So, here is my build…

Electrical cabinet:
Holds circuit brakers, patch pannel, network switches and NAS

How it should look:

My wife and daughter likes it.

And my test setup:

For now, I’m runnung it on VirtualBox running Raspbian like distro.
I have one Raspberry PI 3 runing Pihole and tor proxy for now.
I’ll add MagicMirror to that PI once I learn to fine tune MagicMirror and when my kids let me.

I never expected it to look so good!

Technical:
Rear is OSB board 12mm painted black
Glass is blue(ish) tinted 6mm thick
22" LED display, only VGA, working with RPI using adapter
Aluminium L profiles 20x10x2mm to hold glass in place
Dimensions are 205 cm tall, 33cm wide, 2 cm tick, heavy as f***.
Between glass and board there is black cloth. Behind glass it has texture like display.
On strong light, diplay is just visible because i taped black electrical tape to metal edges. And it slightly reflects light.

I tried that.

@Kereknjek said in MMM-ArduPort:

Now, when running

python arduport.py

I get this:

{"debug": "SerialPort shell started..."}
{"debug": "Waiting Ardunio to connect on port..."}
{"status": {"data": "connected", "name": "connect"}}
{"status": {"data": "starting", "name": "setup"}}
{"status": {"data": "started", "name": "setup"}}
{"sensor": {"data": "0.02", "name": "Baterija"}}
{"sensor": {"data": "-0.00", "name": "Struja"}}
{"sensor": {"data": "0.00", "name": "Solarno"}}
{"sensor": {"data": "-0.12", "name": "Panel"}}
{"sensor": {"data": "-0.00", "name": "Inverter"}}
{"sensor": {"data": "0.04", "name": "Baterija"}}
{"sensor": {"data": "-0.00", "name": "Struja"}}
{"sensor": {"data": "0.00", "name": "Solarno"}}

Well, I have abandoned ArduPort. Never got it to work. So I switched to json-feed.

It wasn’t easy for me because I had zero knowledge about http requests. But I got it working.

For anyone, with limited knowlege, like me, here is the code I’m sending from arduino ethernet server:

void sendjson(EthernetClient cl)
{
    // send a standard http response header
    cl.println("HTTP/1.0 200 OK");
    cl.println("Content-Type: application/json");
    cl.println("Connection: close");
    cl.println();
    // 
    cl.println("{"); // start of json data
    cl.print("\"Info\":\" ");
    if(y==true){cl.print("ERR COM");} // error in comunication
    if(y==false){
      if(inverterukljucen==1){
        cl.print("ON"); // system is on
        }
        else
        {
          cl.print("OFF"); // system is off i.e. no sun
        }
      }
    cl.println("\",");
    
    cl.print("\"Baterija\":\" "); // battery voltage
    cl.print(naponbaterije);
    cl.println(" V\",");

    cl.print("\"Struja\":\" "); // current going in or ouf trom battery
    cl.print(strujabaterije);
    cl.println(" A\",");

    cl.print("\"Proizvodnja\":\" "); // production of electricity
    cl.print(snagapanela);
    cl.print(" W / ");
    cl.print((snagapanela/560)*100);
    cl.println("%\",");

    cl.print("\"Teret\":\" "); // load at inverter side
    cl.print(snagainvertera);
    cl.print(" W / ");
    cl.print((snagainvertera/1200)*100); // load percentage
    cl.println(" %\"");

    cl.println("}"); //end of json data
}

And json data received by MM:

{
"Info":" ON",
"Baterija":" 26.15 V",
"Struja":" -0.79 A",
"Proizvodnja":" 6.72 W / 1.20%",
"Teret":" 27.52 W / 2.29 %"
}

And result:

Back of the cabinet (I have to tie those cables):

It seems I’m having isues with Python.

I have reinstaled Python and Python3, npm, python-shell and node js. Nothing worked. It was sending errors even with blank arduino, arduino sending only “starting” and “started” commands…
So, due to my lack of knowlege of Python or anything else surrounding ArduPort, I’m abandoning it…

To bad. It is very elagant module.

How do I do that?

I have reinstaled all original files for arduport and started debuging… Again.

I didn’t mention it before, but I’m running MM on Raspbian lite.
I’ve found I had problems with python. Force reinstalling modules solved it.

I have allso found some errors in arduino.py,
Had to change:

rgxData = re.compile("[[][a-zA-Z0-9-].*[\:][a-zA-Z0-9-].*[\:][a-zA-Z0-9-.].*[\]]")

to

rgxData = re.compile("[[][a-zA-Z0-9\-].*[\:][a-zA-Z0-9\-].*[\:][a-zA-Z0-9\-\.].*[\]]")

and

incoming = self.arduino.readline(self.arduino.in_waiting).decode('ascii').replace('\r', '').replace('\n', '')

to

incoming = self.arduino.readline(self.arduino.in_waiting).decode('ascii', errors="ignore").replace('\r', '').replace('\n', '')

Now, when running

python arduport.py

I get this:

