I started my new tempest weather device today. It is working properly. For the last two years I was using the old weatherflow two device setup. When I use the weather app ‘history’ it shows only todays data. How do I merge the last two years of data with the current data?  
Thanks, Greg.

I do not know if it is possible but I know the only way to find out is to ask support.  
Use the link at the top of this page and open a support job.  
If a Tempest is replaced with a Tempest the history can be merged.  
I do not know if the history from a Sky and an Air can be merged onto a new Tempest.  
Cheers Ian 🙂

Searched in the Help section: 47 results for “merge SKY data into Tempest” Hope this helps.

### Merging Data from Legacy Smart Weather Stations to a Tempest System

Data **cannot be merged from an AIR and SKY device to a Tempest device.** If you want the historical AIR and SKY data on your station, you must **attach the AIR and SKY** to the new station Hub. **Then, when the legacy devices are in place, we can recover the archived data to those devices.** You don’t need to continue operating the legacy devices, but they **need to be added to the station Hub** as placeholders for the historical data.
