I’m planning to create some scoreboards for our tabletennisclub with ESP32’s
So far as stand-alone, it goes pretty well.
Now I want also a webpage to show the live scores of the matches.
I’m wondering what is the best way to follow.
- I need to detect the right scoreboard placed at a table
- I want to be able to send some data to the scoreboard (players, …)
- I want to show the current scores from each board.
- I plan to make multiple scoreboards but, depending of the day, I need only some of the boards(2,4, …)
I think of one ESP23 acting as webserver as ‘Master’ where all the scoreboards connect to (or send their data) with ESP-Now or ESP-Mesh. Do I think in the right direction?
Many thanks in advance,
Using ESP-NOW might be a good idea. You can also use MQTT.
See with which method you want to proceed.
We have several MQTT tutorials on the RNT blog:
We also have multiple tutorials about ESP-NOW. We have this project with a web server that might help:
I already tried the tutorials about ESP-NOW and they seems for me a good direction. I think I need a combination of the one you mentioned here and this one https://randomnerdtutorials.com/esp-now-two-way-communication-esp32/
I also thought about MQTT but most need a Raspberry Pi and RedNode and I am a little ‘afraid’ to go that way. I am still new with Arduino and ESP32 but it seems easier than the PI way so I hesitate. I’m would love a MQTT tutorial that uses an online (free) broker, as a starting point to test that out.
But I am glad you confirmed my idea of ESP-NOW so I can experiment further in that direction.
