a few things:
the GW1000 running without any other basic sensor should show
only Indoor as it did with your first live data posting - where your GW1000 was still station 3.
MB usually picks up the GW1000 properly even when run without an external sensor -
I know of a configuration where it is GW1000 plus two WH41 (PM2.5) sensors and it works fine.
It seems that you have changed the station # meanwhile
And now, after you changed the station # (3 to 2), so you say, the T/H/P data of now station 2 is displayed differently ...
strangely it now shows three different lines, one per sensor, where it should be one line with three sensor data only.
So it cannot be ruled out that the position as a station plays a role (e.g. 1st hardware, then software or whatever)
the way the logger is programmed now.
See also @Wim's suspicion.
Did you configure it the same way as station 2 as it was done when it was still station 3 ?
By the way, changing more than one parameter at a time in a test or error locating situation is counterproductive, as you can't say, what produced what.
Again, that it doesn't show the lightning is not astonishing if the GW1000 was reset, lost power or so in between.
as @Wim already indicated
That's why I proposed to create fake strikes. They will be recorded and provide a test base.
(and can be deleted later on)
If you don't like to have the test strikes at ecowitt.net, switch off the sending to ecowitt.net in the GW1000 - but then it will become more difficult for you to detect the strikes. You can use the WSView app live data for documenting the tests, fake strikes, with screen copies and switch the GW1000 postings to ecowitt.net off.
So I propose
make a database backup (create a backup event in Services and have a USB stick [FAT32] inserted for the backup)
and a backup of your configuration (System/administration)
test scenario 1
a) to go back to the original setting (GW1000 = station #3)
b) create fake strikes
document a) and b) with screen copies, specially the live data view (min/max only if it appears

)
-----------------------
test scenario 2
a) if possible, just for 5-10 minutes, configure the GW1000 only (=no other station) as primary station as see what it gives (screen copies)
check live data
create fake strikes
and come back with the results here
