I had a tower sensor and 5-in-1 reporting to MBW through The Acu-Rite bridge passing through MeteoBridge. After several MBW outages just as interesting weather was approaching the northeast, I fell back and am now using an Acu-Rite 1035 console via USB to feed MeteoBridge.
If MeteoBridge can't sniff MBW traffic (because it is down or has DNS resolving issues), it cannot read your sensors to upload their data.....
