Hassio 433toMQTT - put value to topic suggestion

[AlexMKX]

The Home assistant doesn't have conditions for a values.
When I describe sensors like this :

  - platform: mqtt
    state_topic: "homeassistant/rfgw/433toMQTT"
    off_delay: 10
    payload_on: "999999"
    payload_available: "999999"
    name: "motion_sensor"
    value_template: "{{ value_json.value | string }}"

  - platform: mqtt
    state_topic: "homeassistant/rfgw/433toMQTT"
    off_delay: 10
    payload_on: "888888"
    payload_available: "888888"
    name: "door sensor"
    value_template: "{{ value_json.value | string }}"

i'm getting errors in log : " No matching payload found for entity "
Which caused by the same topic is used for 433toMQTT.
In order to solve this - the value (which identifies the specific 433 button) should be appended to topic. To have topics like these :
homeassistant/rfgw/433toMQTT/999999 for sensor 1
and
homeassistant/rfgw/433toMQTT/888888 for sensor 2 respectively

proposed patch :
ZgatewayRF.ino@void RFtoMQTT() :
change
pub(subjectRFtoMQTT, RFdata);
to

#  ifdef HASSIO_433_MQTT
      char subject [1024];
      memset(&subject,0,sizeof(subject));
      char mqttval[64];
      memset (mqttval,0,sizeof(mqttval));
      itoa(MQTTvalue,mqttval,10);
      sprintf(subject,"%s/%s",subjectRFtoMQTT,mqttval);
      pub(subject, RFdata);
# else
      pub(subjectRFtoMQTT, RFdata);
# endif

This is available here

OpenMQTTGateway/main/User_config.h

Line 356 in a7575b2

//#define valueAsASubject true

By uncommenting the line.

We should add some docs about it.
