No Values!

[muhkuh666]

Hello,

is someone else expecting no values with the up to date HA Foxess?

[Maesch1992]

I think about that -> https://www.youtube.com/watch?v=jRTE9UZkpHU But I understand that maybe it was off from my inverter. Yes?

This is the ModBus integration. The only way to get your inverter data into HA now.

But i dont work with the new Firmware right? Because Ethernet is deactivated. I got the foxess smart lan dongle. But it doesnt shows IP Adress or Mac adress in Inverter or Router.

ModBUS still works fine. The LAN port on the inverter doesn't work with newer firmware. I don't know what the smart LAN dongle is.

Not familiar with it, but looks like that just sends inverter data to the Fox Cloud platform. Doubt you'd be able to get any data directly from that into HA. ModBus is still the only viable solution for HA integration, unless Fox reverse the changes they made last night.

@macxq needs to make contact with Craig Wollaston at FoxESS UK so that he can be added to the list of developers who need access to the cloud API. I have contact details if he needs them, but Craig has posted on the FoxESS Solar/Battery Owners Group on Facebook. Nothing end users can do at this point.

@macxq How do I find them on FB? I dont use FB much and cant seem to find the group, could they post something on Lemmy?

[manuelsirianni]

Please, take all of us updated with outcomes. I have no modbus but only a usb to Wi-Fi That can’t be handled directly.

thanks!

Anyone know if there is any chance to obtain data from WIFI logger ? There is open web service on it.

[pkudlins]

in aplication and especially in web view there is option to see detail status of inverter / volts , power generated etc ... / could someone find what is url to call this / I tried but cant find exact url ...

It's https://www.foxesscloud.com/c/v0/device/history/raw - but you need to be authenticated to see data. Authentication is the root problem of all this. This integration was getting the data from there too

[kamyk]

QQ: is it possible by that ModBus integration to see a value by WIFI in HA for example? I see IP address and a Foxess local webpage, but no idea if I can see a value there. I will check but maybe somebody already know? Best

How did you get the local IP address, my router is not showing the unit or its got a odd name in the DHCP table.......

I have seen an Adapter wifi SSID. I have connect there and have check. You can always try to search for MAC address. But I don't see any data yet or never. I will check next hours.

Same issue. See no Mac address, IP address or something else. So I don't know how to connect to modbus. I hope the cloud integration will be fixed soon

local page allows only to insert Wifi details for it to connect and upgrade firmware. Data isn't exposed there

[kamyk]

Why?! :) It will be so great to see that data by local page. That will fix all issues and not need any Modbus converter. Maybe some day.

[snaiperr]

They are selling these data, access from local network possibly could block data to cloud.

I have requested numerous time from the foxess support to provide data and address list for the sensors for rs485 protocol - they have never replied to me.

Now I see two options:

1. parse web data from cloud such as "web user" without api
2. replace foxess cloud with the local service "cloud" - I see in the router that inverter sends data each 15 second to foxesscloud port 10001, thus we just need to replace their host with our own(dnsmasq easily helps us with this)

Boycott to foxess as this very unacceptable step from them

Have you tried that already? I see you already checked a port.

Best,

Should we really discuss configurations etc. here now? Let's please keep the topic of this thread to the actual authentication issue. Otherwise it's hard to follow the actual issue/solution here

[MartinBlackburn]

From a little more poking around. Calls to get the raw data (https://www.foxesscloud.com/c/v0/device/history/raw) need to be auth by three headers:

• Timestamp - a timestamp in milliseconds
• Token - fetch via an auth call
• Signature - generated for each request

The signature is needed to obtain the token via the login call - which is the source of all the problems. The signature seems to be generated by this file: https://www.foxesscloud.com/js/signature.js, which does use a wasm file from here: https://www.foxesscloud.com/js/signature.wasm

Without much more reading on wasm and how it works, I'm hitting a bit of a wall. I also don't know python well enough to know if the wasm can be used with it.

Hopefully, this will help someone get a little further.

[johannessteu]

How the signature itself is generated is described in their API. I also posted it already here: https://github.com/macxq/foxess-ha/issues/206#issuecomment-1864124756

The main issue here is that you do need a secret/key to generate the very first call to authenticate. Not sure if we're able to 1) find a token everyone could use 2) this is a legal think at all to bypass their protections

[MartinBlackburn]

With that official API being limited to 20 calls a day, I was wondering how their website works

Their signature header differs and doesn't need an API key... It looks to be built up of two parts (begin_signature and end_signature)

I'm looking at the JS files and network traffic, so see what I can work out

[johannessteu]

Couldn't they have API-Keys that can bypass this limit?

