It could be, depending on physical placement. This particular model operates on 2.45 GHz for its microwave component, and that could definitely interfere with Wi-Fi or zigbee which operate in an adjacent band… (To interfere with Z wave, it would have to be pretty much right on top of it).
There have been multiple reports of this issue, and in the UK these devices can only be deployed “with restrictions’” meaning The installer has to test to make sure they aren’t interfering with the local Wi-Fi network.
If you have them all over your house, then you are more likely to have a problem, obviously. And if you have any close to the hub, then that’s more likely to be a problem.
So I would say there’s a potential issue, but it just depends on the exact physical placement of all the devices.
I wouldn’t think adding Konnected would make any difference if that’s what you’re asking. If you have trouble reaching the specific Konnected device you might just need to physically move it to a different location. These kind of interference issues always come down to very specific placement.
