History log empty

Hey Bob,

I am running firmware 02_08_03 and noticed today that the History log has no information. The current log shows 2 years worth of data. Is there a reason why the history log would not show any dates?

Thanks in advance for the help.

It’s probably damaged. Check the message log for a message during startup.

Your current log has one year of history. I would recommend replacing the SDcard. Copy all of the files from your old card except the History log (/iotawatt/histlog.log).

When you restart, it will take a long while (probably a day or so) to build a new history log from the current log. Best not to do anything with the configuration and stop any uploaders while this is going on. You can watch the progress on the status display.

If mounted to a wall, remove the mounting screws. Remove the four Philips head screws in the back. Remo…

Building a new SDcard

It can become necessary to build a new SDcard. This post describes how to do that. IoTaWatt uses a microSD card, formatted to FAT32. New units use a 8GB level 10 card. Any card 4GB-32GB level 4 or 10 will work fine. Obtain a new microSD card or reformat an old card to FAT32. Download the SD files from github SD directory If using windows, this link will downlod the files into a .zip file. Copy the files to the root of the SDcard. If you were able to salvage the config.txt file from the ol…

According to the message log, the history log started failing last month. Prior to that, there were no errors.
