What can we do with this card?

Hi
I bought it and expected miracles I dont see coming.
To be honest, I bought it before Christmas and couldnt land where I expected:
-a new alarm card with a web interface to configure, a capability to wire my existant sensors and to add some wireless, the capability to connect my wired sirene and keyboard.
I wonder whether I realised correctly that this alarm card (panel pro v1.9) is “only” capable of reacting to signals on the input by reactions on outputs, and to switch between armed or not armed status, maybe using a code. Everything else is outside: phone to someone, …
As far as I was I could arm it using Alarmo, but I never found how to block an input.
Well, I am very sceptical and wondering whether I wasted my money.
I am really open to learn the possibilities and accept I’ve mistaken. Then it would only be a matter of finding the teasers and the info.
To start, it is not clear about the firmwares customisations (defining the zones, etc) whether it is a step toward HomeAssistant or to avoid in case of this. Then the followup.
For now I am first blocked with I cannot reset the firmware any longer. The flashing refuses telling :
Unexpected error: ESP Chip Auto-Detection failed: Failed to connect to Espressif device: No serial data received.
What does it mean? Is the card dead?
Thanks for support.
