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.
Creating an alarm via MQTT would be really a gamechanger for me. I have all my calendars and the logic which events should trigger a wake up call in Home Assistant. The easiest way for this would be an enhancement to the MQTT Functionality of SAA.
Extra points if the “Set” alarms could be seen on the MQTT Broker too (maybe retained messages) 
I really think automation should be a big next step for SAA
I’m afraid you cannot change the MQTT topic at the moment. You can only read the existing topic.
I recommand you use MQTT explorer to find out the different values. This is one of the reason why i opened this enhancement request with the developpers in the first place.
Setting up alarms using MQTT would allow me to use my business calendars (not on my phone) to setup wake up times. I am already using them with home assistant to trigger other household tasks so as heating up the electric car in winter. Curtain control etc…
