@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 @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

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.

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.
