Howdy,
I was having issues with my WLL a couple years ago (It wouldn't reset "Storm Total" rain amounts). I checked online for a way to update the WLL firmware and found nothing. I finally reached out to the Davis Instruments help people and they pushed an update that fixed it. My WeatherLink Live now reports:
Live Firmware Version
Firmware Version
May 24, 2023
Radio Version
0.5.4.37
It's working fine now, so I haven't been in a big rush to update it again.
That said, it would be nice if there was a cheat-sheet on the Davis WLL website listing what the versions of firmware are and what the differences are between versions (fixes, improvements, deletions) and a way to intentionally update it.
