Completely agree with you! The Aeotec app from Athom seems to be abandoned. Never got new devices as the new LED bulb or tristate sensor anymore, sensor 7 did got added but does not work.
Oh, forgot to mention the TERRIBLE Bosch-Siemens Home Connect app that simply loses connectivity over and over again without reason and never seems to get fixed.
Chromecast issues where you need to add all of your chromecast devices again after every update. NetAtmo app that does not trigger motion alerts correctly…
I thought Athom created/supported apps would be a lot better, but the community supported apps seem a lot more powerfull. I never had any issues with Heimdall, better logic, etc.
