I’ve got a developer account, but it’s not enrolled.. so just enrolll it pay 99$/y & everything will stay for a year? or can i do it without the enrollment also?

Thanks for your answer! indeed i have considered working with BLE, but i want to be able to control the led’s &…. From a distance. With the webserver i’be got now i can turn on/off light when i’m at work.. but it’s with around 15sec delay..
