I have set up my KC868-H32B with MQTT in late august 2021 (I have over a hundred devices working flawlessly with MQTT). I use the inputs to monitor doors and gates and the relays to act as push buttons or switch on/on devices that do not remain on for a long time nor change often.
In the last two weeks, the KC868 started to freeze (not accepting MQTT commands nor reporting status).
Power-cycling it solved the issue at first but not anymore.
I tried to upgrade the firmware today and it did not change anything.
I configured the HC868-32B to use UDP (and not MQTT anymore) and started issuing commands as described here but it also stops working after about 10 mn. Moreover, the Web interface does not answer anymore either (only ping keeps working).
My network and my MQTT broker are working OK (as mentionned over a hundred MQTT devices are working flawlessly).
Please advise.
