 | [IO/Pin Roles](https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/ioRoles.md) (79 total) | You can set pin roles in 'Configure Module' section or use one of predefined templates in Web App. For each pin, you also set coresponding channel value. This is needed for modules with multiple relays. If you have 3 relays and 3 buttons, you need to use channel values like 1, 2, and 3. Just enter '1' in the text field, etc. |

 | [Channel Types](https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/channelTypes.md) (41 total) | 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 UI radiobutton on OpenBeken panel.<br>Some channels have '_div10' or '_div100' sufixes. This is for TuyaMCU. This is needed because TuyaMCU sends values as integers, so it sends, for example, 215 for 21.5C temperature, and we store it internally as 215 and only convert to float for display. |

From the firmware point of view, scripts and autoexecs are basically the same thing. There is, however, a little bit more advanced system of execution for scripts which can be written in a form of scripts threads that run over time, can have delays within then, conditional checks and jumps. |
