You don't need to connect dozens of devices. Esp32 can communicate as a server or a client so you can directly connect them without getting the router involved.

Say, your house has 15 light switches on esp32 running Tasmota. Do they all talk to each other in a mesh network, or do they all connect to your router in WIFI infrastructure mode?

  There's a protocol called ESP MESH, with which multiple ESP32 (and ESP8266) can talk to each other. > ESP-WIFI-MESH is a wireless communication network with nodes organized in a mesh topology using the simultaneous AP-STA feature on Espressif SoCs. It provides a self-forming and self-healing network, with ease of deployment. The network topology of ESP-WIFI-MESH can scale up to 1000 nodes in large areas. https://www.espressif.com/en/products/sdks/esp-wifi-mesh/overview https://www.espressif.com/en/products/sdks/esp-wifi-mesh/ove... https://randomnerdtutorials.com/esp-mesh-esp32-esp8266-painlessmesh/ https://randomnerdtutorials.com/esp-mesh-esp32-esp8266-painl... --- I didn't know that home WiFi routers have difficulty with more than a dozen connections, but I imagine ESP MESH could be a way around it, where a few devices connect to your router and act as access points for the rest of them.

  In addition to ESP-Mesh protocol as mentioned in the sibling's comment, alternatively ESP-Now protocol also enabled lightweight support for direct networking without AP: https://www.espressif.com/en/products/software/esp-now/overview https://www.espressif.com/en/products/software/esp-now/overv... https://github.com/espressif/esp-now https://github.com/espressif/esp-now

  There are some mesh protocols (ESP-Link i believe) but tasmota doesnt support them. It doesn't even support SoftAP for anything but initial configuration. However there are some wifi repeater projects for the ESP series that might be of use.
