How do I configure an automation with an MQTT sensor so that it triggers when the value is [1]?

[Matth73]

Hello,
I want to create an automation to set the maximum charging current on a wallbox to 6A when the value on an MQTT sensor is 1.
The MQTT sensor is published in Hass.
I’m stuck on the trigger.
How do I configure it so that it detects when the sensor switches to “value [1]”?

The MQTT sensor is published in Hass.

What exactly do you mean by this? Is the data available as a sensor? If so it is an entity and you can trigger on it like any other entity.

If it’s not available as a sensor, then set a sensor up.
