Just to briefly revisit this issue (ok, I guess more of a feature request than an issue?):
Do you by chance know if the planned ET-based weather algorithms you mention above will be compatible with the current hardware, to be added via a simple firmware update, or will they require upgraded hardware to implement? (if it’s possible to know, currently) Is there any (reasonable) chance they will require new hardware, or are you relatively confident the new features will be made available for the current platform?
