 # Channel Types
 
 Channel types are often not required and don't have to be configured, but in some cases they are required for better device control from OpenBeken web panel. Channel types describes the kind of value stored in channel, for example, if you have a Tuya Fan Controller with 3 speeds control,  you can set the channel type to LowMidHigh and it will display the correct setting on OpenBeken panel.
