No, I wasn't aware of the ESPEasyMySensors PoC. Nice. And if you implement a "super"-gateway that one would gather information from all of the others? Haven't really thought it through enough to say if it is realistic or worth the trouble. I mean data can flow directly from a ESP node to the controller. Why bother implementing another failure source by routing them through a single gateway. Unless you mean taking advantage of the Ad-hoc network features of WiFi to get more distance/coverage out of it.
