It sounds like you are using templates incorrectly.
You should read this…
Your question about reconnections is impossible to answer unless we know more about your connection method, so we need to see your (correctly formatted) code.
hi peter right now i created a template,and inside i created 2 devices.these 2 devices read 4 data from one inverter 4 data from the other inverter,and send them to the blynk server.
when I configure the graphics of a device I set the virtual values of a device, it also changes the values of the other and I can’t view them together :(.
so I have to use 1 templates with one device and one other template with an other devices? Thank you.
