Bticino F20T60A led blink

Configuration Zigbee
1

Hi, a integrate energy meter Bticino F20T60A in Zigbee2mqtt, work all but after some days found a led blinking orange.
I found in Zigbee2mqqt site the possibility to use the led for identify the meter.
In the documentation i found this:

{
    "identify": {
    "effect": "blink3",
    "color": "white"
    }
}

But, in home assistant it is correct to write it like this

service: mqtt.publish
data:
  topic: zigbee2mqtt/F20T60A/set
  payload: "{\"identify\":{\"effect\":\"blink3\",\"color\":\"white\"}}"

Thanks
