Since last week the Xiaomi V2 and lightbulb are offline in the Yeelight app.
The other 10 colour LEd bulbs and 4 led strips are still online. All the 6 sensors and clickers don’t work any more since the gateway is also offline. It was stable for 8 months. All the devices are updated to the latest firmware release.
The IPS is KPN Netherlands Wifi: 4,2 Ghz. After a reset of the router 2 devices went offline.
Yeelight: server China
Reading more posts I Pinged PING ot.io.mi.com 188.8.131.52 and an other address 184.108.40.206.
Tried with two different smartphones One+ 5T and Google Pixel 2 with latest Yeelight app to make the connection.
The bulb and gateway don’t make the connection to the server. Message is take device closer to router. Than the time-out message comes. Try again. Did this more than 20 times and resets. No success.
