I am pretty new to this business of backyard weather, and recently purchased the WS90 kit, a couple of moisture sensors, and the "lightning detector". I knew before I purchased it that many folks would like to toss it against a wall, but I took the chance hoping things would be different for me. Seems I was wrong. I cannot confirm if it works with actual lightning, because I have not had many storms roll off Lake Ontario this week, but I can confirm like many others, that I seem to be getting false positives. That was expected, and no matter the DIP position, they just happen. I can accept a couple, but when they do happen, and I have had many. They are always 14km away. Always. I searched high and low, but other than the typical false positives, and dip switch configs, nobody else has mentioned what those distances are when they get the false positives. What has your experience been? Is it always the same distance? When it does actually detect "REAL" lightning, do these distances change??
