From my Pi Hole it appears the remote mesh is trying to get to Baidu. Why?
I found a explanation about some other router was doing the same thing just to see if the Internet was alive. See:
Seems that if it wanted to check it could ping Google instead but going to a Chinese site immediately raises suspicions f malware.
Hey lloyd!
I plugged your topic title into the Wyze support Ai to see what we could see. 
Interesting. Thank you. No doubt the software was probably produced in part in China hence the contact Baidu, but still concerning that the AI doesn’t have any information that Wyze has looked into this and maybe thought about changing it. But I can live with it.
I have the same issue. I even opened a support request with Wyze, submitted logs and did some extensive troubleshooting for them to just bitbucket (ignore) it.
They did mention that it could be something that is connected to the Mesh router, which I have investigated and, yes, it could be.
With that, I have taken a few of the devices I have (the ones that I have multiple devices of connected to different Wyze Mesh routers) and connected them to a different access point that is not a mesh router and that I have complete control over) and they do not connect to baidu.com.
In addition to this, I did a wireshark trace and was only able to see the traffic was coming from the mesh routers (I have 4). So, I started poking around in the Wyze App because I figured they are not getting the DNS from DHCP. From this, I did actually find a place in the app where you are supposed to be able to manually set the DNS for the Mesh Routers. Well, that has been a complete fail. It doesn’t work.
At this point, I am just going to toss this junk and find a mesh that will allow me to set the DNS manually (I have an ASUS router, so, probably going with their AIMesh system).
Wyze has shown me that they truly do not care.
As an update, I did purchase a new Mesh system (Not Wyze). After installing it, I did a ‘pin’ reset on my Wyze mesh. After I did this, I setup the main Wyze mesh router and was able to configure it to use my Pi-Hole router for DNS. I’m thinking ok, maybe support was right…I monitored it for a couple days and I had zero baidu.com DNS requests. Now, I am thinking that support might have had a clue. So, I add the first satellite router. Within minutes, DNS requests to baidu.com coming from the Wyze mesh.
Ok, maybe this is just a random thing. I remove the power from the satellite router. DNS requests for baidu.com disappear. Hmm, ok, strange. So, I do a ‘pin’ reset on the satellite router and add it back in…and…baidu.com shows back up in the DNS requests.
I had no devices connected to the Wyze mesh, and, DNS on all other devices was not pointed at my Pi-Hole router.
So, this is 100% a Wyze issue. There is NO WAY to deny that the requests are coming from the Wyze Mesh hardware. Zero, zippo, none.
Does anyone want 4 nodes of a Wyze mesh heater? (because all they are worth is generating heat)
