Light status unknown - MQTT (PHC PEHA domotica)

Helo,

I’m implimenting my home lights into HA, I have a domotica system PHC from PEHA, i’m using MQTT from the mosquitto broker on HA. I can switch the light in HA but the status is always unknown.

Yaml config:

mqtt:
  light:
    - name: "Kantoor Hanglampen"
      unique_id: "omx_2_out7"
      state_topic: "phc/p2m/sta/omx.2.out7"
      command_topic: "phc/m2p/cmd/ccmd"
      state_value_template: >
        {% if value == '0' %}
          off
        {% elif value == '1' %}
          on
        {% endif %}
      payload_on: "omx.2.out7.on"
      payload_off: "omx.2.out7.off"
      qos: 0
      retain: false

Mosquito listening to topic: phc/p2m/sta/omx.2.out7

status 0 is correct for when i switch the light off, and 1 for on

Message 4 received on phc/p2m/sta/omx.2.out7 at 10:32 AM:
0
QoS: 0 - Retain: false
Message 3 received on phc/p2m/sta/omx.2.out7 at 10:32 AM:
1
QoS: 0 - Retain: false

So the status is reaching the HA correctly I assume, but it is not showing in the entity:

Can somebody suggest a way to include the status?
