You need to add the file to the project via Sketch > Add file - The file should be where you downloaded the project

[@tiberiud1955]

Does this code work with the bigger display ?T display S3?

[@gianlucapasciuto8007]

has anyone fixed the API problem? to me it makes the connection, you see a blank graph and then comes back to the connection again. Has anyone solved it?

[@stevejacobson7431]

Cool! Can't wait to gather the parts and build this one!

Hello, I tried to use this but I can’t get passed the “Connected” screen. It says connected, and then displays an empty graph for 2 seconds, and goes back to “Connecting” screen, and the same thing happens over and over until I cut power. Any ideas?

Hi! I'm not sure why but it's on a loop for me, shows connecting..... connected!! then shows an empty graph and an empty green square for the "updated:" field, then the screen blinks off for a half a second back on then continues the loop starting from connecting. In the serial monitor I get: rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:2 load:0x3fff0018,len:4 load:0x3fff001c,len:1044 load:0x40078000,len:10124 load:0x40080400,len:5828 entry 0x400806a8 ets Jul 29 2019 12:21:46 over any over with nothing changing one time I did see the btc logo for one loop but not anymore. This project looks awesome and any help would be greatly appreciated!

Did you change wifi data in code, Ssid and password. Also new modems can mak problems, try to connect to some other wifi network

@@indevor8337 No I didn't, or its better say, I did but on a half. the problem in that when I open website or the sketch open website with json file. first I see page: ddos protection "Cloudflare", and after a couple seconds appeared json page with data. and the reason sketch is not ready to see cloudflare and its crashes.

[@zodchiy3d]

Hi! Thanks for the project. Can you please tell me if the ticker takes the data from the Internet via WiFi? I want to make a souvenir for my relative, so it works independently from the battery and takes data via WiFi.

Hello, How can I manually put the mac address for TTGO T-Display? I need it because my home wifi won't allow devices to connect unless I add mac address for the device.

[@VolosProjects]

You dont need to add Mac to ttgo, each esp32 device have its own mac adrees, you will need mac scaner for esp33, just google it an you will find sketch

[@gianlucapasciuto8007]

Hi, sorry I don't speak English well, but to program the TTGO you need to have ArduinoUno or can you connect the TTGO directly to your computer and you can directly send the code to it? Thanks

[@VolosProjects]

You can connect directly. TTGO is development board like Arduino Uno , but ttgo is faster and have built in display

Great project! I tried to do it with a LILYGO TTGO T-Display but the screen prints only some objects, like the grid and the textbox, and after that it goes black again until the next iteration. Do you know what could it be? maybe the ESP board manager version or the board selected? Thanks!

Solved. The API is no longer available. Changed it and it worked.
