Not true. Here a few examples:

- You can start flows with a variable text, number or boolean.
- There’s a very useful app [Advanced Triggers](https://community.homey.app/t/how-to-handle-multiple-triggers-resulting-in-one-action-in-advanced-flow/89283/3) that lets you pass multiple local variables.
- BLL formula as tag: [here](https://community.homey.app/t/developing-flows-tips-and-best-practices/117362/20)

Related: You can also store variables in an Advanced Device
