Unless you monitor the network it is very likely that it is pinging a Chinese server.
Many years ago we bought a treadmill with LCD screen and Android running on it with a browser and other stuff. Connected it to WiFi and were happy.
A couple of years later I got a Ubiquiti edgerouter, configured it and decided to check its deep packet filtering. It started showing me an odd Chinese domain being pinged periodically, like every 5 min. Don't remember the domain but it was some Chinese search engine/portal I had never heard of (not Baidu). It took me a while to figure out that it was the treadmill that was doing this. At which point I had to just disconnect it. I have no idea why it was doing what it was doing and what data it was sending and if I was running a backdoor in my home all this time.
Point I'm trying to make is, don't assume. Mistrust and Verify should be the modern day mantra for Internet connected, especially Chinese, devices.
