The ESP32 based mesh hardware have wifi built in. While they are not energy efficient enough for daily battery use, they do make good home nodes. As an example, tonight I flashed one of my Heltech V3 units to become a "weather bug". It is transmitting weather alerts for all counties in the North eastern corner of South Carolina. It simply plugs into a USB power port and connects to teh NWS via wifi and relays messages to the South Carolina region for Florence.

meshwxpro is the name of the firmware. It can be programmed to send alerts over meshcore or meshtastic.
