I’m writing this on behalf of the team.
We wanted to update you on the resolution of some feedback we have received on a recent upgrade to the Sense monitor software.
This upgrade changed the way in which the Sense monitor resolved internet domain names (such as sense.com) into the IP addresses used for all internet communication. Every internet-connected computer has designated servers for converting names into IP addresses. These computers are called DNS servers. Without a functioning DNS server, the Sense monitor cannot operate.
The monitor software change was made to help Sense monitors operate on home networks without well-behaved DNS servers. Instead of trusting the DNS server provided by the user’s home network, which would typically be the internet service provider’s DNS server, the Sense monitor now sends its DNS requests to one of several well-known public DNS servers. It is our experience that these servers offer more dependable service than a home network’s DNS server. Additionally, misbehaving home DNS servers are usually beyond the technical ability of many home users to diagnose and fix.
However, we received feedback from some of our users that this change was undesirable, as they wanted a clear understanding of which third parties the Sense monitor was contacting, and what information was being shared with and retained by those third parties.
Our business depends on the trust of our users, and we hear and understand the concerns. This change to the list of DNS servers should have been included in the release notes for the monitor software update, but it was not. We will make sure to include any such changes in the release notes in the future.
The team at Sense has discussed at length how to proceed with preserving user privacy and transparency, as well as allowing the Sense monitor to function well in homes where the DNS server is absent or misbehaving.
We will take the following steps to address your feedback, while still giving new customers the best possible experience when installing their new Sense monitor.
We will limit our public DNS server to only Cloudflare’s server, known as “18.104.22.168”. Of the public DNS providers we examined, they had the clearest and strongest privacy protections. Cloudflare does not keep records, sell data, or target ads. You can read more about 22.214.171.124’s privacy protections here: https://developers.cloudflare.com/126.96.36.199/commitment-to-privacy/. Neither Google’s DNS server nor Oracle’s OpenDNS server will be used by the Sense monitor.
For those customers who want to rely solely on their own network’s DNS server, we will offer an option to suppress the monitor’s use of 188.8.131.52. To enable this feature on your monitor, contact firstname.lastname@example.org. This setting does not appear in the Sense app today, but it may in the future.
On home networks where 184.108.40.206 is inaccessible, the Sense monitor will fall back to the DHCP-provided DNS server. Thus, if you wish to simply block access to 220.127.116.11 for all devices on your network, or for the Sense monitor explicitly, your monitor will continue to function using your DHCP-provided DNS server.
These changes will take effect within the next few weeks, as we release new monitor software.
Thank you for bringing your concerns on this issue to us. We want to make sure that all our users know that their voices are heard. We are committed to offering the best combination of privacy and dependability for our users, and we believe that these changes hit that mark.
