# API 6

API 6 is our current universal firmware that controls the *SimplePack, SimplePack Plus*, *SimpleLeak,* and *SimpleIndustry* devices. The API is programmed in a way that makes it easy to use for integrators who do **not** want to spend too much time configuring the devices and at the same time offers an endless amount of possibilities and behavior **customization** so even the most complex use cases can be covered.

If you’d like to become an [*expert* ](broken://pages/iJeeyDrOxkXwvWOvrnsb)integrator, expect a little learning curve.
