Error lights but config.txt seems ok

Support
1

For a while my Iotawatt has been broken and Ive just found the time to investigate properly. My device is flashing GRRG indicating a config.txt problem, and web connections are refused (it doesnt give the GET message Ive seen mentioned, just refuses the connection)

However when I plug the SD card into my computer it seems fine. The config.txt file is included below, but Im unclear what else I could check in order to get the Iotawatt booting again?

Thanks in advance!

Funny, some extra unplugging and extra reboots and it does now seem to be working again. There is some commentary in the log about a failed update on 1st May - which potentially killed it - but I have no idea why the various reboots I have done since 1st May have not fixed it and this time it has come back to life.

Might be prudent to replace your SDcard.

Thanks, ok will take a backup for sure and I do have some in a box that should work. There isnt anything special about the one you provide, just a standard class 4/10 uSD should be fine?

Does it matter that the history logfile is ~2gb?

This should explain it.

copying the /iotawatt directory with contents should go pretty quickly on a PC.

Rather than download the root files, you should just copy the entire card contents to the new card.
