Migrating from Legacy Blynk! Any recommendations?

I am looking for an alternative to the Blynk platform. The legacy is great but the new one is strongly pusing away the makers with the stupid high prices. I am just a maker, I am not doing any business. I use ESP32 and ESP8266 for my projects.

The features I am looking for are:

- Local Server only

- Monitor if the IoT device is Offline/Online

- Do basic Input/Output

- Charts

- Realtime Notifications

- I use hardware RTC, but it would be handy to be able to get it from the server

- Be able to send commands from an IoT device to another

​

Any recommendations are much appreciated!
