Ring app connection question

Recently i installed a PiHole DNS in my homenetwork to know more what my devices are doing.
Since yesterday i see that the Ring app connects a lot more than other devices or apps.


Here you can see that Homey does 300 dns queries in 10 minutes, that is 1 ipv4 and 1 ipv6 querie per 5 seconds.

[i had another screenshot, but i can’t post it due to forum restrictions]
The queries go to api.ring.com

Is this normal behaviour? I restarted the Ring app and restarted Homey, but this doesn’t reduce the DNS queries.

Here is a summary of 10 days opendns.

This is a network wide summary, homey rules the top 5 queries.