[Golempl]

Website added signature and timestamp. Simple method of authentication stoped working because they check is signature match timestamp. To find out method to generate signature need spend some time to decompile and analyze JS and WASM components of webpage. Can reverse enginner it, however it may not be permanent because they may change it anytime they want. Webpage is using unlimited version of API for providing data. Let's hope manufacturer understand customers need and won't cripple functionality after product is sold. This change need be reverted or API needs remove limitations.

[canton7]

I have requested numerous time from the foxess support to provide data and address list for the sensors for rs485 protocol - they have never replied to me.

@snaiperr We have all of this figured out at https://github.com/nathanmarlor/foxess_modbus. See the wiki for the protocol docs.

[Golempl]

I have workaround. But this is ridiculous way, running separate VM which keeps chrome running and refresh webpage with result saved to location available for Linux VM. That's huge waste of resources.

[canton7]

It looks like the signature's been figured out: https://github.com/TonyM1958/FoxESS-Cloud/issues/3 . It also looks like FoxESS are reverting the change shortly, followed by a migration period to the new API.

[macxq]

@MartinBlackburn @Golempl indeed, heres decoded to c version of signature.wasm
I have used wasm-decompile. Looks quite complicated and not so easy to translate to python 🤦‍♂️

@macxq Note that end_signature doesn't seem to be used (it's called from the js, but the result is discarded). Most of begin_signature is just an implementation of MD5 (see my link above for the very simple Python equivalent). The only bit we're unsure of is the "5245784" which is appended to the MD5 -- it appears to be a constant (see the other thread I linked), and using a constant appears to work...

[johannessteu]

So yeah, i was actually able to update my scripts! I can fetch data again. This is what works our for me, written in go lang

Basically you need to set all of those headers and compute the sign string as shown here. Easiest way to reproduce this is to go to the foxess site, search for the login request and then try to replicate the signature sent there. On login token is always an empty string. The token you get back on login is then used for all other requests.

func SignRequest(r *http.Request, token string) *http.Request {
    lang := "en"
    path := r.URL.Path
    timestamp := time.Now().UnixMilli()
    str := fmt.Sprintf("%s\\r\\n%s\\r\\n%s\\r\\n%d", path, token, lang, timestamp)

    hash := md5.Sum([]byte(str))
    signature := fmt.Sprintf("%x.5245784", hash)

    r.Header.Set("User-Agent'", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36")
    r.Header.Set("Token", token)
    r.Header.Set("Timezone", "Europe/Berlin")
    r.Header.Set("Lang", lang)
    r.Header.Set("Timestamp", fmt.Sprintf("%d", timestamp))
    r.Header.Set("Content-Type", "application/json")
    r.Header.Set("Signature", signature)

    return r
}

So can you use Foxess in Homeassistant again? Or what does this mean?

[johannessteu]

I don't use the Homeassistant at all. I hacked a small box for my parents for christmas. It shows them the current status of their usage. Therefore i do have some custom scripts to get the actual data.

But for this code base it should be rather easy to upgrade i'd say. Those places https://github.com/macxq/foxess-ha/blob/main/custom_components/foxess/sensor.py#L128

needs to be updated. @macxq it might be a good idea to have a convenient signHeader method here as well that could be re-used in all places.

[Golempl]

Example of fetch data using bash script, can't be easier:

!/bin/bash

signatureGen() { local token="$1" local path="/c/v0/plant/earnings/all" timestamp=$(date +%s%3N) local str="${path}\r\n${token}\r\nen\r\n${timestamp}" local hash=$(echo -n "$str" | md5sum | cut -d ' ' -f1) signature="${hash}.5245784" }

token=cat /tmp/token.txt signatureGen "$token"

curl 'https://www.foxesscloud.com/c/v0/plant/earnings/all' -H 'contenttype: application/json' -H 'lang: en' -H "signature: $signature" -H "timestamp: $timestamp" -H "token: $token"

You need provide token, but nothing changed here

[MartinBlackburn]

The problem will be if that unknown number at the end of the signature changes: "5245784" While it looks like we are all getting the same now, it might change at some point without warning and break all over again

[manuelsirianni]

Tomorrow they will restore the functionality and give the time to create a new method.

