MMM-Hoymiles-Wifi

Try this to find out what is using port 5000:

sudo netstat -apln | grep -w 5000

And did you update the bash program?

@evroom
Thanks for the quick answer.

I inserted the IP of the dtu.

Portscan is:

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.

Seems that this is hoymiles …?

@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.

@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

Jose1701

@evroom said in MMM-Hoymiles-Wifi:

$ hoymiles-wifi --host 192.168.178.50 identify-inverters

This works:

Identify-inverters Response:
{'1412a015f1e3': 'HMS-800W/1000W-2T'}

After that: ./HoymilesWifi.sh

 * 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.

@Jose1701 typo

 grep 'dtu_ip_address' Hoymiles-Wifi.sh

Jose1701

@sdetweil

Im getting this:


python hoymiles_data.py --dtu_ip_address 192.168.178.150 --max 800

sdetweil

@Jose1701 he just wanted to see the IP address the module was connecting to , which is hard coded in that line

evroom

@Jose1701

First of all, where I write

/home/admin/

please use

~/

(tilde sign)

And can you please send me:

cd ~/MagicMirror/modules/MMM-Hoymiles-Wifi
git branch
git remote -v

Every time you get that port in use error, run the long command to see what programs are using the port.
And of course do not use HoymilesWifi.sh when it is also active under pm2.

I am starting to wonder if the module works at all.
I finally got a picture, but it showed an error in it.

evroom

@Jose1701

You also might try this module:

https://github.com/CuddlyCow/MMM-HoymilesPVMonitor

I may give it a try myself.

Jose1701

@evroom

* master
origin  https://github.com/schris88/MMM-Hoymiles-Wifi (fetch)
origin  https://github.com/schris88/MMM-Hoymiles-Wifi (push)

I used the ~ symbol.

@evroom

Well I tried that but I’m to silly to install it.

@Jose1701

You installed that already, so no need to install it again.
Probably using:

python -m pip install -r requirements.txt --break-system-packages

The schris88 requirements.txt contains the hoymiles-wifi package.

Jose1701

@evroom

By unsing this, I get the following error:

python -m pip install -r requirements.txt --break-system-packages

Defaulting to user installation because normal site-packages is not writeable
