Since I have my Hubitat notifications are not working. I've had contact with BobbyD from support about it and he cannot find anything wrong with it.
1x Hubitat HUB
2x Xiaomi Pocophone F1
To be clear, my wifes Pocophone works great with notifications from Hubitat.
Now since I finally got to the point I actually have a use case for notifications I started installing Pushover, since I don't need Hubitat app for notifications. So I registered and then it comes to the point where you have to register a device (see screenshot). It gives an error about not being able to register at Google Play Services. Now I have Googled that error and found not many results, just one Reddit post saying I have to clear the data of the Google Play Services app. I did that, no joy. Rebooted phone, cleared data again, no joy... So I'm in the dark at the moment. I will test Pushover on my wifes phone when she gets back home (I bet it works right away though). If any of you has any experience with this I would love to hear a sollution (without factory resetting my phone please )
Ok, since I'm not good at waiting... Patience is not one of my virtuous.
I went on looking in another direction. The main difference between my wife and I is that I have a paid Google business account (G-suite). So I logged into my G-suite admin console and went on wondering around in the world of million settings it provides. After a while I stumbled upon "device management" > "app management" > "Manage apps for android devices" > "Manage whitelist app".
So I pushed the button and got a list of 11 apps. I added Pushover and the Hubitat app and now it's working. Though I don't understand why these apps need to be on the whitelist while Whatsapp, Telegram and a lot of other apps can give me notifications on my device without being on the whitelist.
It could be that it is dependent on any of the other million settings in G-suite. I don't know. To be honest, G-suite admin console is imho a sluggish hell to go through. If I could migrate to some other service I would right away, but I don't think there is one. (tried MS 365 once, didn't work for me)
I ditched g-Suite 2 years ago because of crap like that. As you said, using the Admin console is like talking a slow stroll through the ninth level of hell. Then, the constant barrage of "[insert app name/service name] doesn't work with g-Suite accounts" really ticked me off.
I have a paid O365 account for home and one for work and it works perfectly for my use cases. Microsoft has come a LONG way in terms of Android support for the apps.
