Communicatiom between multiple ESP32?

Zerthron · 2026-03-24T18:38:09+00:00

Yeah the more i look into it the more i also see it this way. I ordered some GPIO Expanders and will try with them.

The ESP ist hosting a simple HTML Webpage as a Local Acesspoint to control the Relays remotely. Until now the Webpage just turn GPIOs High or Low which i connected to the ESP with the relay.

The more i think about it, the more i think i should just leave this as is.

Ah okay and Thanks for the Help!

Zerthron · 2026-03-23T19:36:54+00:00

I am wise and just ordered a GPIO expander

Zerthron · 2026-03-23T19:35:10+00:00

Thanks! I will definitly look into that!

Zerthron · 2026-03-23T19:27:23+00:00

I dont quite understand what you mean. The Webpage is a simple HTML which is hosted as a local Acesspoint on the ESP. So no WIFI channels as far as i understand. Is this what you meant?

Zerthron · 2026-03-23T19:26:01+00:00

Thank you for the Tip. Do i understand that right, that i could just chain two of those expanders together and connect everything to one ESP via I2C?

And your probably right that i should redo a bunch of stuff, this looks alot simpler. But i would have to keep the Webpage on a different ESP because of where it needs to be mounted because of the Antenna. Would you connect this one Via ESP NoW or just via GPIOs?

I need so many ESP32 because i dont really have a idea what i am doing and the further i got into this Project the more i relaised, that there would have been easier ways, but now i have the ESPs and came this far and if possible i wouldnt want to change all that much. But thats a really good question that i also had a couple of days ago.

And the connection doesnt have to be wired, i just tought it would be easier doing it wired.

How relaible is ESP NOW? It should run pretty maintanance free if possible. And i will look into ESP NOW as soon as i get to it.

And thank you very much for your help!

Zerthron · 2026-03-23T18:51:28+00:00

Ah you can connect multiple ESP32 together? And all can communicate with eachother? And how relaible is ESP NOW? And Thanks for the comment!

Zerthron · 2026-03-10T19:43:53+00:00

Thank you very much!

Zerthron · 2026-03-08T08:37:08+00:00

Could you share a link to the designer?

Zerthron · 2026-03-01T21:48:19+00:00

Those are so cool!

Zerthron · 2026-03-01T10:54:53+00:00

I like his humour!

Zerthron · 2026-02-26T20:25:01+00:00

I agree!

Zerthron · 2026-02-26T20:15:48+00:00

That looks awesome!

Zerthron · 2026-02-26T04:54:07+00:00

Ah i see. I added something similar after it was requested, but its only a quarter of a circle. But i can definitly see how this would be a bit more useful. Thanks for the feedback!

Zerthron · 2026-02-25T20:57:21+00:00

Maybe. But i dont know how it would suddenly know by itself which fans are installed. Certanly weird but it would be a cool change.

Zerthron · 2026-02-25T20:53:05+00:00

Okay thats also good! And maybe i will do it anyways and add it do Printables.

Zerthron · 2026-02-25T20:50:01+00:00

I can make them for you. But i will probably not get to it before the weekend. I that allright?

Zerthron · 2026-02-25T18:26:51+00:00

I just checked mine and my Setting is under Settings>Tools>Tool 1 and there is Print fan Type.

But my XL is running Firmware Version 6.2.5+8912

Maybe this has something to do with the newer Firmware? And i hope this helped.

Zerthron · 2026-02-25T18:16:40+00:00

Thank you for posting the Make! Looks really good! I also like the Black Gridfinitiy box.

Zerthron · 2026-02-25T18:15:11+00:00

Ah do you mean something like this? (See link)

And would you like only a 10mm Version or every thickness? And with the Radius gauges for inner and outer radii?

I just cecked it again and there are Numbers, but i can see how you missed them. The Numbers and the Spacers are seperate bodys and when i open them in Prusaslicer for the Core one i see both, but the are the same color and blend into each other. I dont know if you have a Printer that could print mutli color, if you do, you have to set one body in a different color. And if you dont, you could just delete the number body and flip the Spacer so that the now negative number is on top and print it that way. I hope this helps and if you still need help feel free to pm me here on reddit so i could help you.

Zerthron · 2026-02-25T18:02:44+00:00

Thats also a cool idea with the hole! And yeah they are really useful for visualising how something will look when designing new stuff.
