It was working perfectly fine until 2 days ago where all my Yeelight didnt work. My entire house uses Yeelight and sensor. Please help to fix it.Always show as offline. All Yeelight bulb is also on the latest firmware. There was no firmware update in the pass few days anyway. I connected to Mainland china always, now any server also detect as offline.
Maybe I can provide more info since I use all Xiaomi products. All the below devices are offline:
Yeelight bulb
Yee color light bulb
Wireless switch
Motion sensors
Gateway V2
Mi humidfier
Mi door sensor
Mi temperature and humidity sensor
Practically, everything goes offline and only the Yi CCTV is working.
I do see all the devices in my router menu. Just all show offline in Mihome app.
I have no idea what went wrong, lucky I still can use manual switch to control the lights. I will try to reset my entire network next. Factory default the router and resetup everything, Hope it works. Else I am out of idea.
I went for my vacation and when I got back, everything wasnt working. During this period of time when I was on vacation, there is nobody in my house.

Previous was OK on Note 8. I try now in Note 3.
MI ID: 1755673913
All was OK 10 days ago. Last firmware updated 10 days ago. And suddenly 6 days ago in the morning appearing offline. I try reset many times, I did reinstall software on other phones. Then I try all the servers US, SG, China. I did fixed band and fixed IP on router. But nothing changed. Only what I can PING it the lightstrip.
For the moment I solved my problem. I moved the Yeelight lightstrip in Guest Network on my router where the Yeelight cannot access my internal network. It is possible the firewall from my router to be in conflict with Yeelight lightstrip and reject it or something else.
Maybe this solution can help other customers if their router accest Guest Network.
I received in 19.12.2017 the package with 2 pcs Yeelight lightstrip. I install it one pcs on US server and instantly I did firmware update. After that I play with it, I did create scene, then I connect it to Google Home Assistant. In the next day I see it offline 2-3 times but just for 15 seconds (nothing important). All was OK until in 22.12.2017 in the morning from when remain only offline. I try 2 days from time to time and was only offline. And then I did delete it and I cannot add it again for 5 days until I connect it on Guest Network. I don’t remember if I restart router or not, just before to be continuous offline.
Answers are:
2-3 times for 15 seconds;
Yes, everything as before (except from the wear smartwach, but that did not work neither before, I think you know that)
Are a lot of devices: desktop, 2 laptops, 3 IP cameras, PS4, printer, NAS, switch, smart tv, router extender, 2 smart plugs, smartwatch, thermostat gateway. All of them are on fixed IP on router.
The second lightstrip is still in the box untouched .
