Hi,
a map attachment on IOS can only have 2 or less pins. So you will be limited by this.
I am also not completely sure what you want to do.
Do you want to send a map with two pins for the two device tracker you mentioned?
If you want to do that, you can use this template
{{(state_attr("device_tracker.jos_iphone","latitude") ~","~state_attr("device_tracker.jos_iphone","longitude")) ~ ",,"}}
for the first pin input on the blueprint
and
{{(state_attr("device_tracker.garys_iphone","latitude") ~","~state_attr("device_tracker.garys_iphone","longitude")) ~ ",,"}}
for the second one.(Just paste those in the correseponding textboxes of the blueprint). You also have to check Enable Second Pin
. This will place a pin on each devices location. Remember that you can not just send a map from homeassistant, you can only specify at which location you want to have a pin, the rest is done on the Iphone itself.
If you want to put a pin for each lightning you are out of luck. But you could place a pin for the last one (at least I think that it is the last one?) with this template
{{(state_attr("sensor.blitzortung_lightning_distance","lon") ~","~state_attr("sensor.blitzortung_lightning_distance","lat")) ~ ",,"}}
If you have any questions just ask!
PS.: If you are wondering why the templates have the ", , " at the end… this is to trick my own blueprint to accept this as a input. (If we would not have those the output of the template would be treated as a list but the blueprint assumes it is a string)
