Hi there,

I made some major changes to the code and hopefully did all the GitHub stuff correct in order to allow persons interested to give it a (new) try.

https://github.com/schris88/MMM-Hoymiles-Wifi

There is still a lot to do (see ‘TODO’ in the README file), but I think the basis provided by Christian (@schris88) has been strengthened.

Best regards,

E.J.

@schris88

Christian,

This is on the TODO list:
change pv_data to dtu date for combined output of inverter

But I do not really understand what you mean by it.
Do you mean combined output of 2 panels iso just 1 ?

Please elaborate.

E.J.

[schris88]

@evroom Hi there, maybe you can confirm, if the inverter has multiple inputs there seems to be an array of pv_data objects in the json (as seen in the test.json you pushed)

so the meter should combine all pv data power to have the total, right.
But we dont need to do that by hand because the combined value should be in dtu_power already, you can get rid of all the try except.

I just didnt change it in the beginning because for inverters with only one input it makes no difference because its pv_data power and dtu_power is always the same value.

[evroom]

@schris88

First of all, those are details I need to have a look at now that the basis is there.
Perhaps there are other values and queries that make sense and that I can use. Like dtu_power and dtu_daily_energy.
Also saving some data to not have counters showing 0 when the invertor is inactive needs to be implemented.
During testing I found out that the pv_data for port 1 and 2 were different sometimes and that is why I needed to add those checks.
And they can never hurt. Better to be safe than sorry.
Furthermore, when you have only 1 panel connected, it is needed anyway.

[evroom]

@schris88

Just FYI, I declare(d) more parameters than really necessary and actually used, in order to allow for more counters to display.
For example a gauge for each panel; more details on the energy production of each panel; etc.
I will make a remark about this in the code.

[schris88]

@evroom That sounds good, but we should loop through the pv_data objects and display each as a graph. In the end, there could be a config setting like detailed: true to activate the display of all pv_data objects as individual graphs. If set to false, we could display a single graph with the total power.

There are Hoymiles inverters with 6 inputs, and adding 6 × 6 to 8 variables can quickly add up. This might not be an issue for us, but it’s worth considering if the module should be as generic as possible.

Sorry I´m a IT-Consultant who, sometimes it breaks through :D

[schris88]

@schris88 Recently worked on it a bit and added a second branch with local mongodb to save and display max power, Im planning to use the db entries to display a history chart

Hallo,
ich bin reltiv neu hier und versuche gerade das modul zu installieren.

Ich habe soweit alles nach Anleitung gemacht, aber wenn ich ./HoymilesWifi.sh starte kommt immer folgende Meldung:

 * Serving Flask app 'hoymiles_data'
 * Debug mode: off
Address already in use
Port 5000 is in use by another program. Either identify and stop that program, or start the server with a different port.

Was mache ich falsch? Der port ist angeblich durch pthon belegt …

Danke und Grüße

Florian

[evroom]

@Jose1701

Try this to find out what is using port 5000:

sudo netstat -apln | grep -w 5000

And did you update the bash program?
https://github.com/schris88/MMM-Hoymiles-Wifi?tab=readme-ov-file#enter-dtu-ip-address-of-dtu

[Jose1701]

@evroom
Thanks for the quick answer.

I inserted the IP of the dtu.

Portscan is:

@Jose1701

This command should give more information on the PID found:

ps -Flww -p

E.g.

ps -Flww -p 64879

Perhaps there are easier ways, but this should do.

[Jose1701]

@evroom

Seems that this is hoymiles …?

[evroom]

@Jose1701

Yes, so an instance is already running.
You added it to pm2 too?

pm2 status

If yes, then you do not need to run it manually.
If no, then kill the (p)pid.

sudo kill -9 [ppid]

[Jose1701]

@evroom

Well, I’ve done that now. At the moment it is night so I can’t see any output.
Will see if it works tomorrow …

Thank you. I will post if it runs then.

[Jose1701]

Can’t get it to work.

I don’t know what I’m doing wrong…

Now, Portscan ist about that:

tcp        0      0 127.0.0.1:5000          0.0.0.0:*               LISTEN      1139/python

@Jose1701

First I would disable the module:

$ vi ~/MagicMirror/config/config.js

    module: "MMM-Hoymiles-Wifi",
    disabled: true,

$ pm2 restart MagicMirror

I build this command to try to get more info on port 5000:

$ for pid in `lsof -i :5000 | grep -v 'PID' | awk '{print $2}' | sort -u`; do echo $pid; ps -Flww -p  $pid; done

Hopefully the Forum tool does not change it.

Furthermore please verify and supply the following data:

$ cd /home/admin/MagicMirror/modules/MMM-Hoymiles-Wifi

Check path:

$ which hoymiles-wifi
$ echo $PATH

Check if the path is in the PATH.
If not, do (using the path from ‘which’):

$ export PATH=$PATH:/home/admin/.local/bin

Check config.js:

$ grep ':5000' ~/MagicMirror/config/config.js

Expected is:

{ src: 'http://127.0.0.1:5000' },

Check HoymilesWifi.sh:

$ grep 'dtu_ip_address' HoymilesWifi.sh

Expected is your DTU IP address, for example:

python hoymiles_data.py --dtu_ip_address 192.168.178.50 --max 800

Test run (hoymiles-wifi):

$ hoymiles-wifi --host 192.168.178.50  identify-inverters

Expected is a response.

Test run (HoymilesWifi.sh)

$ ./HoymilesWifi.sh

Expected is:

* Serving Flask app 'hoymiles_data'
* Debug mode: off
INFO:werkzeug:WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.
* Running on http://127.0.0.1:5000
INFO:werkzeug:Press CTRL+C to quit

If you wait a bit some more output is shown.

If it works, then I would suggest to stop the ./HoymilesWifi.sh command and do:

$ cd /home/admin/MagicMirror/modules/MMM-Hoymiles-Wifi
$ pm2 start HoymilesWifi.sh
$ pm2 save

$ pm2 status HoymilesWifi

$ pm2 logs HoymilesWifi --lines 10

If everything is okay, the enable the module again:

$ vi ~/MagicMirror/config/config.js

    module: "MMM-Hoymiles-Wifi",
    disabled: false,

$ pm2 restart MagicMirror

[evroom]

To be honest, for me the MM does not display anything.
Although it is dark, I still expected the graphic with 0 or so.
Or I have to wait a bit longer.

I used
https://github.com/schris88/MMM-Hoymiles-Wifi/
and all the above is correct and running.

A year ago I made a fork and made some changes, of which I think are present in the schris88 version as well.

https://github.com/evroom/MMM-Hoymiles-Wifi/
I will give this one a try when I have time.

PS: it seems that when the microinverter is off-line, you will not see anything. Need to wait for it to be active again.

[Jose1701]

@evroom said in MMM-Hoymiles-Wifi:

$ grep ‘dtu_ip_address’ HoymilesWifi.sh

Until that line everything is ok. After that it says:

grep: HoymilesWifi.sh: No such file or directory
