HB868 32 pro MQTT feedback and multiple clicks

[leliodm]

are you using KC868-H32B Pro controller? Do you use for home assistant?
1. controller also can work for ethernet ip by MQTT, can you take a screen photo of webpage, how you setting.
2. if you use KC868-AK + KC868-H32B Pro, you can download "KCS" firmware to KC868-AK, that can feedback mqtt message when you pressed a button. because H32B Pro, can't connect with switch panel directly, if use KC868-H32BS can do this .
3. if you use KC868-AK  + KC868-H32B Pro, support "1-click, double-click, HOLD ON" 3 ways.

Hi 
for 1. 
I am using the KC868-H32B PRO controller. I am trying to interface it to a piece of software that I developed that uses mqtt. I will also need to interface it to home assistant.  Therefore I would need the relay feedback sent over a topic on MQTT.
The screenshot of the ethernet settings is attached. 
I am unable to change the IP address of the mqtt server to my local server ip (say 10.1.0.80). Even if the GUI allows me to change the IP, after I press save it goes back to the value showed in the screenshot. MQTT works fine when I use it over wifi.

for 2. I just ordered the KC868-AK. I will interface it when it arrives. 

for 3. I also have a KC868-H32BS. Would the H32BS provide the feedback over mqtt and allow me to program actions for multiple clicks? I understand that I can also interface the HB32BS to tuya using the additional tuya module. Are there any limitations (like Alexa support)?

Thanks
