**Update** Never write a review when you are in a bad mood. I should have made a request instead of being a jerk about it. I apologize for being so brash. ----original---: The developer obviously doesn't understand mqtt servers very well as he thinks an underscore (_) is not an acceptable topic character. This app is useless as it won't accept "valid" topics, such as home/control/switch/master_bedroom_lamp/state because the dev only allows number, letter, forward slash (/) and dash (-) characters.
Nice application. Very easy to configure.
Awesome Application.Perfect for home automation.
