Send cmd via mqtt from Home assistant

[Patou]

Hello,
I do not find in the topics of this forum or in the doc the exact way to send mqtt data from home assistant using 'cmd'
On a mqtt tracker I see the messages so mqtt is correctly configured. On Esp1 this is the configuration

When I use the MQTT helper I can receive the message from HA

I tried following without success :

Code: Select all

    - service: mqtt.publish
      data_template:
        topic: 'Esp1/cmd'
        retain: true
        payload: 'event:ha_start'  

Code: Select all

    - service: mqtt.publish
      data_template:
        topic: 'Esp1/cmd'
        retain: true
        payload: 'event,ha_start'  

Code: Select all

    - service: mqtt.publish
      data_template:
        topic: 'Esp1/control?cmd'
        retain: true
        payload: 'event,ha_start'  

In the Esp1 device :

Code: Select all

On ha_start do
 event,publish_data
endon

But on the log of Esp1 I do not see the event ... I do something wrong bur what ??
Thanks in advance for your help

Finally found the correct syntax :
Need "xx" and not 'xx' !!

Code: Select all

    - service: mqtt.publish
      data_template:
        topic: 'Volet_Living/cmd'
        retain: true
        payload: "event,ha_start"
