I’m trying to decide which mesh network to use between painlessMesh or Lora (with Meshtastic). Wanting to network anywhere between 1 to 100 Esp32’s with GPS, IMU, pressure, temp and power sensors on each (every 10 secs) with distance being 50-1000 feet between devices. Also wanting to send txt messages between devices (connected to Android tablet) and have ability to control lighting. Meshtastic seems already built for this but don’t need to be transmitting that far and wanting simpler design and to keep cost per device down. Plus Lora is limited to world regions.
Each project and conditions are different. The best network for you will depend on many conditions.
You really have to try it out and see which one works best. First, on a small scale, and then, try to upgrade to the total number of ESPs.
I don’t think I can help much here, both seem good alternatives if used in the proper way.
There’s also the possibility of using ESP-NOW: https://randomnerdtutorials.com/esp-now-esp32-arduino-ide/
