Every night at midnight (precisely at 12:01, actually), I get a notice on my iPhone saying, “Lightning detected greater than 22 mi from [my weatherstation name].” This happens like clockwork, even when there’s not a cloud in the sky. Anyone else experience this? [IMG_8023]

Hi, this sounds more like something inside your house or around your AIR triggering a false positive strike. See Troubleshooting AIR Sensor Readings > Lightning

Do you live in an area with rate-based electrical meters? Do you or your neighbors have an electric car or something scheduled for a delayed charge time when rates are cheaper? Set-back programmed in your heat/aircon system? My three Airs sometimes record false lightning strikes when the well pum…

Thanks for the replies here. Do you live in an area with rate-based electrical meters?< Not sure what a rate-based electrical meter is, but we do have “smart” electrical meters that send out a signal so they can be read from afar. Is that what you’re referring to? Other than that, none of your …

Maybe not at your house but remember these little detectors ‘hear’ far.Sometimes a neighbour 100m from you has something that ‘sparks’ … Try turning it in steps of 90°, it isn’t as sensitive in all direction and sometimes you can find a dead angle.

Yup, I’m in California. Perhaps that’s what it is, some kind of spike when the meter flips over to a different mode at midnight each night. That or ghosts emerging at the witching hour. :astonished: I don’t mind the smart electrical meters so much. What I do mind is the water meters they install…

[image] rjfox: Every night at midnight (precisely at 12:01, Since it happens every night, I will suggest you open a ticket with support at support@weatherflow.com and ask that the data be examined. @dsj can ask the engineers to compare several strikes and this might help improve the firmware. …

@sunny do exactly what i do use a second Air sensor optimally positioned for lightning .note in photo temp ventilation blocked to prevent rain finding its way in ,its not used for monitoring temps etc,and yes horizontally mounted spent many months over the last two years siting it it for optimal d…

I Iike your approach. I suppost the unit is more sensitive in its normally horizontal plane. turning it sideways you might find a direction where there are no, or less false lightnings. In your case this direction is towards the sea and luckily no source of false lightnings in the opposite direction…

false lightning suppression is #1 on my wishlist Wish list (suggestions for additions are welcome), but apparently some people are strongly against it, even if it is an option.
