Fox ESS app not working

slubell41 · Sun Apr 23, 2023 10:55 am

My FoxESS app is not working and does not show real time data nor battery status. I either get message could read data because not correct format or error code 41200.
Any idea why this is happening or it is a temporary glitch in the system. My installer says he is unable to logt on as well. It has been working well up to now since connection last week.

Time Sunday AM 23rd April

FoxESS status page says site is under maintenance until tomorrow AM.

jankowskier · Sun Apr 23, 2023 11:52 am

I am actually looking for exactly that, but don't find it. Could you share the location of the status page please?

I’m having the same issue

You see the message re the server flash up briefly when you try to log in. I did note that the server down time period times were from 2022!!! I hope that was just a cut-n-paste issue.

Trevorminor · Sun Apr 23, 2023 5:56 pm

Exactly the same issues. It would help if they used the correct date on the error message.
Somehow it’s also caused issues with our Chargemaster car charger.
Hopefully all will be resolved when the maintenance is completed.

Was a hard day not to know what's coming in and going out.
so our carcar charger sucks out our battary and we had alway to check on our inverter the status
hopefully history will be updated afterwords.

We had the same problem. If you log into the FoxESS Cloud website it says:
"FOXESS is under maintenance from 2023.04.23 00:04:00 to 2023.04.24 04:00:00AM（UTC +0）. Sorry about the inconvenience caused!"

So it should be back tomorrow morning at 04:00.

We can look at the Myenergi app for some of the information such as what is coming out of the invertor, plus the inverter physical control panel itself shows what it is currently doing at the moment. It's something at least.

When the message flashed up on the app it was so quick I couldn't read it. So I used my iphone screen capture function (press home button and power button at the same time) and then could view it at my leisure!

This is the main reason to have something else set up to give you a view of what the system is up to, IMO. NodeRed, Home Assistant, whatever - just something that talks Modbus, can log the data and give you some stats and graphs. Otherwise you're hostage to what happens to Fox's cloud platform.

Again down wtf. Just bought and had installed this system 4 days ago and 2 days it had not worked properly. In the morning app worked well, now is showing what battery offline and 0kw.

Do anyone know what I can use instead of this cloud? I can set it up, but I wanna know what to install

Clarkster · Mon Apr 24, 2023 10:13 am

Hi all, same issue here too. Unfortunately had 2 planned power outages yesterday clouding the issue, but had a server maintenance message when trying to log in to app all day yesterday, although the date didn’t make sense.

I can now log into the app but it now shows the battery offline. I have tried a full isolation and restart several times to no avail.

Typically it’s a rare sunny day in Cumbria and it’s all going to waste!

adammarshall · Mon Apr 24, 2023 10:37 am

Hi Yes, i have the same issue, App back up and running but show battery offline

Trevorminor · Mon Apr 24, 2023 12:00 pm

It looks like most features are back up and running. The battery off line bit being the most recent. Looking at their website it looks like historic date pre 23/4 will be restored on 6/5.

As the app doesn’t appear to be any different IE clearer, makes you wonder why we were subjected to the hassles yesterday. Perhaps it will improve on 6/5 too.

Home Assistant with modbus is the way forward. Completely avoids having to use the Foxcloud infrastructure.

CHorncliffe · Mon Apr 24, 2023 8:30 pm

My app is now working but according to the display the house is putting electricity into the battery. Is there a problem with the app?

fuzzballjunior · Wed Oct 11, 2023 7:01 pm

I’ve now got the same issue. Any ideas how to fix this? Server status is 100%

Annscullamus · Wed Oct 11, 2023 8:14 pm

I have this problem too. The app shows error 412000 ‘query data’ not responding’ or something like that. I have deleted and re downloaded the Energy stats app and the Foxess own app. Both are just blank. I have no idea why, and as a pensioner with No technical knowledge where do I go for help. My system was fitted on Aug 11 2023 so I am quite new, but the apps have worked perfectly since that date. Help !

Jibe · Wed Oct 11, 2023 8:47 pm

Have the same issue, also relatively newly installed system. I guess it is a maintenance downtime. Best is keep calm and wait. Maybe it will be up and running by tomorrow again. If not, call your Installer.

Update:12/10 --> works again for me

Try not to worry. There are other posts on these forums and on the Fox Facebook groups from lots of other users all with the same issues you’re describing. And I’m one of them. The consensus is that Fox are doing work on their end and the result is both the Fox and Energy Stats apps are down. In the meantime as long as there are no error messages on the inverter itself, your system will be working as normal.

Tom Beckmann · Tue Apr 30, 2024 5:37 pm

Sadly neither of the Fox apps report server down or server error codes.

At the very least they should report that and give a status page url so we could go and see if it was a planned outage or not.
I have on occasion (but not this time) seen a "timed out" message.... but even that didn't remain on screen so is useless.

It went down for me today and has now come back up.

Mirza99 · Sun Jun 23, 2024 3:12 pm

Right now, the Fox ESS app isn't functional. It's annoying since it affects how my energy system is monitored. In order to restore functioning, kindly take immediate action to rectify this issue and offer an estimated time of resolution.Fm Whatsapp

Hello

I'm new to this forum after having had solar panels installed on my roof recently and downloading the app to my laptop as I don't have a smartphone.

The app was working perfectly well until a couple of days ago since when the Live Status is showing all the energy going to Load Power and none to the Grid. This is clearly incorrect as confirmed by the bottom "Overview" line chart.

Any advice on what the problem is and how I might rectify it would be welcome. I'm not a tecchie by the way !!!

Thanks.

Hi, would you be able to screen shot the screens you are talking about and post them below so we can see what you are seeing.

Off the top of my head, this is usually indicative of the CT clamp being installed the wrong way round or in the wrong place, but if you can post those images it will help diagnose it - if you could also say which inverter it is solar only (F/S series), Hybrid with batteries (H/KH series).

The inverter is solar only.
