When I had the previous version of Blynk I spent a few dollars on energy which is now worthless. I think at least they could make the amounts spent on energy available in subscription discounts. Even so, I won't pay as it's a non-commercial learning project. The widgets available on the free plan are VERY limited. It doesn't make sense to me. I'm going to look for another more complete platform that serves me free of charge for small projects.

Pretty disappointed. Legacy Blynk was great - had a ton of widgets, and was intuitive to use. Now even with payment, they lack many widgets from the old version. I used and paid for old Blynk for its ease of use & feature set, but now I'm better off putting in the time to develop full custom solutions since they've removed everything that made it good & easy to use.

Hi, the only widgets not available are the Timer and sensor widgets. Mail and notification widgets are not required now and can be configured to be sent automatically on hardware events or via automations. Automations feature is also a huge improvement over the old Eventor widget. We are working to make the new blynk more intuitive

I liked the legacy version where almost everything was simple and clear and you can do ALOT for FREE. I mean I get it, going enterprise is something everybody wants to do, but now with this newer version, not only it is complicated, you can do only few things with the free tier, alot of things are only limited to the PRO version subscribers. Subscription prices are waay high for a hobbyist. Will still use it though, but not with a big smile on.
