Hi @Dmitriy, I’m wondering if you could please confirm that the following Blynk legacy feature (send values as an array) is currently working in Blynk 2.0?
Blynk.virtualWrite(pin, "hello", 123, 12.34); // Send multiple values as an array
The reason why I ask is because i’m in the middle of transitioning existing projects to Blynk 2.0 and it appears the array values aren’t stored atm. 
Kind Regards, GG.
According to the documentation, it’s possible.
How did you configure your datastream ?
Take a screenshot please.
Hi @John93, Thank you for replying…here is my screen shot for one of the data streams i’m wanting to store array data,
Try to change data type to string.
Your welcome buddy 
Hello. Right now it’s possible to store the array only via String datastream type. Another option is Location DS (for coordinates) - it is stored as [double, double].
We’re thinking about special Array DS, however, this is not yet finalized. Could you please tell us your use case?
Hi @Dmitriy, I’m using the virtual pin array to store numeric values obtained once a day for a 7, 14 and 28 day period. In addition to this i’ve integrated a circular buffer (CircularBuffer - Arduino Reference) to push the values each day at the same time so that I have the most recent value (yesterdays value) shown first followed by the previous days. Works really well. Once I iron out all the Blynk 2.0 minor issues I will post a project. Its an Energy Monitor that allows the user to input electricity prices and monitors electricity usage and will show a daily cost for electricity (or profit if you have a solar system).
