MMM-Hoymiles-Wifi

[schris88]

Hello, as I got into some PV lately I found no module to display the output of my solar panels, the new Hoymiles inverters with integrated wifi are not supported by OpenDTU or Ahoy because they no longer send via 2,4Ghz or Sub-1G.

This is a quick hacked solution for the issue, it uses the python library hoymiles-wifi to get the inverter data via protobuf from the connected inverter in your home network, then it renders 3 values as gauge and text with plotly

It´s working and looks okay, not much configuration right now, you have to set your inverter ip in the hoymiles_data.py and add the config to display the html.

Maybe someone sees this and finds it usefull, if there is any interest in the community I can work on this some more

@schris88 Nice :-) Don’t forget to add it to the module list: https://github.com/MagicMirrorOrg/MagicMirror/wiki/3rd-party-modules

Hi there,

I am using hoymiles-wifi myself and am curious on how it looks on the MagicMirror.
Very nice initiative !!

Trying to get your module working, but no luck till now.
I will open some Issues for you to have a look at.

Best regards,

E.J.

@evroom We will make this work, great input, there is so many possibilities what and how to display the data.
Im thinking about feeding a free tier mongodb or some local docker db for long time charts.

It is working now.
I see it displayed on the MagicMirror.
Due to no sunshine I cannot check actual values, but that is for later.

Hi,
I am using
HMS-800W-2T
I have done your installation steps but there is no output on my MagicMirror.
The source http://127.0.0.1:5000 is correct?
What can I try?
Have you any idea what could be wrong?

You have to edit
~/MagicMirror/modules/MMM-Hoymiles-Wifi/hoymiles_data.py
Change this line to the address of your DTU:
dtu = DTU("192.168.178.114")

And I had to change

 width: "288px",
 height: "360px",

in the ~/MagicMirror/config/config.js file.

This is my config:

{
  module: "MMM-Hoymiles-Wifi",
  header: "MMM-Hoymiles-Wifi",
  disabled: false,
  position: "top_left",
  config: {
    width: "288px",
    height: "360px",
    updateInterval: 60000, // in milli seconds
    frames : [
      { src: 'http://127.0.0.1:5000' },
    ]
  },
},

Just FYI.

I am currently busy making some changes to the module.
As there is no sunshine due to the current weather conditions, it is a bit difficult to have real measurements.
Trying to add a test using a JSON dataset.
Hope to be able to present it a.s.a.p.

Change this line to the address of your DTU:
dtu = DTU(“192.168.178.114”)

sounds like a new config parm so you don’t have to edit the file
(pass as a parameter on /hoymiles_data.py start)

Exactly!

I did change hoymiles_data.py to be able to refrain from hard-coding it:
python hoymiles_data.py --dtu_ip_address 192.168.178.114--debug
The next thing would be to pass the parameter(s) from the configuration (to be coded in the MMM-Hoymiles-Wifi.js file).

As I never made a module myself, I would need to find out how.

Any suggestions are much appreciated!
