In the input field "OctoPrint Address (do not include http://)" I can't seem to add domains or subdomains instead of IP. This makes me unable to use different monitors for different instances. I also can't choose which printer to monitor, since it defaults to one of them only.

Please update with this functionality.

Hi there,

Would it be possible to show the weather when the print is complete instead of only when it's off-line? I leave octoprint on-line even when I'm not printing so with the current config the weather would never show. It would be awesome if - after the print is finished - it switched to the weather display.

When Printer-monitor detects Octoprint is operational, it changes from "clock" to the 3 sliding displays. If you do not do a print job, but power down Octoprint, printer monitor changes back to the "clock" mode.

However, if any print job has been started or ended and then Octoprint is shutdown, Printer Monitor remains in the operational state (sliding displays of the last print job).

In OctoprintClient.ccp, two lines added in the OctoPrintClient::getSubmitRequest will correct it.

The line is:
printerData.isPrinting = false;// so we aren't printing if the connection failed
Add it after nulling out the printerData.state="" lines

WiFiClient OctoPrintClient::getSubmitRequest(String apiGetData) {
  WiFiClient printClient;
  printClient.setTimeout(5000);

 Serial.println("Getting Octoprint Data");
  Serial.println(apiGetData);
  result = "";
  if (printClient.connect(myServer, myPort)) {  //starts client connection, checks for connection
    printClient.println(apiGetData);
    printClient.println("Host: " + String(myServer) + ":" + String(myPort));
    printClient.println("X-Api-Key: " + myApiKey);
    printClient.println("User-Agent: ArduinoWiFi/1.1");
    printClient.println("Connection: close");
    if (printClient.println() == 0) {
      Serial.println("Connection to " + String(myServer) + ":" + String(myPort) + " failed.");
      Serial.println();
      printerData.error = "Connection to " + String(myServer) + ":" + String(myPort) + " failed.";
      printerData.state = "";
      printerData.isPrinting = false;// if the connection failed, switch back to clock (not printing)
      return printClient;
    }
  } 
  else {
    Serial.println("Connection to OctoPrint failed: " + String(myServer) + ":" + String(myPort)); //error message if no client connect
    Serial.println();
    printerData.error = "Connection to OctoPrint failed: " + String(myServer) + ":" + String(myPort);
    printerData.state = "";
    printerData.isPrinting = false;// if the connection failed, switch back to clock (not printing)
    return printClient;
  }

I can't seem to get the configuration right. I keep getting the forbidden error. There are a couple new fields in the config that was not in the video I was watching. The video was 1.2 and this is 1.7. The API key and IP address are correct. How critical is the host name, OctoPrint User/Password? I have tried my main username/password without success and even added another account, but with no luck.

I get this error message:

The configuration page of the web interface correctly saves the www_password when the save button is pressed, but when the page loads the next time, the field is cleared again (which I think is also the right choice). The trouble is that if you hit save again, to save another setting, the password gets cleared. And then you're locked out, unless you enter a blank password in the authentication dialog.

I was thinking that you could either:
a) check for an empty password, and choose not to set www_password if it's empty, but someone might want an empty password, IDK.
b) set the field to something weird, like notapassword and then if the form comes back as notapassword, then you don't set www_password. Then you wouldn't be able to have "notapassword" as your password, but maybe it's OK to make someone mad?

I noticed that in the home page (web interface) there is the english term and local term between () for weather condition, although on the display, no matter what language you set in the settings file, you always have the english term for weather condition.
Is it correct? Some weather condition in italian are very long words and maybe you evaluated not feasible to put it in the display...

I was wondering if any plans to enable this to monitor prints directly from a printer running RepRap Firmware (I.e. on a Duet) without having to have a Pi running Octoprint acting as a middle man?

Thanks!

