This has happened twice in the last few days, monitor goes offline, I go out to the panel, connect with the app and force it to reconnect to wifi and then it’s back online. Both times it has gone offline at exactly 3am.
None of the other ~30 devices on my network are having any problems. Sense support has not been helpful so far. Anyone seen this?
If anyone else runs into this… The problem is that sense must have decided to hard code their own DNS into the firmware (22.214.171.124 and 126.96.36.199) if the monitor isn’t able to reach either of those IPs on UDP port 53 the firmware update will fail, revert back to the old firmware and fail to reconnect to the internet.
On my network I have UDP port 53 blocked and force all devices to use a local DNS server so I can track what they’re doing.
The fix was to temporarily allow the sense monitor to get out to the internet on udp port 53. This is the first IOT device I’ve run into that does not honor my local DNS over whatever is hard coded, so I hope sense is going to fix this.
