Like others my dongle E network becomes completely unresponsive ie all.devices go offline.
Today i have time to test and sees if it’s a repeater issue. (I added IKEA tradfi repeaters to network about four months ago )
If i can’t work it out Would you recommend migrating to sonof dongle p? I have a brand new one. I have 40 ZigBee devices. And assume I’d have to repair ? The guide doesn’t specify if you need to re pair for this case.
