Apsystems API down

Since Saturday the Apsystems unofficial REST getpowerinfo service has been down.

I have tried to write them to ask if this is intentional or not. They never respond to end user mail it seems.

Is anyone experiencing the same and is there an alternative way to get live data out of the Apsystems inverters?

Yes i have the same problem. I am make workaround and download date directly from ecu.
Here’s a snippet of code that does this:

self.url_power = f'http://{self.ecuip}/index.php/realtimedata/old_power_graph'
def get_data(self, time_stamp: datetime = datetime.today()) -> pd.DataFrame:

    data = {
        'date': time_stamp.strftime("%Y-%m-%d")

    response = requests.post(self.url_power, headers=self.headers, data=data)

    if response.status_code != 200:
        except Exception as e:
            msg = (
                'Bad status code! Response content = {}. Exception = {}'
                    .format(response.content, e))
            raise e.__class__(msg)
    ans = {}
    energy = 0
    time_start_s = 0
    res = response.json()
    for record in res['power']:

        time_actual = pd.Timestamp.fromtimestamp(record["time"]/1000)  # ,tz="Europe/Warsaw",tz="Europe/Warsaw"
        power =  record["each_system_power"]

        time_pass = time_actual.timestamp() - time_start_s
        if time_start_s == 0:
            time_pass = 300
        time_start_s = time_actual.timestamp()
        energy += power * time_pass / 3600
        ans[time_actual.round("5min")] = (power, energy)
    time_actual += pd.Timedelta(minutes=5)
    ans[time_actual.round("5min")] = (0, energy)
    return ans

However that seems not to work for me.
Did you configure the ECU somehow to enable this?

No didn’t configure the ECU in any way. What type the ECU do you have?
I have this ECU:

Hi All,

First forum where I see same issue. Looks like the API does not respond for some days now.
On my side this does not work as I have a ECU-R requiring an authentication.
I think this direct access only works with ECU-C.

I found artical how to read from ecu-r

I write some code that allow download data from https://apsystemsema.com/

Thank you so much for the input.

I have used this code in combonation with what I had before and am now back to uploading data every 5 min.

If there is an interest I am happy to share the result

Actually now this is also down.

It has been down for the last week so I assume it is not coming back.

The API seems still to be available but returns error 500 at every call.

Does anyone have an idea as to how to fix this?

(I assume what people do is to analyse how the Web client or the App retrieves the needed information. But I am not a network monitoring expert.)
