Green-Red-Red-Green LED Sequence

[overeasy]

@marnold

is it just a momentary press of the RST button?

Yes it is, then wait for it to completely restart before capturing the message log from the restart. It’s the trace that I’m interested in.

[marnold]

I tried pressing the RST button and the unit appears to reset.
From what I can see the blue led as well as the red/green one stop blinking for a second or so and the unit appears to come back up.
Its now flashing green-red-red and I cant seem to access it either by http://iotawatt.local/ or http://192.168.1.16 (which is its IP address).
I have a unifi access point and I can see that tis connected to my wifi

Is there anything else I can try to get the log/trace off it?
Apart from the RST press I havent done anything else such as remove the SD cad or power cycle it at the power point

Thanks, Mark

Sorry to dig up an old thread, but I’m having this exact issue. My unit is only a couple of months old. Is there anything I can do to help in the troubleshooting of the problem, or should I just get a replacement SD card?

For the past week or so, the web interface has not been available. It would just show

Not found: GET, URI: /

But my Home Assistant integration was still functioning, so I didn’t do anything with it. Last night, data stopped feeding into Home Assistant. I power cycled it twice, but nothing has fixed it. Home Assistant is not getting data, and the web interface just continues to show the above error message.

[overeasy]

What was the order number?

[HellHoof]

Order number: 127642

[overeasy]

I’ll send out a new card.

Hello,
Just had the exact same issue this morning - IoTaWatt is on and connected to wifi but Green-Red-Red-Green sequence and no connection on home assistant nor web browser. Based in the UK so presume easier for me to source a micro SD and perform instructions earlier in this thread? Order number 124528 if it helps with diagnosing anything?

[overeasy]

That should resolve the problem.

[phiebs]

Indeed it has, however a curious issue now: I copied over the config files so everything connected back in Home Assistant, however the “wh acc” figures are a crazy negative number (e.g. -2,649,312,955). Will have a poke around and see if I can figure out a reset - don’t really use this part but weird nonetheless.

[phiebs]

Seems that there was some spurious negative values on the watt readings when it came back online. Although data is feeding nicely into Home Assistant, I’m now unable to ping or access the web gui of IoTaWatt itself - any further ideas (have tried an off/on of the device to no avail).

EDIT: after searching around the forums I found this and it seems the Home Assistant Integration is to blame. Disabled and GUI works again. Still unsure on the spurious values but can deal with that now I can access the GUI.

[wattmatters]

I now have this Green Red Red Green LED sequence. I had Green Red Red, did a power restart and it’s now Green Red Red Green.

I assume this means the SD card is borked and I need a new one. I can get a replacement card but need some pointers on what to do next.

Are the links here still relevant?

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…

I have a Macbook, no Windows computers. No idea how I would connect an SD card to it.

EDIT: I have found a new class 10 16GB SD card, must have got it for something which didn’t eventuate. I think my Macbook has a built in SD card reader.

[wattmatters]

OK, for rebuilding the SD card, the instruction is to format in FAT32 format, which I have done.

Then:

Download the SD files from github SD directory

I’m at the linked Github page but how do I download the (right) files?

I can’t find a download files option.

I tried the Windows download link (I have a Macbook) and pasted the Github URL above and these are the files it provided:

Does that look right?

[wattmatters]

EDIT UPDATE:

I seem to have worked it out and got it all back on line. The link to use Windows to download the Github files also worked on my Mac.

I’ve lost whatever was stored on the old SD card, unless there is some other way to access it.

I managed to trace my all CT clamp wires and recreate the set up.

ORIGINAL POST:

I put the new SD card into the Iotawatt and it’s accessible, it connected to the Wi-Fi without needing to be reset up.

I plugged the old SD card into my Mac but it does not load at all. I was able to view the new card, so it looks as though the old card is corrupt and I have lost my config file.

So I’ll need to work out what’s what with rebuilding the config.

In the meantime it looks like the Iotawatt is resetting itself about every 30 seconds:

Contained instructions on how to recover your old config from the ESP8266 SPIFFS. That may be gone now if you created a new one, but take a look.

Your unit is now getting an exception while handling a query. This has happened before with Home Assistant and a brand new datalog. If you have HA, please stop the IoTaWatt integration and see if the IoTaWatt stops restarting. If so, wait a few hours before restarting the HA integration and it should be OK.

Thanks, looks like that’s gone now.

No matter, I have recreated it from scratch and took the opportunity to rename things.

Thanks again. Looks like it sorted itself out once I did some stuff on the HA end. The last message log entry was:

SD initialized.
3/17/24 02:06:14z Real Time Clock is running. Unix time 1710641174 
3/17/24 02:06:14z Reset reason: Exception

which wasn’t all that long after the ones I posted yesterday. Since then there is nothing new in the messages file.

It all seems to be working well, and also the HA integration (the forked one that works) appears to be nice and stable. Previously it used to drop out a lot even though the Iotawatt would be online and reporting OK via the iotawatt.local page.

Maybe the old SD card was causing issues. For the record this was the card in the unit:

In any case, the good thing was the unit gave me a clear indicator of what the issue was, and despite my uncertainty I was able to get it all back up and running by following the documentation.

Thanks again.

[overeasy]

Could you post a picture of the back of the card? Most of the SD card problems are related to a bad batch of those cards.

[wattmatters]

Sure:

[overeasy]

That’s the bad batch.
