KC868-H32B Pro work with KC868-COLB + KC868-AK

[Aliman]

Hello Kincony,

I have success to configure My H32B Pro using apple home kits and also operate using momentary switch through kc868-AK.
When H32b Pro connected with COLB mini + KC868-AK is not working ( Relay cannot operated from switch and or KC868-AK).
I already followed the wiring as you provided in here, unfortunately it is still not working and I have no idea.
Could you give advise what the probable cause?

I attached 2 photos (H32B Pro directly connect to AK and connect to COLB and AK)
       

Thanks
Regards