Hey Ho Guys,

I just got all parts out of my Letterbox, threw everything together and was about to program my wemo but I can'nt figure out whats the Problem with this error status U_u
At least there is no issue about this yet

Why it shows AM/PM even in 24h mode? It is possible to show something else instead? I don't know current time or weather temperature. It's odd seeing 15:30 PM, very appreciated, thanks

Using current master branch revision results in a crash loop after wifi settings have been configured if ENABLE_OTA is set to false in Settings.h. No other settings have been changed. Everything works as expected during manual wifi configuring but once the configuration has been given then a crash loop follows and the web interface can't be accessed for further configuration. This appears to happen only if ENABLE_OTA = false. With the default "true" value everything works as expected.

Tested with Arduino 1.8.7, WiFiManager 0.14.0, esp8266 2.4.2, so essentially the latest ones. Not sure if this issue is library or implementation related.

When the Printing Time and/or Time remaining is over 24 hours it only shows the remainder of hours above any 24/48/72 hour full days. On a long print currently running I have Print time of 54:37:15 shown on octoprint web interface with 6:37:45 on the print monitor. The remaining time is now under 24 hours, but a similar effect was happening with the Remaining Time when it was 25:15:10 on the web/telegram plugin it showed 1:15:10 on the printer monitor.

How can the code be updated to accommodate times greater than 24 hours?

I tried to use my duckdns address to connect to my octoprit so I can use my monitor at work. When I enter the duckdns address and save it, the config page reverts back to the internal ip of octoprit.

Is it possible to use a web URL to connect?

Adding a battery shield for full Wireless use is without a doubt possible. But I'm wondering if you could read the battery level through one of the analog pins every so often and display it on the display?

Hi,

I'm getting this issue -

sketch/OpenWeatherMapClient.cpp: In member function 'void OpenWeatherMapClient::updateWeather()':
OpenWeatherMapClient.cpp:78:3: error: 'DynamicJsonBuffer' was not declared in this scope
   DynamicJsonBuffer jsonBuffer(bufferSize);

Apparently it's been seen before but was "fixed" Anyone know how did you fix it please?

Please add the functionality for setting our own NTP server + country/city for the time. This would resolve having to set UTC offsets manually, especially with daylights savings

hey, have some problems while compiling.
do your have a solution?

thank you!

Hello
I compiled code v2.3 and put it into a wemos d1 mini with SSH1106 display (I use D3 & D4) and it is all ok till display the message to use the web server with ip address and port... From the serial I see the sketch running, downloading time and weather forecast, all seems ok. On the display I don't get any update after the first message, logo, and ip and port address!

Please note that on the same hardware with the same arduino IDE and same libraries I run the weather station demo from thingpulse (same libraries used as you) and all is ok... Can't figure out what is going wrong...

Hi. How do you update the firmware through the interface? Do I need to compile my own .bin file?

Probably just my preference but on my LCD printer displays that I've been staring at for the last 3,700 hours (2004 LCD's Marlin) they always read tool temp/bed temp.

I added the orientation as an option:

Settings.h
boolean SHOW_TOOL_BED = true;// left right orientation of temp displays

printermonitor
void drawScreen1(OLEDDisplay display, OLEDDisplayUiState state, int16_t x, int16_t y) {
display->setTextAlignment(TEXT_ALIGN_CENTER);
display->setFont(ArialMT_Plain_16);
int bed = printerClient.getTempBedActual().toInt();
int tool = printerClient.getTempToolActual().toInt();
if (SHOW_TOOL_BED == true) {// shows tool temp/bed temp
display->drawString(64 + x, 0 + y, "Tool / Bed Temp");
display->setTextAlignment(TEXT_ALIGN_LEFT);
display->setFont(ArialMT_Plain_24);
display->drawString(2 + x, 14 + y, String(tool));
display->drawString(76 + x, 14 + y, String(bed));
display->setFont(ArialMT_Plain_16);
display->drawString(42 + x, 14 + y, "C");
display->drawString(104 + x, 14 + y, "C");
} else {
display->drawString(64 + x, 0 + y, "Bed / Tool Temp");
display->setTextAlignment(TEXT_ALIGN_LEFT);
display->setFont(ArialMT_Plain_24);
display->drawString(2 + x, 14 + y, String(bed));
display->drawString(64 + x, 14 + y, String(tool));
display->setFont(ArialMT_Plain_16);
display->drawString(38 + x, 14 + y, "C");
display->drawString(115 + x, 14 + y, "C");
}
}

When the available wifi network isn't available, the default 8266 name is ESP + chip ID, and if you have a shop full of 8266's kind of hard to remember all the chip ID's.