Wait for some news..

Just a quick update for this thread, I realise the old cloud API is currently working again, but FoxESS have said this is time limited and will be discontinued; going forward they will only be supporting the new Foxess OpenAPI.

With support from @TonyM1958 I have modified / re-written this integration to use the new Foxess OpenAPI to allow existing cloud installations to keep working - Tony is continuing to work with the FoxESS R&D team to process outstanding issues.

The FoxESS OpenAPI is up and running but still under development and changes may occur, but the better news is that I already have a modified version of this integration working reliably and running against it.

There are many changes in the code to support this but from a users perspective it requires only minimal work to make the re-worked code run, it needs the Inverter Serial number and apiKey (see note below in API access) added to the platform config in configuration.yaml and after that it will respect the existing entity naming convention - all existing sensors will continue to populate as before but from the OpenAPI.

The new OpenAPI provides more information and so I have added the following sensors -

• sensor.foxess_residual_energy - this is the remaining residual energy in the battery kWh reported by the system BMS.
• sensor.foxess_bat_minsoc - the MinSoC setting of your system
• sensor.foxess_bat_minsocongrid - the MinSoC on Grid setting of your system

Sadly some extended attributes of the sensor.foxess_inverter have needed to be removed (Country, Country Code and Address) but I suspect many users do not use / or are even aware of these.

Open API Access and Limits The OpenAPI access is limited and must have a personal_api_key to operate, each user can generate their own personal_api_key in their own user profile at the FoxESS cloud - the number of API calls are limited to 1,440 calls per day, and when used up the OpenAPI will stop responding to requests.

This sounds like a reasonable number of calls, however multiple API calls have to be made on each scan to gain the complete dataset.

To manage this I have added code to pace the number of API calls that are made, currently it is getting all real time sensor information every 5 minutes (as now , and in-line with the datalogger update frequency), the report information that provides the current 'daily' figures for Feedin, Generation, GridConsumption, Battery Charge, Battery Discharge and Load, and the Energy Generated (todays yield) and the battery settings are read every 15 minutes.

As it stands the integration is using approximately 40 API calls an hour (960 a day and well within the 1,440), however there are some outstanding requests on FoxESS R&D that could reduce this further and hopefully in future allow faster updates.

It also fixes a few bugs and the deprecation warning errors that HA 2024.x is generating https://github.com/macxq/foxess-ha/issues/211

@macxq - not sure how to proceed with this?, I could send PR's but the code changes are extensive and the OpenAPI still subject to change, plus in the early days there will be a need for beta testing and user support - adding me as a collaborator to your repo would allow me to respond to that?. My code is in this fork https://github.com/FozzieUK/foxess-ha - if you would like to review it. Just for information for now I have a boolean in the code (TRY_OLD_CLOUD_API) that will fall back on the old cloud interface should the OpenAPI fail. It is set to False as default as the OpenAPI has been quite stable.

Please don't openly use the forked repository code yet as it is still under test and change, hence I can't respond to any PR's or provide support at this stage.

[FozzieUK]

@macxq Thanks for the add, I will add all changes into a testing branch for now 👍

[craigmcfly]

This seems to have reared its ugly head again. Stopped as of about 04:00 GMT.

[FozzieUK]

Yep this took everyone by surprise 😒 i'm on it now, the OpenAPI version is written and awaiting release.

@macxq - I've raised the PR to release the OpenAPI version, be grateful if you could review please 👍

[snaiperr]

@FozzieUK is it possible to use standard web version instead this unstable api ? i mean is not it easier to adopt it to standard web version ? now it's not possible to generate api key since error 500... looks so bad..

[FozzieUK]

@snaiperr the openAPI is actually working fine, but only if you already have a personal_api_key - FoxESS have been made aware of the problems and in the short term have to either get the old cloud access working, or get the request personal_api_key working - in the medium term the only access we will have is via the openapi.

[craigmcfly]

It's alive again! Much obliged.

Here still no values… How to fix?

Hi All. I have a problem with new integration. My instance of Home Assistance is running on dedicated platform with tailored made linux distribution and I have a problem with too many established connection opened by foxess integration. The system do not automatically close it so after couple of hours system freeze. With last integration (before API included) I have to change "Connection" type to Closed in two places in phyton code. Can you help me what can I change in updated version to close connection after single session of reading parameters?
