Seems that this escalated a bit and i am sorry for that. All i wanted was to explain the statement @teachingbirds said : “Paulus have opened up for the existing android apps to become official, but apparently that doesn’t seem to be something they want” which is not actually true and in fact i offered to make Ariela open source and fix the things mentioned by @balloob.
Now, regarding Ariela and the new official app which is in developing, there is no harm if both of them could coexist and i don’t see why we cannot discuss ideas or even help coding.
Indeed, Ariela tend to be more native in displaying entities, cards etc, meaning that custom lovelace cards will not be supported without extra work. But knowing this , a Web UI mode was also added for the users who do not want to use native. Same for MQTT, device tracker and most of Ariela functions, the functions exists in the app, but at the end users will have to choose if they will enable them or not.
At the end all i can say is that if anyone want my help or have any questions regarding Android & Home Assistant, please do not hesitate to ask, this being my way of helping this wonderful community.
