core: Netgear Integration - Traffic Meter Data not working

The problem

I tried the new feature which would supposedly retrieve traffic meter data from the Netgear router but the entities do not update and instead, I see “Unknown” as value. See image.

I tried rebooting my router and restarting Home Assistant but it did not get fixed.

I saw some logs generated at the time Home Assistant is started. Check it out below.

What version of Home Assistant Core has the issue?

core-2022.3.3

What was the last working version of Home Assistant Core?

Never
