does the job well
This application doesn’t have a lot of frills but it gets the job done. It is combined with a cloud-based API which allows you to send notifications to your phone from any of your systems. I used it (for example) to monitor my garage door and other home projects. I also get notifications that tell me when my servers restart, etc..
It’s a bit expensive from an app perspective but that is because the API service (currently at no additional cost) comes with the application.
