SMA Sensor on Home Assistant

[ekkesa]

Hi,

This looks very awesome - I have been using webscaper up until now, but this will be much cleaner. Unfortunately, I get errors connection errors (See below). The IP address it tries to connect to is correct, I also verified the user password on the Sunny Explorer software.

2019-10-04 00:25:29 ERROR (MainThread) [pysma] Could not start session, Could not connect to SMA at http://192.168.0.3 (timeout), got {'err': 'Could not connect to SMA at http://192.168.0.3 (timeout)'}

I have enabled all external communication on the module with their default values - Please see snippet of the settings - https://imgur.com/a/7he7joj

Your assistance will be much appreciated!

Can you do a portscan (zenmap - all tcp ports) on the IP of the inverter? Can you see port 80 or 443 is open?

Hi,

I did scans against it, and it seems the ports are filtered.

Port 502 shows open with an mbap service running.

I checked the Sunny Explorer software again, but do not see any option to enable such services. The only option I see is the once in the image I posted earlier.

Any idea why the ports will seem filtered.

Thank you for getting back to me...

What url do you point your webscraper to?

[ekkesa]

The URL is: https://www.sunnyportal.com/Templates/PublicPage.aspx?page={{UNIQUE ID}}

you need to access it on your local network using a web browser.

This library does not use sunnyportal.com

Hi,

Thank you for the quick reply - I gathered that much, but it doesn't seem to offer a web service running on the local device. Are there any special settings on should enable on the SMA to get this up? The unit was installed end 2016.

Sorry, no idea what options/configurations you get on these SB’s!

You could try the homeassistant forum/see if SMA some customer support