{"debug": "SerialPort shell started..."}
{"debug": "Waiting Ardunio to connect on port..."}
{"status": {"data": "connected", "name": "connect"}}
{"status": {"data": "starting", "name": "setup"}}
{"status": {"data": "started", "name": "setup"}}
{"sensor": {"data": "0.02", "name": "Baterija"}}
{"sensor": {"data": "-0.00", "name": "Struja"}}
{"sensor": {"data": "0.00", "name": "Solarno"}}
{"sensor": {"data": "-0.12", "name": "Panel"}}
{"sensor": {"data": "-0.00", "name": "Inverter"}}
{"sensor": {"data": "0.04", "name": "Baterija"}}
{"sensor": {"data": "-0.00", "name": "Struja"}}
{"sensor": {"data": "0.00", "name": "Solarno"}}

I’m guesing, this should be working now. But ArduPort is still stuck at “Waiting for connection…”

EDIT:

Here is C/P from chrome console:

Starting module: MMM-ArduPort
MMM-ArduPort.js:286 [MMM-ArduPort]:: MMM-ArduPort: status
MMM-ArduPort.js:286 [MMM-ArduPort]:: MMM-ArduPort: {

MMM-ArduPort.js:286 [MMM-ArduPort]:: MMM-ArduPort: "pyshell-throw"
MMM-ArduPort.js:123 [socketNotificationReceived::error]:

I’m having trouble setting up MMM-ArduPort. So if anyone can help…

I have to point out that I’m using SAME serial port on arduino for communication with raspberry and RS485 network. For transmiting and receiveing data on RS485 I use fantastic EasyTransfer arduino library.

Posible problem:
When arduino receives data from RS485, it gets to TX pin on USB side and never gets to raspberry. Wich is good.
When arduino is sending data, to transmit over RS485, it first have to activate transmision mode on RS485 module.
In this situation, data is being sent from arduino TX to RS485 RX. But it is allso sent to USB RX, and to raspberry. Wich is bad. I gues.

Here are symptoms:
MM starts and ArduPort is waiting for arduino.
I connect arduino, ArduPort receives “[status:setup:starting]” and “[status:setup:started]”
ArduPort shows my sensors list and then it removes them and returns to “Waiting for connection…”

My arduino code sends “[status:setup:starting]”, waits for 3 seconds and sends “[status:setup:started]” witch is normaly received by Arduport.
But! Arduino then sends request for sensors status to RS485 wich is allso transmited to raspberry. I think that in this moment it switches to “Waiting for connection”.

But, again, I have modified MMM-ArduPort.js so it doesen’t disconnect (commented ), and I have aded “this.isArduinoStarting = false;” and “this.isArduinoStarted = true;” right after "case ‘sensor’: "
I modified this so arduino always stays connected, and data should be displayed whenever and whatever sensor data is received. And it actualy does switch to listing my sensors, but, again, sensor data isn’t shown.

I taught that EasyTransfer requests that get to PI are chrashing communication, but after my mod, I can see that data is passed normaly and is not affected by EasyTransfer part.
I gues, that part is discarded at this part in arduino.py

match = re.match(rgxData, data)
if match:
            data = data[1:-1]
            case, name, value = data.split(":")
            to_node(case.lower(), {"name": name, "data": value})

Here is photo of data being received on screen /dev/ttyUSB0 (yes… photo. I was in a hurry…)

Pictograms between [sensor:name:data] are EasyTransfer requests.

I’ve even tryed this modification. It didn’t help.

I’m having trouble uploading pictures…

But, I’m allso having trouble with MMM-ArduPort. It connects to arduino, shows sensors, and then returns to “waiting for connection…”

It’s been a while…

So, I mounted my MM in place, customized it to my preference and enjoyed it for a while.

If you read my other post about sending data from arduino to MM over ethernet, I’ve given up from it as I realy suck at programming web aplications.

But, it’s not all lost. I’m running my “not so smart” home on multidrop RS485 network and my master node is right behind RPI3 running MM.

So I made packet sniffing node using arduino nano.
In short, it listens for packets that are interesting to be shown on MM, translates them to format for MMM-ArduPort and sends them over usb. If no packet is received in 5 minutes, than it sends request.

So I installed MMM-ArduPort, configured config.js and then…
Disaster! I was only getting black screen! I taught: “NOOOOO!!! I’m to ugly to watch my self in a mirror!”
Started to remove modules one by one and nothing helped.
So I deleted MagicMirror folder and went to reinstal. But instalation got frozen at “Updating packages”.
Fortunatly, manual instalation worked. I reinstalled all modules and copied configuration from old config.js (yes, i made backup ), and finaly got it to work.

Problem was that i have updated it prior installing MMM-ArduPort and somehow update crashed MM.

Now it is 1:57 am so I’m going to sleep. Arduport will have to wait till morning.

I’ll slap some new pictures tomorrow!

So, here is my build…

Electrical cabinet:

And my test setup:

For now, I’m runnung it on VirtualBox running Raspbian like distro.

I’ll add MagicMirror to that PI once I learn to fine tune MagicMirror and when my kids let me.

I never expected it to look so good!

@sdetweil
Thank you!
Ill need some time to try it out.

Mechanical or should I say, woodwork is finished. I’m still waiting for short hdmi cable, PIR sensor and hinges I ordered… It looks sexy alredy! Can’t wait to see it working.
