Hello,
When I change state of Shelly relay in quick succession (eg. on-off-on with 0.5 second gaps in between), then Shelly device transmits these commands with 3 second delay between each command.
As consequence on server side, I should receive all three commands in less than 2 seconds but instead I have to wait more than 6 seconds.
Is this default behavior or can I shorten delay? Thanks.
Edit 2023-11-13:
Solved 
It seems, the delay goes away after I force my server to include status code 200 to the response on Shelly device request.
