I have 3 groups which are door, window and garage. I am able to get notifications when I add a single group but not when I use multiple groups.
Please review code below rather not setup separate notifications for each group.
service: notify.mobile_app_my_iphone
data:
title: Door or Window was opened
message: >-
This was opened: {{ expand('binary_sensor.door_group',
'binary_sensor.windows_group', 'cover.garage_doors')
| selectattr('state', 'eq', 'on')
| map(attribute='name')
| list
| join (', ')
}}