//or use this for auto generated name ESP + ChipID
wifiManager.autoConnect();

Suggest a change to use the user defined Hostname instead:

// wifiManager.autoConnect();// old line
if (!wifiManager.autoConnect(HOSTNAME)) {// new addition
delay(3000);
WiFi.disconnect(true);
ESP.reset();
delay(5000);
}
//

Hostname will then show up as the access point.

I have Problems at the moment my printer finished. After that, time remainig displays an old value. Is it possible to fix it or give a message, finished?

Right after uploading, my screen suddenly went static. The static isn't moving, but there's a black bar across the screen that jumps around every once in a while. If anyone knows what's up please help. Thanks!

Request to add basic auth support using haproxy. Currently if haproxy is in use with basic auth a HTTP/1.0 401 Unauthorized response is given.

Hello!
The screen just doesn't work tried different pins added pull-up resistors 5v or 3.3v
But if i use the adrafruit ssd1306 library it works.
Any tips?
TIA

I was having a few declaration errors, it seemed each time I would fix one another would pop up.

I found that the libraries used need to be at specific builds and not necessarily the newest build will work.
Arduino IDE
v1.8.10.0

Board Mangaer
esp8266 needs to be at v2.4.1

Library Manger
WifiManager needs to be at v0.12.0
ArduinoJson needs to be at v5.13.1
and the
SSD1306 needs to be at v4

Hope this helps

It would be great if in addition to Printing Time and Time Remaining the print monitor had an ETA screen with displaying (current time+time remaining).

something like this maybe? https://github.com/pablogventura/Octoprint-ETA/blob/master/octoprint_eta/__init__.py

When I compile latest master against latest libraries, I get:

Any ideas?

hey, is it possible to add a authentication for the OTA flashing?

thank you!

So as the tile says ...
when I try to configure the Wemos through the web page the Wemos simply reset.
I can't even change the source code because it doesn't change anything.
It can be the fault of my Wemos (maybe somewhere broken), I wait a new one but I'm wondering if someone has the same issue.

Thank for you project it's awesome btw !

For some reason my 1.3" OLED display from Waveshare did not work out of the box. I managed to make it work by resetting the display before initializing. I added this:

  pinMode(D3, OUTPUT);
  digitalWrite(D3, HIGH);
  delay(1);
  digitalWrite(D3, LOW);
  delay(10);
  digitalWrite(D3, HIGH);

before display.init(); in the setup function.
(D3 is connected to the OLED's reset pin)

Is there perhaps any change you will include the news headlines module from your "marquee-scroller" project into the printer-monitor?

This will make your printer-monitor even more awesome!
Thx for the project anyway

When Octoprint installs you always have to give it a name as it appears on the network, so I figured why not use it instead of a hard coded, sometimes prone to change, IP?

Let Printer Monitor do a scan at the startup, find the matching name that was used for the Octoprint install, then set the IP itself. Regardless of the router changes, printer monitor will always find Octoprint's IP.

Mel

Settings.h
String OctoPrintServer = "x.x.x.x"; // IP or Address of your OctoPrint Server (DO NOT include http://)
String OctoHostName = "DROOLER";// name of the octoprint install

printermonitor
void setup() {
findMDNS();// insert as very last line in setup(), go find Octoprint
}

void findMDNS() {
// We now query our network for 'web servers' service
// over tcp, and get the number of available devices
int n = MDNS.queryService("http", "tcp");
if (n == 0) {
Serial.println("no services found");
}
else {
for (int i = 0; i < n; ++i) {
// Going through every available service,
// we're searching for the one whose hostname
// matches what we want, and then get its IP
//Serial.println(MDNS.hostname(i));
//Serial.println(MDNS.IP(i));
//Serial.println(MDNS.port(i));
if (MDNS.hostname(i) == OctoHostName) {
OctoPrintServer = String(MDNS.IP(i));// shove in the IP of the octoprint instance
}
}
}
}

HI, would it be possible that PRINTER_MONITOR, check the same information form two different octorint instances.
IT would require duplication of the OctoPrintClient.h and allow version OctoPrintClient1 and OctoPrintClient2 in configuration.

