The notifications seem to be stuck in HA and all come at once all with the same time stamp. At first I thought it was the phone going asleep.(Android). But on that same phone the other apps are notifying with the correct time stamp.
As I sit here sending a test notification to my phone. Nothing is coming and there are no errors in the log when I call the script.
I just rebooted and the notify is working again. I suspect until tomorrow.
Do you have a timestamp built into the notification?
I intentionally put the time in my messages because of internet going down and then getting all at once. I get the time the messages was first generated by HA.
If I delete the home-assistant_v2.db will that clear any data base errors and allow ha to send notifications as there happening? The timestamp band aid is a great idea.
