+Maiko Ito I have not tried fastled yet with the ESP but I have a basic Arduino sketch than allows to configure WLAN access via ESP access point and can give you the skeleton for service other web pages, e.g. for the config options you’re thinking about.
What a difference a year (and an Arduino IDE) makes - not to mention the sterling work Mark and Daniel have done to port FastLED to the ESP. Thanks a bunch, guys. Just getting back into it and it’s just so nice to be able to easily put together things like HTTP, MQTT and FastLED.
