MMM-SunnyPortal Solar Module

probably a developer problem… don’t know the module at all

Hi,

It seems that the sunnyportal website is very picky about which user-agent is trying to connect to their web server.

I just changed the user-agent string on line 61 of the file node_helper.js
from

‘User-Agent’: ‘Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:71.0) Gecko/20100101 Firefox/71.0’,

to

‘User-Agent’: ‘Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:77.0) Gecko/20100101 Firefox/77.0’,

And now I am able to login again.

I will try to work out some better code to prevent this from happening in the future.

Can somebody else verify if this solution works?

Regards,

Thanks for this great module. I have a problem on the loading.

So if I read correctly, I see that Buffer() is depreciate.
But It’s also write something strange with the certificate. In the mm-out.log I see more information:

0|mm       | [2020-06-22 17:26:43.303] [LOG]    SocketNotification START_SUNNYPORTAL received for the first time...setting updateInterval to 900000ms

What can I do to resolve this case?
I already try to uninstall and re-install all, with npm install or ./install_deps.sh or the 3 npm install request / flow / chart but it doesn’t works.

Any idea?

Thanks for your help

@Snake-Darkangel

Thanks to hervidero the code has been altered so that it ignores the provided SSL Certificate.

Hervidero also made the charts a little bit better and wrote some code to make sure you can’t set an updateInterval < 15 minutes.

This release also includes the User-Agent change suggested in the previous comment

@linuxtuxie
Hello , i try to run the SunnyPortal module, but still no result. I´ve reinstalled the Pi severl times , down to a fresh image with no other modules, but i get only the loading view. thats all.

Any idea what i have to do ?

error message from PM2.log
Login Failed, no redirect to Dashboard or UserProfile/FixedPages/HoManEnergyRedesign.aspx

linuxtuxie

Hi icemanmw,

It seems that your installation is redirecting you to the following page: /FixedPages/HoManEnergyRedesign.aspx instead of the ones we already know of (DASHBOARD_URL & USERPROFILE_URL )

In to code we are checking if the returned HTTP redirect matches the DASHBOARD_URL or USERPROFILE_URL

You could try to use the below code in the node_helper.js script to add this page

Add the HOMAN_URL variable at line 21
var HOMAN_URL = ‘/FixedPages/HoManEnergyRedesign.aspx’;
Change the code starting from line 99
// Hack to check for login. Should forward to dashboard.
if(httpResponse.headers.location && httpResponse.headers.location === DASHBOARD_URL) {
console.log(“SUCCESSFULLY LOGGED IN TO DASHBOARD”);
callback(err, jar);
} else if(httpResponse.headers.location && httpResponse.headers.location === USERPROFILE_URL) {
console.log(“SUCCESSFULLY LOGGED IN TO USERPROFILE”);
callback(err, jar);
} else if(httpResponse.headers.location && httpResponse.headers.location === HOMAN_URL) {
console.log(“SUCCESSFULLY LOGGED IN TO HOMAN”);
callback(err, jar);
} else {
console.log("Login Failed, no redirect to Dashboard, UserProfile or homan "+ httpResponse.headers.location);
callback(new Error(‘Login Failed, no redirect to Dashboard, UserProfile or homan’));
}

Can you let us know the results?

Hi linuxtuxie,
sorry fore my late response . I was a few days in Austria.
Nevertheless i tried today your proposal and it looks much better. Now i see that :

I’ve the same issue. I try the update in the code, adding the httpResponse.headers.location in the log => it’s “undefined”
(and http result : 200.)

With the new version of the module, I’ve this log:

[2020-11-23 12:26:02.231] [LOG]    Login Failed, no redirect to any of the known url's /FixedPages/Dashboard.aspx, /Templates/UserProfile.aspx, /FixedPages/HoManEnergyRedesign.aspx
[2020-11-23 12:26:02.233] [LOG]    You are being redirected to the yet unkown url: undefined

In my browser I see on the homepage a pop-up for a new SMA application. Maybe that can generate another URL ? I tried to cancel it to see if it’s the problem but … nope :(

Still looking for a solution.

Hi Snake-Darkangel,

Did you use the latest code listed at https://github.com/linuxtuxie/MMM-SunnyPortal ?

More specifically the piece of code listed in the file node_helper.js is important. SunnyPortal seems to be very picky when it comes to the browser which makes a connection to there website. I recently updated the user-agent to the latest Firefox version as shown below:

headers : {
// We need to simulate a Browser which the SunnyPortal accepts…here I am Using Firefox 82.0.3 (64-bit) for Windows
‘User-Agent’: ‘Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:82.0) Gecko/20100101 Firefox/82.0’,
},

User SkyFocusNL even used another user-agent to get things working
https://forum.magicmirror.builders/topic/14019/mmm-sunnyportal-not-loading/3
maybe you can give that solution a try and provide us some feedback ?

Linuxtuxie
