Lights failing to reply with acknowledgement. Can we get max retries and timeout as arguments?

[aredon]

I have a single A12 bulb and a Z strip that I am sending commands from the same script. I am running a script I call sunrise.py that slowly fades the lights in over a series of color commands. I'm very happy with it right now but recently it has stopped being reliable. At first I had issues with discovery randomly not finding lights but I mostly resolved that by just trying discovery again.

At the moment the lights (and by lights I mean, usually one gets stuck and the other keeps going) get through "initialization" and "phase 1" but fail to reach "phase 2". I have checked my network and as far as I can tell there's been no packets dropped or disconnections. Mind you this is completely random and most of the time it works fine.

I have also noticed that I can duplicate the issue (kind of - for both lights at the same time) by turning the router off when the script reaches "phase 1" and then I get acknowledgement errors. Is there a way I can wait for an acknowledgement and try to send the command again a certain number of times? I feel like that would drastically improve reliability. At the moment the script just ends when acknowledgement fails to come back so I added rapid flags to "hall light" because "window sunshine" is the more important one in this script.

Having been monitoring this issue for some time now I can safely say:

• The light is not disconnecting
• There are no wifi packet errors reported
• The router is not crashing, disconnecting, or dropping signal
• Signal levels are good

I'm not sure how I can tell the difference between a packet failing to transmit and just timing out but I would like to be able to modify timeout_secs & max _attempts. I suspect there is a timeout issue here.
