About us

mmmm… Us? It is only the Bot and myself. This project has started as a personal need for my home automation system & alarm. Then my friends and colleagues wanted to use the same API that I created so I decided to share it with them. When I realized about growing adoption, I decided to invest on AWS (Amazon Web Services) and GC (Google Cloud) to make it more reliable and accessible to everyone.
