First I have not head of motorbility allowing installation of 2 chargers at the same address
Where did you hear about that motorbility offer?
More than one person can login to the same Ohme app setup I hear
You say
{Looking at the unit last night, you can only have one user and one vehicle on the app which Ohme have confirmed to be the case.}
It seems you already now have the answer you are looking for or am I missing something
