OpenWRT TTL manipulation on a travel router explained

Setting the TTL to 65 can help solve OpenWRT hotel captive portal issues on a travel router because of the way captive portals often track and manage connected devices.

Here’s an explanation of the key reasons:

Device Differentiation:
Captive portals typically recognize and manage devices based on their MAC addresses and IP addresses. When you connect a device (like a laptop or phone) directly to the hotel's network, the captive portal captures the MAC address of that device and redirects it to a login page.

# Controlling my Buva Qstream ventilation system using:
# * A Wemos D1 mini lite (an ESP8266 based board)
# * A Wemos power shield so I can power the Wemos from the ventilation units 12V supply.
# * A simple PWM to 10V convertor like this: https://www.cheaptech.nl/pwm-signaal-te-voltage-converter-1-3-khz-0-10-v-pw.html
# * The amazing ESPHome firmware tool: https://esphome.io
# * Home Assistant to tie it all together: https://www.home-assistant.io
#
# I used to use a Raspberry Pi and some Python code for this. See https://gist.github.com/SqyD/a927ab612df767a0cc892bcde23d025c
# The Wemos approach seems more stable and doesn't require external USB power.
