Hello MobileTen, Thank you very much for the comments, we have talked with the members of the project and what we want is to avoid the dependency on internet connection to be able to receive push notification on the devices, that is why we want to avoid the use of firebase or any other service in the cloud, that would require us to have an internet connection to be able to receive notifications since they will be for internal use in the company's devices. I understand that with uniqush it will be completely internal and the push notifications will be at the lan network level without the need for internet. I will review the uniqush information to review its installation and I will tell you how it goes. If you have any other suggestion, it will be welcome. Again thank you very much
