Hello together, the following situation: A somewhat remote hall should be monitored with an alarm system, which transmits an alarm to a mobile phone app (so that you can also get the alarm). The same applies also to the smoke detectors (alarm via a mobile phone app). Perhaps there is also a system that can do both. In the conversation was a Luxone system for building automation (but is almost a bit overkill). Maybe someone has done this before and has a tip for me. PS. Internet. is probably made by means of a Fritzbox LTE (but shouldn’t matter). Thank you very much. Greetings Metalhead
