Last week I was at the The Things Conference in Amsterdam with a collegue from TTN Catalunya. You could smell the hype. Most of the big players were there. I had the chance to attend some interesting presentations, talk at the booths with people from PyCom, RAK, WifX or SeeedStudio and meet and devirtualize some people like Gonzalo Casas or Andreas Spiess.

Their bet was backed on Kickstarter by almost a thousand people with almost 300k€ to help create a low-cost LRaWan gateway (and a platform and end devices too)....

It might not look as important as utilising the right pattern in the right place or defining your database model but my experience says that a good naming convention helps identifying design flaws. In a previous post I introduced the network I'm building for my home monitoring system. As I said it will be based on MQTT, a lightweight messaging protocol....
