I don't know about gizmos that do it Leon, but this is what I use:
https://www.lightningmaps.org/#m=oss...2;dc=0;ts24=1;
That and my Raspberry Shake and Boom (it picks up lightning within about 400kms - but you have to interpret the signal). I use the web page to identify how far away individual strikes are from the RS&B.
