Hi

I'm using espnow.
My architetture is Many to One
How many transmitted device I can associate to one receiver?

Thanks

Hey! I’ve worked with ESP-NOW in a few projects, and you can typically link up to 20 devices to one receiver. Just a heads up, though: as you add more devices, you might run into some interference or data traffic issues, so keeping an eye on how everything performs is a good idea.
