I have recently noticed mine can sometimes retry 2-10 times. Could you have a possible networking issue? I know my setup is rather full… but otherwise seemingly glitch free.
But now that I think about it, it has been abnormally persnickety connecting the hardware, and maintaining connection to the App (seems to stall out for short periods of time), since I last updated my Local Server (0.41.3-SNAPSHOT) Hard to confirm, as I was also in the middle of lots of other library changes on the Server RPi for other forum user troubleshooting.
I really need to stop compromising my setup just so I can answer new user questions
