I believe this 'Fatal Signal 11' error is unfortunately more of something related to Domoticz side, not the plugin itself. Please check: http://www.domoticz.com/forum/viewtopic ... 11#p165132 and https://github.com/domoticz/domoticz/issues/1891 As far as i know no solution is found yet. As i see you are using stable 3.8153, and what platform is it? Raspberry Pi? I am using the plugin on 3.8153 on Synology and Windows without problems. You can try without the google Key, leave that option empty and try again. So that we can maybe understand if it is a google api or life360 api based problem.
If the plugin is no-go and you still want to use Life360 presence, you can always use https://www.domoticz.com/forum/viewtopi ... 60#p144142 bash script of this plugin. It is missing Battery and Location options.
