I dont know about others, but sometimes I am not able to check my phone, or be fully present in a conversation that I’m part of. Maybe I’m concentrating on work, or driving, and not able to look. It gets distracting when my phone is constantly buzzing and chiming for 5 minutes straight. Muting the chat can help, but if you forget to check it, or get added to a new one, you can’t really do anything about it. I just want to be able to get notified once that the chat has new messages, decide how I want to react, and then move on from it. Is that too much to ask?
No. I know it was something I configured in FluffyChat, and for that to work it must have sent the configuration to the Synapse server; my account is on matrix.org. This is in the Notifications settings of FluffyChat:
Tusky (Mastodon) can also use ntfy, so Mastodon server(s) must support it too. Ring, most (all?) of the Futo communications apps, like Circles. I think ntfy is common for the fdroid/OSS app developers; I see it a lot in OSS apps, like Home Assistant.
