I have a Froggit HP-1000 which is the same as the Ambient Weather WS-1001 Wifi. After reading many different threads here, I downloaded the 2.2.9 update, edited the main.ini to change the frequency to 433M, and edited update.ini to keep the database from being deleted.
The about screen now says 2.2.9, frequency is 433M, but neither the indoor nor outdoor sensor is detected. It also deleted the database so that data is gone, but it is still on Weather Underground so no big deal. Wifi works just fine.
I have used the Reregister Indoor and Outdoor transmitters, neither made a difference. I have tried factory resetting, that didn't work either.
How can I get the sensors to talk to the display?
