It appears that the folks at WeatherFlow push the update to the hardware. If you look up at post #14 they say that they have over 24 thousand devices to update and it will take a few days; however that was 10 days ago.
@eric should be able to give you more info.
Yah was just wondering I just installed mine and was looking for a way to update the firmware. But found this thread.
Ok, glad I found this thread. Was just looking at the firmware versions and I have older versions still. So will just be patient. As far as I can tell, lighting count and distance are good.
Rain numbers are also starting to look a lot better than they did a year ago as well. Now only off by .05" on average now.
your hub has the latest firmware 170.
Ever since getting a replacement unit that got updated to 155 the lightning reporting has been laughable at best!
Quite simply the distances are purely random. I do have other lightning detectors and my original tempest was much more accurate with distance. At this point it’s about as useful as turning on an AM radio and hearing crashes, yep! It’s thundering (somewhere)! 
I’m not expecting it to be as accurate as a ten times the cost Boltek, but something is up now.
I’m getting the impression that weatherflow decided to change the way lightning is reported. It might be that it is more sensitive now, but therefore also picks up more false lightning. However they suppress the lightning, when they don’t think it is likely to have a thunderstorm. So you don’t see the extra false lightnings when there isn’t a storm. But this is just speculation, perhaps someone from weatherflow can comment on this.
Well now I can say that this device cannot be trusted for lighting - at all!
A cell popped up with lightning close enough to hear thunder. I get lightning alerts for any CG activity within 30 miles of my location and was alerted beforehand. TEMPEST shows ZERO strikes with last activity 2 days ago!
Also it did rain briefly, more than enough intensity to trigger the sensor and NOTHING.
I’m on FW 155. 134 seemed to at least produce faithful results. My unit was replaced because they could not push updates to it. It was working as good as it could ever. Now since this “fix” the results have been sporadic if not just broken. The prior unit over reported rainfall and this unit is grossly UNDER reporting even with raincheck. Perhaps the calibration from the old unit carried over to the new OR the newer firmware has reduced the sensitivity of the haptic sensor?
Either way, in this condition I’m just going to say this unit is broken. Thank goodness I have multiple stations!
