KC868-H16B Mqtt stops working intermittently

[hlavaste]

Hi, 

I have KC868-H16B relay.
What seems to happen is that Mqtt client stops listening to subscriptions after a while. 
I have ports 1-6 for lights, and port 16 for heating. 
Randomly, port 16 stops responding to mqtt state changes. 
Looking at the explorer, the set value is changed to 1 but state is not changed accordingly. This only affects port 16. ports 1-6 are still working. 
If I power cycle the relay, it's back to normal again. 
Version I'm running is H16B_V4.35. 
Any ideas? 


Thanks, 

Heikki
