MMM-FroniusSolar family modules

[alfi153]

@chrisfr1976
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

@chrisfr1976

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

[chrisfr1976]

@sdetweil
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.

[chrisfr1976]

@waynerob11
Please send the error massage that you receive. I want to help you!

@chrisfr1976

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.

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,
is this issue solved now?

[TomOMaley]

Hi, does meanwhil one of your fronius modules work whithout Problems? Tried the second one but no display at all. What changes in the config etc. are still necessary?
Regards Walter

@TomOMaley
All modules work without any problems on my mirror. No errors, nothing in the logs and it gets data every 2 seconds.

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.

@chrisfr1976 Dear Chris, I apologize for my unqualified question. Regards

Hi Chris,

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
