MMM-FroniusSolar family modules

chrisfr1976

Hi,

i was working the last days on a module to get rid of the last iframes on my mirror. These modules can all visualize solar energy data from a Fronius solar system using SVG magic :)

MMM-FroniusSolar: Best for simple setups prioritizing clarity and minimalism.
MMM-FroniusSolar2: Suitable for scenarios requiring visual feedback on power flows (e.g., monitoring dynamic energy consumption).
MMM-FroniusSolar3: Ideal for larger or customizable displays where scalability is important.

If you do not have a FroniusPV but your system has an API it should be not much work to adjust the node_helper file.

All in a column:
MMM-FroniusSolar

Hi,

i found a small bug. At this moment you need to change your inverter-IP in the node_helper.js file.

I‘ll fix this to a config entry this weekend.

chrisfr1976

Fixed. IP can now be defined in the config.js:

InverterIP: "<yourInverterIP>",

Hello,

I’ve added a quite special module to the “family” which is exact what I need. Maybe someone else hat also a PV on the roof controlled by the Fronius inverter and in addition a mini-PV system measuring with a Shelly-device. I have exactly that case in my house :-)

So, that’s it: MMM-FroniusSolar4

Added Shelly device in the monitoring:

MMM-FroniusSolar4

There is a small flickering effect with the text labels. SVG doesn’t like text with icons inside that much. I have no more ideas how to fix this (I tried a lot). But it is not really annoying me.

One hint: the label text must be modified in the js-file in this part of the code:

        svg.appendChild(createGauge( "Grid", this.config.icons.P_Grid, "top", .............));
        svg.appendChild(createGauge( "Akku", this.config.icons.P_Akku, "bottom", ................));
        svg.appendChild(createGauge( "", this.config.icons.P_Load, "middle",..................));
	svg.appendChild(createGauge( "PV Mini", this.config.icons.P_Shelly, "bottom", ...............));

The "" is the house in the middle :)

Hi. the module looks very good.
I installed the Fronius3. But my mirror only shows loading. The ip is correct. On an other mirror I use energy monitor and this works.
Any idea what I make wrong

Hello,
the node_helper.js is the same for module 1,2 and 3. If one of them is not running there must be a config error. Maybe my mistake in the readme. Check what the console messages and/or pm2 logs tell and send me the result. I‘ll check parallel the documentation.

Hello.
On the other Mirror I use MMM-Fronius2 from deg0nz. These model get information from my Gen24. But your module shows: loading. Is there anything to change in the Gen24 settings

chrisfr1976

@alfi153 Hi, my module is working complete different. I don‘t know the other node_helper. The MMM-FroniusSolar 1-3 use the same node_helper. Version 4 is again different. For inverter settings nothing special is necessary. Is the ip configured corretly?

Which version do you try to use?

Chris.

@chrisfr1976
I try to use Version 3.
The ip is correct
i have activated the API on my Fronius Gen24
is it possible to get any Log file?

@chrisfr1976
i fixed it
i had to install node-fetch

Thank you

@alfi153 Hi,
I think I’ve misunderstood this conversation a little bit.

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!

@alfi153 Okay, there was a delay in your message. Glad to her that everything is okay now. If you need any assistance please let me know:)

@alfi153 @chrisfr1976 the current versions of nodejs since 18 have fetch built in. if the module does

const fetch = require(‘node-fetch’)

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

@chrisfr1976 everyone with reputation below 2 has every post reviewed (by me) before going live. sometimes i sleep! or do other things. lol

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

Tried to install 2 and 3 on an RPI 3B+ running 64
bookworm - will not even load and throws a .js error - IP address configured and did copy and paste for the config.js - mm just stalls

Hi,

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.

Please send the error massage that you receive. I want to help you!

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.
