Wiser Energy SOAP communication

[Breina]

I've installed a ER31800 which receives data from powertags and sends it over TLS to a Schneider server. It also broadcast SOAP discovery requests. I'm interested in getting energy data out of my device locally through SOAP.

Until now I've only managed to get some metadata (through 

http://schemas.xmlsoap.org/ws/2004/09/transfer/Get) such as manufacturer and serialnumber, but I have yet to find an endpoint to get the actual data. I have tried some ISXCentral WSDL's, but they don't resolve. I've also tried setting up a connection through TLS, but it seems the device only accepts Schneider CA's. I haven't asked, but I doubt I'll be able to  convince Wiser Cloud Services Root CA to sign my certificate.

Can anyone please point me into the right direction? I'm specifically trying to find a WSDL for the service running on my ER31800.

There is also a serial communication port on it, if its spec is known, that could help as a backup solution.

EDIT: Oh, I should mention, I'm specifically looking to integrate it into HomeAssistant's energy monitoring system. They specifically forbid web scraping, and scraping https://app.schneider-electric.com/wiser-energy/ is not a great solution anyway.

There is also https://exchange.se.com/devportal/api/wiser-energy-api, but they charge $15/month, which is a ridiculous price for my own data. I'd like to run the system disconnected from internet anyway.

Hi,

Thanks for your Post !

The ER31800 gateway is a piece of the Wiser Energy system.

As such the gateway is programmed for a secure connectivity via the Wiser Cloud. There is no local interface designed to get the data locally.

The local serial port can be used to connect a EM5 device. It is not a generic interface.

As mentioned the data are available in the exchange service. Exchange provided formatted datas, including historical in a stable interface.

For local connection, PowerTag Link (A9XMWD20 or A9XMWD100) should be used. Modbus interface is available for sure.

Maybe some more interface. Please contact Digital Energy phone support for more info.

Cheers
