Virtual Door Button
In our reception our staff needed to be buzzed in, so we decided to take our own medicine and create a virtual button.
This code allows you to send a RPC (Remote Procedure Call), which looks like a normal HTTP call from any browser. We used Mongoose, since it is really easy and fast to work with and it's built-in OTA (Over The Air) update of code, means we could install our tech and still over time upgrade the firmware, without dissembling it for reprogramming.
