First of all: none of your work will be lost or locked. You’ll be able to continue.
However, in order for us to develop Blynk, we need to add paid paid services.
If you really like Blynk and think it saves your time, we hope for your support. Imagine byuing us a cup of coffee once a month - that would be the price.
I have looked all over the community and see bits and pieces related to subscription services. Is there a list in one central place that explains what the plan is and what things will require a subscription. I am sure you do not have all the answers yet. Maybe you could provide a basic idea of what the intentions are so that those who are developing projects using Blynk will have some idea of what those costs might be. For instance, I have read a few posts stating it will cost roughly the same as a cup of coffee per month. Does that mean just to have the app or what exactly?
