Ability to set new "one off" alarms using MQTT

Ability to set new “one off” alarms using MQTT.

I am a home assistant user and i really think behing able to set a “One Off” alarm based on a MQTT message or a webhook would be something really beneficial. My phone has a fixed IP adress on my wifi network which could allow me to just send a webhook to it. But it could also connect to my MQTT broker and receive commands. Thats would be a great addition.
