OK, so the moment has arrived...

I have the WH57 in my hands.
 [ You are not allowed to view attachments ]
As you can see and as expected its the same size package as a normal temp/hygro sensor (wh31)
It does have a LED underneath the lightning symbol that flashes red when it transmits.
I don't know if this will also indicate a strike at the time of writing this.

The sensor appears to have some settings that users can control. As of now I have chose to leave them default as I received it.

The GW1000 systems in my house have all seen it automatically and added it whilst the HP2551 so far has not.
I am in dialog with Ecowitt but I believe that the firmware is not yet completed that allows the integration of this sensor.

Any detections yet?
Weather is looking fairly calm at the moment in Southern UK so I am betting we will have no thunderstorms for ages!

I shall be curious to see if there are any false detections as I know that's the real issue with detectors

From my testing, it seems there is something in place to avoid false positives. I also have a Strike Alert HD3000. If I put them both side-by-side and hold a TV remote in front of them, then press a button, the HD3000 triggers an alarm, and the Ecowitt LED flashes, but nothing registers via the dashboard. If you hold the TV remote button down for a long period of time, the Ecowitt will eventually register a strike. So, it's definitely trying to filter out unwanted noise.

Hopefully, they'll be a chance for some convective weather next week, in the form of showery troughs moving in from the W/NW - dragging cold air aloft.

mauro63,
Do we know from Ecowitt if it can be used laying down? Would that inhibit its ability to determine distance? or to detect as well?

Also where did you get that clear globe? Is that from Ecowitt too as an accessory? Or is that something you improvised?

Since the WH57 Lightning sensor is the same size as a WH31 / WH32 I would think that a RS-00001 or other radiation shield might be sufficient to protect it from the elements. That globe though does make it look sort of interesting. It has a certain wow factor to it. I'm not sure though yet how I totally feel about it because I have some questions about how it works, especially laying down. I also wonder if that globe makes it hotter in the summer and how that would affect the electronics.

Hi Galfert, the little aerial inside the sensor has a little directivity, so I decided to put the sensor outside on horizontal position, at the moment the upper of the sensor is pointed to the North
the globe, that is absolutely improvised and not good for next summer, so only for the first tests, but it's waterproof, give me the ability to rotate the sensor and I can see the position without unmounting it
sorry Galfert for my English  :sad:

Hi,

the Ecowitt will eventually register a strike

are you allowed to show us how the lightning is shown in the Ecowitt-data string?
Especially the lightning_time - will this a unix-timestamp (1578667249) or just the ASCII-time yyyy-mm-dd+hh:mm:ss (2020-01-10+14:35:38)?
And - as far as I was able to read the count of lightning will be stored in a field called "lightning_num" and the distance probably in "lightning_dist".
Is this right so far?

I'm writing a program to connect a FOSHK-weather station to smarthome-systems via UDP and would like to prepare this already for the ligtning sensor (which I'll buy as soon as available).

Regards, Oliver

Absolutely right, these tests are necessary about your questions, it's possible that the vertical position could be better, or not
the globe is absolutely for this start, the next step will be a white tube, horizontal or vertical, I don't know
the most important thing does NOT use metallic parts for bracket or other components near the sensor

Its clear from the settings that they expect a difference for indoors versus outdoors reception.
Whether that's for the interference algorithm is unknown.
I had not considered direction either.

Lots of questions to work through!

I do not know much about radio frequencies/antenna design. If you added a faraday cage to the bottom half of the ball, would it block ground level interference and only detect radio waves from the sky?

Maybe it would be a better design to set both buttons low for "low sensitivity" and both buttons high for "high sensitivity"? Up for "outdoor" and down for "indoor". If you are holding the sensor in your hand, the top part is pointing to the outdoors.


We have been discussing a lightning symbol flashing on the console display for a set period to indicate lightning activity in the detection area.

Are you referring to the "Lightning icon appears when then Dew Point exceeds 70 oF, which signifies conditions may be possible for lightning storms to form in the area."? Sounds like a good idea.

The GW1000 systems in my house have all seen it automatically and added it whilst the HP2551 so far has not.
I am in dialog with Ecowitt but I believe that the firmware is not yet completed that allows the integration of this sensor.

Could they add a "Closest" section? If the closest strike is 1mi and the last strike is 2mi, then the storm is moving away.

Good idea!
I will suggest that to Lucy.
It could be as simple as a arrow to show strikes getting closer or moving away

"Rain" could be removed from "Daily", "Weekly", etc.

Quick question; on the GW-1000 app, how come I can see  'Day Wind Max' on that screenshot? I don't have that on mine.

I have Day Wind Max on my WS View. Perhaps you don't have the latest version of the app, or you don't have the latest firmware on the GW1000. My WS View app version on Android is 1.1.36. You can see your app version by going to device settings, Apps, and then finding WS View from the list of installed apps.

Does it really do that?? T-storms can and do form at all various surface dew points, including below freezing.  :roll:

I read that you said you had the latest version but I wanted to know if the latest meant the same or different from mine. Also I'm on Android. Are you also using Android or iOS? I don't have a real answer....I'm just trying to figure out differences that might lead to some revelation.

That icon has already cause many to think that a lightning sensor is built in. Now that a real lightning sensor exists I wonder how many more people will be confused.
