Benefits of using esp-host
- extremely low cost hardware , available worldwide
- ability to run 24/7 via usb, self-hosted payloads, no external apps or programs required.
- includes stable payloads, no memory errors or reloading pages.
- completely block all updates
- no need for custom dns server or settings, features automatic redirect
- easy to program and update via usb
- very low power consumption
You can download the payloads from the developer’s github here.
On the same page, the developer gives details on how to flash the payload into the ESP8266, reproduced below:
Requirements:
-esptool.py https://github.com/espressif/esptool
-ESP8266 Module with at least 4M flash
-Firmware 4.55 or 4.05
-esphost.bin or esphostmulti.bin or esphostmulti405.bin
Payloads included in esphost.bin
-VORTEX HEN 1.4
Payloads included in esphostmulti.bin
– HEN (stable)
– HEN+VR (stable)
– FTP (stable)

Instructions:
Flash esp host using the following command:
sudo esptool.py –port /dev/ttyUSB0 write_flash 0x00000 ./esphostmulti.bin
-after flashing completes, connect to “PS4-WIFI” using “easy setting” then go to [Settings] > [User Guide]
-NOTE: windows users must use the appropriate com port when flashing with esptool.py
-NOTE2: users can optionally flash using the GUI version of esptool https://github.com/Rodmg/esptool-gui
