Ok google switch on lamp but the lamp switch off

I think he’s read this:

Blynk + IFTTT - details Guide how to connect both

in that case , nether Blynk API or IFTTT can handle that right now. but i think Blynk can change the API which in case you have set the PIN type to Push button that will not retain the status 1. or you can have Tasker doing that by sending two requests " 1 > 500 ms delay > 0"

and ignored the bit about using Tasker to do this and just thrown it in the IFTTT body instead.

What could possibly go wrong?
