I have an emonESP running 2.2.3 and want to update it to the latest version 3.0.0, the firmware upload button would not work so i removed the unit and tried to update via the serial port. i loaded the source into ArduinoIDE and flashed it ok. but now it shows up as smartplug7510 also on the system page it shows
I am also unable to upload the firmware from the webpage.
