Stopped communicating. RED-RED-GREEN LED
Started broadcasting “ESP-F344B2” instead of iotawatt.
After reading some posts here, I replaced the Micro-SD card.
Started broadcasting “iotawatt”.
Is getting a DHCP address OK, but when I browse the IP, returns:
Not found: GET, URI: /
The original SD card can’t be read by any systems I tried (MacOS, Debian, Win-10)
New SD card works, here is what was written to it:
** Restart **

LED is RED-RED-GREEN-GREEN, so what do I replace the missing/corrupt config.txt file with?
It is not entering AP (Access Point) mode.
How can I access the iotawatt to configure it?
The MicroSD was not readable, and could not be mounted by anything I have.
I have two IoTaWatt devices.
They are not identical (different CT’s)
Took the MicroSD out of the working unit, copied the contents to a directory on my PC.
Copied the files from the PC to a new MicroSD card, put that in the dead IoTaWatt device.
It came back up and worked fine, after I edited the configuration to use the type of CT’s on that device.
It might be possible to get the same files here:
(I did not try it, as I had a duplicate system to copy from)
Note that there is a copy of your last good config file in the ESP8266 SPIFFS file system. This post explains how to build a new SDcard and how to access that SPIFFS copy of your config.
