Can someone please explain to me the difference between the lightning distance on the left side of the screen and the right side column? I am confused since many weather stations show "Closet lightning time" as Sunday at 9:09pm. Also the distance between to the two highlighted areas are way way off. Any help in clarification would be great thanks.

There are two sources for lightning data on WeatherSTEM. One is from a national database (on the left) and then the data form the local sensor on SkyWeather (the ThunderBoard). One of the things for us to still do on this complex system is work out the correlation between the two. There is some real science that needs to be done regarding the local sensor. To give you an idea how complex this process will be, take a look at John's talk about tuning the ThunderBoard.

Oh, and please tell us about your stevenson radiation shield on the left of your SKyWeather station!

I didn't have a 3D printer and the cost of making a shield for the sensor was prohibitive considering you can buy one already made. amzn.to/2SuGNapWorks great especially after all the rain and hail we had over the last two weeks.

Awesome! I just ordered two units. This could be a good way of going. We don't make any profit at all on 3D Prints. We just produce them as a service for customers.
I'll report back on them!

OK, so I learned from reading this that the lightning strike info on the left side of the WeatherStem display does not come from my station but is from some national database, which explains why it doesn't match what my station is reporting. however, that does NOT explain why the data on the right has the wrong date and time! I invested in SDL's lightning simulator so I could test and calibrate my station's lightning detector, and just now I triggered to "strikes". I can see them in the log file:
Last Interrupt = 0x8: Lightning Detected 10km away. (13:44:19 - 2019/10/23) Last Interrupt = 0x8: Lightning Detected 6km away. (13:44:22 - 2019/10/23) Today is Wednesday, October 23. The display on WeatherStem says the latest strike was 6 km away, which makes sense, but it says it was on "Sun 8:08 pm"... Not exactly. Something isn't being reported correctly!!!

The time in the log file may be in UTC. If it is, does that make sense?

The time in the log file may be in UTC. If it is, does that make sense? BP No, not at all. The time in the log file is local time, and is correct. The time as seen in the display on the right of the web page appears to *always* be the same: "Sun 8:08 pm", regardless of when the strike (or test strike) occurred. Then after some timeout it resets to "Wed 4:04 pm", which is equally meaningless.
Besides, there's no conversion from UTC that can possibly change the date from Wed to Sun... !!!
It does not appear that the web page is displaying a time for the lightning strike that has anything to do with the observed data.

Ah, I missed the day. I'll look at this with different eyes. Please realize that WeatherSTEM is taking lightning data from a different source that our local lightning detectors. We will eventually be displaying both. Basically the local lightning data is just displayed locally and on Blynk at this point.
After looking at your garbage, this is stuff coming from your browser (SplashIDPlugin) and not from the forum. You can check my answer by posting from a non-chrome browser and seeing if it still puts a bunch of garbage in.
My browser (safari) does not and this isn't a widespread problem.

1) I understand that the left side of the display is from WeatherSTEM and does not come from my weather station. However, when my device detects lightning (or simulated lightning, when that was working), the display on the right in the box of messages changes to show that lightning was detected, presumably because SkyWeather sent a message about it. But the time and day are wrong.
2) I do not use Chrome. I use FireFox. So I am already using a non-Chrome browser... The garbage is intermittent. I've no idea what a "SpashIDPlugin" is -

I'm getting confused. Could you do a screen shot of what isn't being reported correctly as far as time is concerned? I think you are saying the SkyWeather display of the lightning and a display and weather stem don't match.

I discovered that I had saved 2 screen caps.
The one shows the display when there isn't a lightning event to show - now it shows "Sun 8:08 pm" - I find it "interesting" that this value is double the earlier one... This one shows the display when lightning was reported. As I described in my earlier post the time is shown as "Wed 4:04 pm". .

Thanks for the screen shots. I need to run this by WeatherSTEM to see what they are doing with this data. My main contact there, Ed, is on his honeymoon this week and so it will have to wait until next week.
