Where can you purchase the module?
We do not sell any modules. We have only developed a suitable app to conveniently use this module for operating a garage door with a mobile device.
You can purchase a suitable module worldwide from many retailers and suppliers. Since the module does not have an exact name, it is not easy to provide a specific search term for it.
What is important is that the product description on the sales page states that the module works with the app 'TwoSwitchBle' or 'bleKEY'. Only then will it also work with our app.
Here is a collection of links that may help you find a suitable module.
