Hi, Tony,
I just set up a new station. The good news is your data is safe and given time WeatherFlow can help restore you old data.
Boris has shown little interest in WeatherFlow except to initially support the Sky/Air. He has ample time to ask questions and receive the necessary information to add support for Tempest.
As for “hanging your dirty washing out in public” don’t give it a second thought. If Boris is the type to abandon an entire group of supporters because of one comment, well, everyone can form their on opinion. Just beware of those here that do as they accuse of you.
