Hi! I am a happy Pilot-user.
But..... as far as I can oversee Location Services is only functioning when you have mobile internet (3G/4G), when you have wifi only then it is not switching (the switch in Domoticz).
It seems that it's only functioning when it is online when you cross a border of the set location. I you are using wifi at home (without mobile internet) and you leave the house, it is obvious you have left the wifi-zone before you have left the location based on GPS. So at the moment you leave the location it will not switch.
Even when you enter another location (at work) and a new wifi zone (at work) it will not switch. I expect for the same reason. So that means that if your switch is reporting you are at home and you (only wifi-user) are work it can (and will) report that you are still at home.
Correct me if I am wrong but this leads to the conclusion that Location Services is of no use if you do not have mobile internet or weak mobile internet when you cross a border of your set locations.
