I am interested in a WH57, Will this possibly be available through Ambient soon. I have never purchased directly from Ecowitt. If purchased from Ecowitt will this be a direct ship from overseas or shipped from a US warehouse?
If you have an Ambient branded console (like your ObserverIP) then you can't use anything but Ambient branded sensors. If you bought the WH57 from Ecowitt then it will only show up on your Ecowitt GW1000.
No telling when Ambient will carry the new stuff from Fine Offset. They may or may not ever carry a particular item. Resellers of Fine Offset stuff choose what they want to sell. No reseller of Fine Offset stuff has ever had a complete catalog. The exception is Ecowitt as they have everything. Because Ecowitt is Fine Offset. The Ecowitt brand was created as a subsidiary of Fine Offset as a consumer facing brand. Fine Offset does not deal directly with the consumer, as they are just the manufacturer.
The GW1000 has been out for over a year. Ambient still doesn't sell it. It is my favorite piece of equipment from Fine Offset. Without it I had to rely on the terrible ObserverIP. I can do so much more with the GW1000. It has allowed me to simultaneously run Cumulus MX, Meteobridge, Weather-Display and WeeWX. The soil sensor is another part that has been out for over a year and Ambient doesn't have it either. But the WS80 is relatively new and Ambient started carrying it almost as soon as it came out. So you never know what Ambient will do.
Ambient is the only reseller that has implemented a strategy where you can't use any other sensors but the ones they sell. If you had a Froggit or a Misol console, they would not complain about using an Ecowitt sensor, as long as the frequency matched.
If you order directly from Ecowitt then it ships from China. If you order on Amazon then it might come from an Amazon warehouse or it might come from China. If on Amazon it says that 2 day shipping (Prime) is available then it is sitting in a warehouse in your country (as Ecowitt shows up on multiple Amazon sites; US, UK...)
