End of life FOP Portal

[sematuszewski]

Do you plan to adapt the integration to the new EOP platform?

Unfortunately, the old FOP platform is scheduled to be deactivated after April 20.

I noticed that the new platform uses bearer tokens for login, which complicates simple login.
I analyzed the new platform for extracting historical data from voltage for SEC meter.
I managed to use Selenium for this purpose and I can extract data to json file, but it is historical data.

I no longer own a SAJ inverter or hava an account, so sadly this repo will either die unless some takes over it.

If mine of this repository will not be maintained by new people (so far none for mine. I am advising to look into the following.

I applied to SAJ for a developer account and got access to the new API details, but without an AppID and secretkey the information is useless. A week after applying for an AppID I'm still waiting and have heard nothing.

I'm exploring the DNS poisoning and MQTT interception route instead.

Great news :)
Can you tell me where exactly you applied for access to the developer account?

I have quite good contact with support in Poland and it is possible that if I also applied for a developer account they would give me login details faster :)

You can log in to the following website and register an account for further assistance:
https://developer.saj-electric.com/fileCenter/index

After registering an account the API doc is visible. You're then supposed to apply for an AppID and secret key. They say that takes 1 business day. That's not been my experience.....

@walkjivefly, what kind of inverter do you have? Have you been able to get somewhere with MQTT? My inverter is sending data to my own MQTT server now, but nothing obvious comes out of it unfortunately. I found the project by paolosabatino. This is for an H1 and unfortunately does not work for my R5...

Yes, I'm getting data fine from an H1 3.6k using https://github.com/h3llrais3r/ha-saj-h1-mqtt which is a slightly updated version of the paolosabatini integration. It was a bit of a learning curve. There's more information about what I needed to do in paolosabatino/saj-mqtt-ha#4

I've still not had a reply to the application for an AppID and secretkey so I've given up on that approach.

Sorry to hear the MQTT integration doesn't work for an H5. I don't understand anywhere near enough about how it works to offer any helpful suggestions. In the discussion liked above is a link to a Telegram group which AFAIK is where the information about the SAJ MQTT protocol came from. There might be information in there about the H5.

Hello,

Is there anyone here besides me who still has the SAJ SEC module?

Currently, I am able to log into the new portal using a Selenium script and extract data in json from the portal sent by the SEC module.

Endpoint, which returns data in json after logging for the SEC module (endpoint is responsible for displaying historical data, but you can limit the query to the last updated value in the data)

https://eop.saj-electric.com/dev-api/api/v1/monitor/sec/getSECHistoryDataList?pageNo=1&pageSize=**1**&plantUid=**YOUR_PLANT_UID**&moduleSn=YOUR_SEC_MODULE_SN&chartDateType=1&chartDay=**YYYY-MM-DD**&appProjectName=elekeeper&clientDate=2025-04-21&lang=en&timeStamp=1745271622417&random=nn783v3WvsweM5PryFHatXKGkdhhhjw5&clientId=esolar-monitor-admin&signParams=pageNo,pageSize,plantUid,moduleSn,chartDateType,chartDay,appProjectName,clientDate,lang,timeStamp,random,clientId&signature=GA3F1BE42122FDB47BF941B6B4B881C5ACD04C767

pageSize - from 1 (last updated data from a specific date) to 1000 (all data from a specific date in a single json response, but the sec module sends data on average every 5 minutes [24*60/5=288 average updates per day], so in general, anything above 300 will pull all updates).

plantUid - unique plantUid

moduleSn - sec module serial number

chartDay - date in YYYY-MM-DD format, example: 2025-01-01 retrieves data from the first day of January 2025.

All other parameters are currently irrelevant, some take random values, I don't know yet what they are generated from, but in general tests have shown that specifying anything in them causes no change.

I can upload my test scripts to git if anyone would like to help customize them for use in HA.
I just want to say that they were written to simply work, they are not written to be “pretty” ;)

[erelke]

@sematuszewski Please share the script you wrote so we can move forward with it.

I'm exploring the DNS poisoning and MQTT interception route instead.

I have great news :) SAJ has accepted my developer account and I can generate AppID and secret keys.
They did it an hour ago, so I need to analyze how to use it at all.

[sematuszewski]

@sematuszewski Please share the script you wrote so we can move forward with it.

I'll try to upload it to my git today :)

[walkjivefly]

SAJ finally approved my application too.

[sematuszewski]

Now I guess I have to wait for the app to be accepted, because the endpoint API reports the error “{”code“:200014, ‘msg’: ”App_ID is disabled“}”. (https://developer.saj-electric.com/prod-api/open/api/access_token?appId={appId}&appSecret={appSecret})

Query to “https://pre-developer.saj-electric.com/prod-api/open/api/access_token?appId={appId}&appSecret={appSecret}” reports error 502

[thephantom]

I think this is the reason why I can no longer read data from my saj account. I get the message Setup failed, retrying: Expecting value: line 1 column 1 (char 0)
