I have the same issue, just received 2 Sonoff DW2 WiFi-L, registered them in the ewelink app, and bam, immediately offline and never seen.
I can ping them both, although the ping response times are shameful (from 300ms to 1200ms, when other devices are 1ms)
I also allowed 11b devices on my wifi but still the same. Also I can see they are reaching out to eu-dispd.coolkit.cc every 10 minutes
I opened support tickets, but did anyone here fixed this issue by themselves?
Dear StephenJ, Can you help me, please?
My brand new DW2-wifi goes offline randomly after turning on and stays that way until reboot, despite being at a close range to the 2.4ghz router. Manual open/close the device doesn’t bring it back online. It has fresh batteries and, when online, displays full wifi signal on the ewelink app most of the time. Appreciate help into making this device usable. Thanks