This way we don't need one monitor per printer...

Thanks!

I would like to add the ability to see the current Z position during a print. I often need this when awaiting a color change or just to see how things are moving along.
I looked at the Octoprint API and it looks like this is only available with a push request from Octoprint, not as something I can query.
Can this be added or can someone advise me on how?

Thanks

If would be nice it it is possible to set the hostname of the device so that it gets registered in DNS correctly and not with a default unique (in my case esp_1d8650) name.

Can be through the UI or in the initial configuration when compiling the firmware.

It's possible to add Multilingual support for OpenWeatherMap
I have try and it works on French

add &lang=xx on apiGetData
and add xx on setting.h with this choice :
Arabic - ar, Bulgarian - bg, Catalan - ca, Czech - cz, German - de, Greek - el, English - en, Persian (Farsi) - fa, Finnish - fi, French - fr, Galician - gl, Croatian - hr, Hungarian - hu, Italian - it, Japanese - ja, Korean - kr, Latvian - la, Lithuanian - lt, Macedonian - mk, Dutch - nl, Polish - pl, Portuguese - pt, Romanian - ro, Russian - ru, Swedish - se, Slovak - sk, Slovenian - sl, Spanish - es, Turkish - tr, Ukrainian - ua, Vietnamese - vi, Chinese Simplified - zh_cn, Chinese Traditional - zh_tw.

Thanks for your work

I like using the hostname for OTA, otherwise in the Arduino IDE port menu it shows up as a ESP8266xxxx....

In the Setup(), I added the line:

ArduinoOTA.setHostname((const char *)hostname.c_str());// added line
ArduinoOTA(begin);// original line

In the Arduino port menu it now shows "Octomon at xxx.xxx.xxx.xxx" or whatever the hostname is set to. Handy in the event you have a workshop full of ESP8266's...:-)

Mel

Like the #46

I change the settings.h before the first upload to the Wemos.. BTW if i change by the web interface the port is stuck at value 80

Would be nice to have an (additional) configuration option to display weather when octoprint server is connected but no print job is running.

Hi, I have this fantastic project up and running, one question for this 1.3 display. The entire display is shifted down one pixel or line I guess is more accurate, the bottom row of the word 'offline' is missing.

Any way to edit some line in IDE to raise it up one line, am digging around but this is well above my head currently, am working on it.

Thank you very much

Showing while compiling the sketch ('DynamicJsonBuffer' was not declared in this scope) plz suggest

I'm using NodeMCU 1.0's, but I had to add an option to rotate the display into its normal orientation.

Settings.h
boolean INVERT_DISPLAY = true;// flip the display to normal orientation, pins at top when viewing the face

printermonitor
// initialize display
display.init();
if (INVERT_DISPLAY == true) display.flipScreenVertically();// connections at top of OLED display

// Initial UI takes care of initializing the display too.
ui.init();
if (INVERT_DISPLAY == true) display.flipScreenVertically();//connections at top of OLED display

When i trye to acess /configure from the menu, is says login and when i use the default admin/password it wait a littel and then ask for login again, and this dos i over and over again :-)

I just updated to v2.1 and I am not getting a connection failed on the web page and the display says the printer is offline. I am able to get to the printer on my PC's web browser. I have a second monitor that is v1.7 and when I change the IP address and API key, connects up fine (both printer uses the same user name/password). Watching the serial monitor, I don't get any addition information to explain what the issue is.
