Main thing is if you spot anything that is not working as well as it could, or features you would like, let me know. Worst case, I would say no.
Otherwise, my drivers are basically a hobby now. They pretty much all do everything I need them to but I am always working on them a bit to make them better or as I learn new things while working on entirely new drivers.
Version 0.99 is now posted. Only Ecowitt users should see any difference as you will no longer need a fake MAC or API Key (they are hidden). For new users, the process is to add the virtual device, select the driver, then select the method you want (Ambient API or Ecowitt Local) and save preferences. If Ambient, it will then display the preferences for the MAC and API Key. Both get to select about the temperature, humidity, etc...
