Just received 3 units of DW2 and configured them.
- The first one is short circuited on the battery, it pairs, but the magnet does not work and the battery gets hot. Trying to convince the Sonooff oficial store on Aliexpress that this is not normal. It is a shame, the person that is answering my messages does not know what a short is. I'll have to open a dispute on Aliexpress since the person is stalling me.
- The second one is disconnecting from the app at some periods and for no particular reason reconnects again. Already changed position with the second unit (considering weak signal) but the problem remains.
- The third one seams to work fine for now.
- Tha two that as working do not show more than 2 days of logs and it do not report all logs. Since it is a security device, the minimum is that it is reliable when it opens and closes.
Wait a week or so until they simply stop responding, or take HOURS to reflect a door open/close. Im sorry to say, but every DW2 I purchased, was wasted money.
I have been facing a similar problem like yours now it's fixed I have used this website
I have the same problem. DW2 sensor cannot connect to router tp-link ac1200. always unsuccessful. but when I connect with hotsport mobile phone no problem. does my router not support DW2 sensor. anyone can help.
I'm having the same issue about opened/closed status... It's taking too many time to update the open/close status. I bought one to test in my security system.
I have another sensor from Tuya that is working fine and without to configure the AP to 802.11b. It's running on other WiFi patterns!
In this case, Tuya/Smart Life is winning...
I have a new problem my DW2 worked perfectly for 24 hours after firmware upgrade but now its always offline
I have unpaired and paired it on 3 different routers with 802.11b only but no success
I can see the device taking an IP address from the DHCP server table but its always offline on ewelink app
Any bright ideas???
both my dw2 has been offline since 2am .
I left the batteries inside and today its back online and working perfectly.
@Txetxu you were right they maybe blocked DW2 macs by mistake
