Legacy Page Stops Working, MQTT working fine

[soggygeek]

From this discussion, two reports of somewhat the same issue (sorry, tons of off-topic postings in the middle of the two reports). https://groups.google.com/g/electrodacus/c/m0JlWcBBAOk Here is the first report: I could connect to the SBMS0 via wifi as usual (in my setup I have the SBMS0 connected via my router and the router assigns it a static IP#.) The home tab was updating as normal, I could also open the settings and the about tabs. When I tried to look at the legacy view tab, the page was flickering as if it was updating, but showing half or one quarter of the static page, but no data. I tried with both my laptop and phone, cleared the browser cache on both devices.

Here is my near-identical experience: (SBMS0 latest hw, Version: 0.3-dirty) after about a month or more of operation as normal on the Electrodacus SBMS0 with wifi, with really reliable connection with the wifi, I had the same symptoms this morning. I am using MQTT from the Electrodacus to a Mosquitto Broker on a laptop to a node-red server showing the data. I also have another browser tab with the Electrodacus legacy page up. I mainly monitor the node-red page, because it has a nice graph of what's going on. But right at charge termination, I like to see the Electrodacus legacy page because it updates faster than my node-red display (which by design only updates every 5-10 seconds). On the legacy page I can see clearly what's going on with balancing. This morning, the MQTT publish was WORKING, but the "legacy" web page was not. I could display all the other pages and they appeared OK (I forgot to notice if the home page data was actually updating). I tried refreshing the page, I cleared browser cache. I tried a different browser (on same computer). Before clearing the cache it was showing some data but not updating, and not all the data (maybe only the SOC). After clearing cache it was all blank except the basic framework of the page. We used the "turn wifi on and off" mechanism on the Electrodacus to cycle power on the ESP32 and everything worked after that. I will report again (and be a little more attentive to details, take screenshots) if it happens again. Not a big deal to toggle the wifi board if you are present, but if you are trying to monitor from afar, that's impossible to do.

BTW, rebooting the ESP32 did not lose the 12 hr history data. And it looks like while it was not responding as a web page, it was still gathering historical data.

Hi soggygeek,

This is probably related to issue #23

I assume that sometimes something goes wrong with the serial communication, maybe due to EMI or similar issues. This causes corrupt data in the buffer of the ESP32 and breaks the legacy webpage. If the issue happens again, please go to /rawdata and paste the contents here so I can have a look.

The history data won't be lost because it is actually stored on the SBMS itself and transmitted completely every second.

i have had the sbms0 maybe 6 months or more and i have has the legacy page do this same thing a number of times and turning the wifi on and off again seem to temporarily fix this issue. also after setting up mqtt it worked for 1day and then i cant access the settings to change the mqtt data information and i also cant access the settings under that data menu. see image below. how can i fix this. would really like to get the mqtt working again.

[armageddon421]

Please go to /rawdata if the legacy page is not working and post the results here.

I am unsure why the settings screen is not working properly. You may try opening the developer console of your browser and look for any script or network errors and report your findings. You can try updating to the latest version using any of the methods outlined in the readme. This should reset any config and thereby fix any problems with it.

[armageddon421]

Correction: it may be /rawData with a capital D

[ninlee]

Problem happened again today. had to reset the wifi to get it back.

i looked at the developer console in my browser but wasn't able to see any errors given that i am not even sure what to look for.

please see the output of the rawData.

i am having problems updating using the methods you outlined in the readme. i got at far as platformio run and then there is a bunch of errors.

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
  https://docs.platformio.org/page/faq.html

* Report this problem to the developers
  https://github.com/platformio/platformio-core/issues

============================================================

[armageddon421]

This is a strange error, as the repository definitely exists. Are you running the latest version of platformio? Can you try updating everything? pip install -U platformio or pio upgrade

[ninlee]

you tried all that... You're up-to-date! PlatformIO 5.1.1 is currently the newest version available.

[Everlanders]

I just wanted to chime in and +1 this issue.

We've got an SBMS60 and an SBMS100, these were equipped with a ESP8266 and so I've connected an external ESP32 to the TX pin on the SBMS, and then we're curling the data and storing it in InfluxDB. (work in progress, any help getting this into InfluxDB appreciated.)

Everything works as you'd expect, except every so often the rawData hangs and we get the last known good values for 1/2 an hour or more. Power cycling everything works, But now that I've seen this I will try and catch the rawData for you.

[Everlanders]

Well, that didn't take long, The Legacy Page is stuck with the timestamp 22:33 for the last half an hour and the reading aren't updating.

This is the rawData from this event.

@Everlanders the rawData looks good but must for some reason not be updated anymore. By any chance, do you have MQTT running and can confirm or deny that MQTT is still working in that scenario?

[Everlanders]

No, I wasn't using proper MQTT, I've been using Blynk (quasi mqtt) (but I'm currently moving away from that as much as I can.)

I was just using this to get the SBMS data onto my network and then I was parsing it in Python to Blynk, InfluxDB, and others.

I have now moved to a wired serial connection. https://github.com/Burtond/Electrodacus

I was getting several bad readings a day there too, (3485% SoC, etc) but have fought through it, and now have it filtered nicely.

[helgef]

Just got this as well. Issue present in both the legacy view inside the vue application and also on /sbms.html directly

Seems like the issue us with the javascript parsing the rawData: Uncaught SyntaxError: Unexpected identifier (at rawData:7:9)

rawData looks like this:

As you can see indeed is line 7 suspect: var dm t="############################################################";

Not sure what happens here.. Might look at the code generating rawData from uart when i get home

[helgef]

So I traced down what is happening here.

1. The legacy page calls the /rawData inside a Githubissues.
2. Githubissues is a development platform for aggregating issues.
