I currently do a lot of my monitoring via MQTT for my solar system etc. I currently use MQTT Alert and set up my alerts to ring my phone at top volume until silenced. But I have missed more than one alert because I don’t think the background agent is always active and it doesn’t necessarily start when I reboot the phone. While the application does “monitor” the MQTT connection, it only makes a short sound if it drops, with no followup until you notice that there was a notification and go back into it to figure out why the connection is down.

Does anyone have foolproof way of getting things like security alerts that will always trigger on the phone, without having to check the phone 10 times a day to be sure the application is on and the connection is active?
