Well, i hate having to do this (and writing about it) but when (to me atleast) i didnt get a detailed explenation what Google Analytics is doing in the HC2 and how often it is used etc, i had to look for myself.
I do NOT use Google as DNS in my HC2, i use my gateway.
I used Debookee to analyze the traffic setting my router as "Gateway" and my HC2 as "Target" and this is what i found.
Summary.
This is what a HC2 does every hour, of every day.
HC2 does:
5000! DNS requests to Google (4924 times to be exact)
500 HTTP/S Requests to Yahoo and Fibaro (350 HTTPS requests to Fibaro and 150 HTTP requests to Yahoo for weather)
5 SSH Requests to Fibaro
This stacks up to a grand total of almost 130 000! Requests every day!
To me this is not just "Gathering som data to analyze system performance etc".
http://forum.fibaro.com/index.php?/topic/21144-google-analytics-included-in-v4080-update/?p=86789
That can be collected 1 time / day or week.
I understand that some use home.fibaro.com and that needs a connection, but i use DDNS and that updates only when necessary so i can't see any use for all these DNS requests.
And as Fibaro has SSH access and the box constantly updates Fibaro via SSH and HTTPS requests it all seems like ALOT of traffic.
! Please correct me if I'm wrong / misstaking etc, I'm not a network admin with 10+ years of experience !
Here are the Debookee captures if anyone is interested..
