Hello everyone,
a few friends and I want to build a mobile party trolley and control the lighting with WLED. Unfortunately, we are still total beginners.
We would like to use a Raspberry Pi to connect a touch display to it in order to control the LED strips via WLED. Is this possible at all, and is it possible to control WLED without internet connection?
Best regards
Hi,
The standard WLED UI is web-based. So any device with a web browser (smart phone, tablet, laptop/PC, etc) should be able to display the WLED UI. This also means that using a touch screen on the device should just work – that’s exactly how you control WLED using your smartphone 
A fresh WLED installation will advertise its own soft Access Point (AP) SSID upon boot. This means that you do not require an Internet connection to use WLED, just WiFi access (or Ethernet if the controller supports it).
So, power up the controller running WLED, then search for available networks on the Pi:
- SSID: WLED-AP
- Passphrase: wled1234
Once the Pi is connected to the WLED WLAN, type IP address “4.3.2.1” on the web browser and the WLED UI should get displayed. Check the official getting started wiki out for more.
Hope this helps!
