What is the most correct / compatible Zigbee structure for device with 10 sensors - endpoints / custom clusters ?

[roastcom]

I'm struggling to plan Zigbee structure for my device to use in z2m.

The device (based on ESP32C6) should have the following properties exposed (all read & write):

// main
    binary main_onoff; 
    int main_mode; //0-2
    int fan_level; //0-5
    float main_target_temp; // I saw temperature stored and reported as int *100 in Zigbee specs, but not sure how the division by 100 should handled 

// section 1 
    binary z1_onoff;   // 0-1
    float   z1_target_temp;  
    float   z1_current_temp; 

// section 2
    binary z2_onoff;   
    float   z2_target_temp;  
    float   z2_current_temp; 

and so on for 6 more sensors (8 in total)

// section 8
    binary z8_onoff;   
    float   z8_target_temp;  
    float   z8_current_temp; 

I want to be able to operate all on-off's normally in HA, how exactly the rest is handled is not a big concern as long as they're all read-write.

Should I be creating main endpoint (10) and then an endpoint starting from 1 to 8?

What clusters should I use? Nothing seems to fit perfectly, an on-off cluster and a temperature cluster are the closest, but then I'd need 2 for the temperature, and I also don't think those are read-write by the specs.

I'd love to just use a simple on-off for the 'main' and a custom cluster for the rest, but it appears z2m does not support that...
