I would appreciate you help and guidance again, please. After adding a CT to the last vacant position (14) I selected the EmonCMS server, inserted then saved the CT details. A short while later this window appeared:
After switching off the power and restarting the IoTaWatt the led displayed a ‘green-red-red-green’ sequence. In accordance with the advice on https://docs.iotawatt.com/en/master/troubleshooting.html I mounted the SDcard in another computer and found the config.txt file empty!
So my question is – where can I obtain a suitable replacement config.txt file to suit IoTaWatt 4.x, Firmware version 02-05-02?
