Hiho,
after my flows grow I realized that more and more often after deploy button my raspi 3B+ loses WifFi connection. I have to wait for reconnection and "check changes" ... than deploy again. I guess that it has to do with the size / complexibility of flows. Is there a way to avoid this ?
What type of deploy are you doing: Full, Modified Flows or Modified Nodes?
If Full (the default) have you tried the others?

Thanx @zenofmud ! I totaly missed that option! Mine was set to full. Since I use "mdified" it works again!
