Furrytail changed their HTTP API so this library doesn't work anymore at all. I think there's a better idea: teardown your feeder and sniff UART communication between the ESP8266 and main MCU. It would allow to design your own ESP8266 firmware and avoid Chinese cloud. I don't have spare time for that.
I'm too lazy to write any readme and the project is even WIP at this point. GoDoc should be enough for now.
If you have any questions about my shitty code, feel free to contact me by Telegram (@koteeq). I speak English and Russian.
