Blank Status Page

[davidg]

Hi all

I have used my iotawatt in a while; but got it back working yesterday - however today, the status page is blank:

The log looks like the following: I have deleted the datauploaders; but i still cant get it to work

Any pointers would be awesome.

The exception is happening in the code that is creating the status data for the datalogs and integration log. I saw that you had an integration created. It may be related to that, can’t say without knowing more about the history.

If you could upload your config.txt file I can strip out some of the possible causes and send it back. It may come down to deleting the datalogs, but not ready to make that call yet.

UPDATE: You can upload the config in a Private Message. Just click on my ID and click “message”.

Did this ever get resolved? I just went through a very similar series of events, revisiting my Iotawatt for the first time in quite a while, and while the status page displayed values for about 5 minutes, now it stays blank. My message log displays this sequence over and over:

The IoTaWatt is encountering an exception when handling the status request. The trace indicates that it caused by something related to one of the datalogs or one of your integrations.

I can see by the two restarts that it appears the history log is trying to recover. The full datalog would probably shine some light on the cause, but it really doesn’t matter at this point.

Change the output “Cum_house_heat” to reference “House_Minisplit” rather than "House_Minisplit.pos. The I would recommend that you delete the two integrators as one does not appear to be referenced “Water_heater” and the other “House_Minisplit” should be unnecessary as the input “House_Minisplit” should be a monotonically increasing value.

Try running STATUS.

If it still takes the exception, you will need to delete the history log. Type the following command into your browser:

http://iotawatt.local/command?deletelog=history

The IoTaWatt will restart and should work OK. If not, you probably need to replace the SDcard:

Remove/replace SDcard

Sometimes it becomes necessary to remove the microSD card. You may need to replace it or look at the message log if the device isn’t working, or maybe you want to back up the datalogs. For whatever reason, it’s best to be careful as the type of holder and position makes it easy to damage during removal. Power down the IoTaWatt by removing the USB power plug and AC reference plug. 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…

Thank you! Updating the Output to reference “House_Minisplit” seems to have done the trick! Really appreciate the help and prompt reply!
