OTA over MQTT

[papperone]

Not sure where's the right place to post but I am sure this feature will be very handy and looks easy to be implemented.
Actually I've found even a working example but not sure how to integrate seamlessy into ESPEasy code without breaking anything --> https://github.com/Imroy/pubsubclient/b ... 66-OTA.ino

I've not much time myslef but maybe this can be a nice addition to the ESPMega project
