue with the mqtt integration
