 ## ESP-NOW based remote control
-Since version WLED 14.0-beta3: An ESP-NOW compatible remote control is supported. An example of this is the „WIZmote“ remote control. This is based on an ESP microcontroller. ESP-NOW can be activated in WLED settings. You have to enter the Hardware MAC address of the remote control. This is determined by clicking on any button on the remote control and copying the last received MAC address from the "Last Seen" field to the "Hardware MAC" field in WLED ESP-NOW settings (“Config->WiFi Setup”) and saving it with "Save". Advantages: no special receiver needs to be attached to the WLED controller and the signals are transmitted via radio network. Therefore there is no line of sight between the remote control and the WLED controller required, as is the case with an IR remote control.

 The 4 buttons "1"-"4" of the WIZmote remote control are linked to presets 1 to 4. The meaning of other keys is self-explanatory. Attention: WIZmote needs two good quality AAA batteries to work properly. If the batteries are too weak, the correct signal will not be sent, even if the blue LED on the remote control lights up briefly, actually indicating signal transmission.
