I can not see anything about in the the wiki that says it can not use adfruit:)
This seems like an easier way to configure it rather then using the app on the phone. Does the settings get flashed aswell when you rewrite arduino code to it?
It would be really nice if we could get it to work with ardafruit aswell as mosquitto. For instance if I am brewing beer at my mates house i can threw an esp with dht11 in there, a powersupply and then just log on to ardfruit and plot the temperature.
Maybe I am missing something? For openhab purposes i would of course use mosquitto and the mqtt binding. But when testing out new sensor etc it would be nice to keep it off openhab.
