At this point, I have a few IOT things on my home network. The first were a couple of EcoPlugs Wifi outlets that I use to control my gutter heaters in the winter, and the next was a custom garage door controller. For the former, I’m basically controlling them by using a replay attack (I hope to make a post about this soon)…re-sending packets that I observed the EcoPlugs app sending. For the latter, I’m using a custom http interface. Since both of these contain an ESP8266, I’d like re-program them and unify them both to use the MQTT protocol.
While browsing Hackaday, I came across their Minimal MQTT series. In this post, I’ll begin by walking through that series, noting my thoughts, then conclude by getting things set up the way I want.
