      @r_255 I don't know about this mqtt implementation, but in general, one would use _brightness.toInt() or _brightness.toFloat() to turn variable _brightness from a String into a number. Hope that helps.

                      String b = ez.buttons.poll();
                      
                      if (b == "right" && brightness <= 90) brightness += 10;
                      if (!brightness) brightness = 100;
                      if (b == "left" && brightness > 11) brightness -= 10;
                      if (b == "left" && brightness < 11) brightness = 0.01;
                      bl.value((float)(brightness));
                      if (b == "ok") break;
                      if (b == "off")brightness = 0.01;
                      if (b == "on")brightness = 100;
                      if (b == "up") loop();
        }
         
        // Prepare a JSON payload string
          String payload = "";
          payload += "{";
          payload += "\"command\": \"switchlight\", \"idx\": 143, \"switchcmd\": \"Set Level\", \"level\":";
          payload += brightness;
          payload += "}";
        
          // Send payload
          char attributes[100];
          payload.toCharArray( attributes, 100 );
          client.publish( "domoticz/in", attributes );
          Serial.println( attributes );
          menu_brightness_slider();
        }
        

        This works ! :O)

              Strang bug appears in this code

              #include <M5ez.h>
              #include <ezTime.h>
              #include "images.h"
              #define MAIN_DECLARED
              void setup() {
              #include <themes/default.h>
              #include <themes/dark.h>
              ezt::setDebug(INFO);
              ez.begin();
              }
              void loop() {
              ezMenu images;
              images.imgBackground(TFT_BLACK);
              images.imgFromTop(40);
              images.imgCaptionColor(TFT_WHITE);
              images.addItem(sysinfo_jpg, "Photo Turntable", sysInfo);
              images.run();
              }

              The title "Photo Turntable" get printed on the top and the bottom of the screen.
              (sorry no picture)

                @ajb2k3 You're absolutely right: the feature to be able to change the captions of text menus while the menu is active had introduced this error on some image menu displays. Fixed in version 2.0.1 which I just released. :)

                  I was messing with the image menu trying to create an image screen.

                    @ajb2k3 Single image screens can be done with a one item menu. I was thinking of also adding the possibility of providing an image to ez.msgBox, but probably the 1-item menu approach is more flexible because it allows for a caption.

                      You could also add just an image to your mez screen.like this. But it has to be on a sd card.

                      M5.Lcd.drawJpgFile(SD, "/c50x50_light_icon_off.jpg",20, 75, 50, 50);

                      Below is my experiment to make my own dynamic slider to get familiar with the arduino ide and m5ez
                      The end goal is to read the value from mqtt and set the slider to the known value of the dimmer and set it

                      int bar_position = 25 ; // START POSTITION ( TO DO : READ THIS VALUE FROM MQTT AND SET IT )
                      

                      Drop the line above in top of the m5ez to set the start position of the bar. Paste the below code in de the m5ez demo add to the main menu.

                      void menu_brightness_slider(){
                      
                        int Bar_step_amount = 10;  // bar is devided in XX steps ( for on/of set to 1 )
                        int Bar_lenght = 275; // Length of the slider bar
                        int Bar_height = 28;  // Height of the slider bar
                        int Bar_steps = Bar_lenght / Bar_step_amount;
                                
                                    
                        int Top_hLine_Start_X = 22; // X postion on screen from the left side
                        int Top_hLine_Start_Y = 150; // Y-postition on screen from the top
                        int Top_hLine_End_X = Bar_lenght + Top_hLine_Start_X ; // X End line postion on screen from the left side
                        int Top_hLine_End_Y = Top_hLine_Start_Y;
                      
                        int Bot_hLine_Start_X = Top_hLine_Start_X;
                        int Bot_hLine_Start_Y = Top_hLine_Start_Y + Bar_height ;
                        int Bot_hLine_End_X = Top_hLine_Start_X + Bar_lenght ; 
                        int Bot_hLine_End_Y = Bar_height + Top_hLine_End_Y ;
                                    
                        int Start_Point = Top_hLine_Start_X;
                        int End_Point = Top_hLine_Start_X + Bar_lenght;
                        int But_Radius = 10; // size of the slider indicator 
                      
                        int mid_button = Top_hLine_Start_Y + ( Bar_height/2 );
                        int bar_start_position = Top_hLine_Start_X + ( But_Radius ) ;
                        int bar_end_position = Top_hLine_End_X - ( But_Radius ) ;

                        payload += dimmer_value;
                        payload += "}";
                      
                      
                        // Send payload
                        char attributes[100];
                        payload.toCharArray( attributes, 100 );
                        client.publish( "domoticz/in", attributes );
                        Serial.println( attributes );
                        menu_brightness_slider();// Loop and restart slider
                      }
                      
                      

                      Not as dynamic as i wished, but its a start and with some parameter adjustments the slider bar can be converted to any size and even one that looks like a on and off switch, with only 2 positions.
                      Why not just draw a rectangle instead of 4 lines ? Well the lines could be replaced by bitmaps, so the slider button will run between bitmaps instead of over ( stacked bitmaps give me a kind of interlaced images and looks odd )

                      in this example i convert the slider bar to a scale of 0 - 100 and post in to my domoticz setup thru mqtt ( json formated )
                      The mqtt part of the code is missing, but thats nothing more than adding the library in the arduino ide and set the parameters.
                      Next step will be separate the mqtt part and run that on a different core, so connection won't stall over time.

                        Having fun with m5ez

                        0_1540462728485_IMG_0144.jpg

                        Now i am a copy and paste my own code .... coder....
                        Copied my slider and made a mechanism that selects and sets each slider.
                        Next and previous makes you jump between each slider, left and right sets the value , ok publishes the value and up gets you back to the main menu.

                        I still have issues to get my values in to m5ez object like the header, text works fine but int is still a issue. Tried to convert them to chars, but failed....
                        So much to learn at once.
