Network Binding incorrect reported response time

I’m not sure if I am doing something wrong but I am getting high response times from local network devices. If I ping from the raspberry pi to the device I get sub ms response times, yet from the network binding I am getting high values. Anyone having issues with the network binding currently?

  • modem, router and wirelessAP are all local.

This is via a ping command:

Did you ever get to the bottom of this? I am observing the same issue. It appeared for no apparent reason after working properly for many months. My setup pings my router, my ISP, and google. All of the counts jumped by about 20 ms one day back on Nov 28 of 2022, and have stayed elevated since. But, as you describe in your post, my cmd line pings are much lower than what is reported by openhab. My router ping times are usually sub-millisecond, but openhab reports around 20 ms. My ISP ping times are typically around 21 ms, but openhab reports around 40 ms. And I can ping google’s DNS at about 30 ms, but openhab reports around 50. Something is adding 20ms to all of my pings.
