a new family-member has joined: MMM-FroniusSolar5.

This adds the functionality to monitor and visualize solar energy data from multiple Fronius inverters simultaneously.

See module for more information. If you have 2 or more Fronius Inverters running, give it a try.

I am not completely sure if it works 100% stable since I have only 1 inverter. If you discover any problems open an issue.

please check in your config.js the radius value. It should be Radius: 50,. In the beginning when I released the module there was a copy+paste error. The radius was 80.

If you want to enlarge everything as I see the gauge radius on your mirror you need do go deeper into the MMM-FroniusSolar2.js file:

• Adjust text size in // Main Text | // Sub Text area.
• Modify gauge coordinates here:

        const positions = {
            PV: { x: 75, y: 75 },
            Grid: { x: 225, y: 75 },
            Akku: { x: 75, y: 225 },
            House: { x: 225, y: 225 }
        };

• If everything is bigger modify also the view box:

          svg.setAttribute("viewBox", "0 -20 300 350"); // Adjusted viewBox to fix label cutoff

The view box part is really annoying. It does not what you expect (The gauges do not have 50px. In fact everything is scaled in the viewbox). If you have a working status which might be useful for others, please share. I cannot support here since it is really tricky.

Don’t know what I did but it’s all working now - only problem is all the circles are bunched up.
Also, how can I enlarge and bold the fonts

To go to the chat and post a mimimi only is not that helpful to find the error. Use the log-version above then you‘ll find your error.

Read the doc, install the latest module, enter a correct ip and activate the api in your inverter. I cannot see any more I can do here. At least post an error log or somerhing helpful.

This will create a lot of log entry. So only use this temporary. If you see any errors you can’t solve, please send me the logs.

Later use pm2 flush to clear the logs. The log-file size will increase with this version quite fast.

Hi,
Thanks for your response - I am attempting to install Fronius Solar 2 and have commented out the line in node-helper.js as advised in a previous post ( //const fetch = require(“node-fetch”);) and ran MM.

It all loaded OK with no errors but it doesn’t show up on the dashboard, doesn’t even say loading. IP address is correct.

I’ve updated the node _helper.js.

//const fetch = require("node-fetch");

If some has trouble it can be reactivated. Maybe I hab installed node_helper in the past manually. I don’t remember. Until now I had no errors from that. But yes, it woks well without this line.

Hello Chris
FYI.
They remove node fetch from the magic mirror package on the last release as we drop back to the integrated fetch that’s provided in node and in the electron browser unfortunately that breaks a bunch of modules.

Just remove the the line const fetch = require(“fetch”); in the file node-helper.js in the module’s directory.

I Have removed the line, and now it works

const fetch = require(‘node-fetch’)

you can comment out that line and the fetch syntax is the same

• you’re using MMM-FroniusSolar3 from me (ChrisF1976 on GitHub).
• On your Fronius Symo GEN24 you activated the SolarApi.
• In the config.js you used the correct IP

I just started it on my mirror and it works without any problems. I also deleted it completely and reinstalled it with “git clone…”.

So the only reason I can imagine is, that there is a collision in the node_helper.js. I used only “SET_CONFIG” to data exchange. Maybe other modules use this, too. I had a lot of collisions already :-)

Go to the node_helper.js and replace:

    socketNotificationReceived: function (notification, payload) {
        if (notification === "Solar3_SET_CONFIG") { //Solar3_ added to avoid collision with other modules

Then go to the MMM-FroniusSolar3.js and replace:

    start: function () {
        this.solarData = null;
        this.solarSOC = null;
        console.log("[MMM-FroniusSolar] Sending configuration to node_helper...");
        this.sendSocketNotification("Solar3_SET_CONFIG", this.config); // Send configuration to node_helper with more specific name
        this.scheduleUpdate();
    },

I this helps, please tell me. Then I’ll update it in general also for the other modules.

If it doesn’t help, please look into the logs (for example with pm2 log mm) and also in logs of electron (I think ctrl+I was the command). I’m running a separate instance on server mode with the port 8081 and a separate config2 to find those errors. I hope you can find the error!

Thank you

Which version do you try to use?

Chris.
