Please, pretty please, add something to the “Payload” option, in order to customize it somehow, it is too not usable in this moment.
For example, I want to make a trigger which will trigger only if the payload contains a specific string, I don’t want to trigger only by the entire payload received. It could work with a part of it, detecing some strings or even using a more complex template.
The workaround which all uses, by adding a condition to the automation, it is not the perfect fitt, because the “trances” will not be usable anymore. The trigger will fire everytime, no matter that condition, the condition will only block the automation to continue, but the trigger already has been fired…
For some situations, like mine, not even a MQTT sensor will help, thats why I think that customizing the payload from the trigger, will be the perfect solution.
