First be sure that you have filled in the user key and token api key under more (three dots) > Settings > Pushover Notifications. If you don’t use groups in pushover you can keep the group key field empty.
In your flows where you want to use Pushover fill in all fields. for Emergency retry interval and emergency retry expiration just fill in 0.
With Pushover you can select the message priority, this will be defaulted to normal, but there are also other priorities one of them is Emergency.
For example, Homey knows you are away from home and your motion sensor triggers movement, you could use the pushover card and set the priority to Emergency, with the emergency delay field you can set a certain time in seconds, this means that it will re-send the notification every XX seconds until the user has acknowledged the notification or if the set emergency retry expiration is reached.
