Tips to improve an alarm system with Homey

I carefully checked the forum and security apps and did not find the solutions you propose.
EUFY, it is not clear if it is possible to control di siren throught the base. I do not see any card available for this command in the app page but maybe there are more available. We need someone already went on this solution to be sure. In any case the base affects too much the cost of a siren.
The Eufy keypad seems to see supported but by the app but look again at the cards, it seem you can only check the battery level and the temperature! Same as the siren for the costs.

FRIENT keypad was my first choice because I prefer Zigbee but seems there is a big problem controlling it by homey. In this post is reported a problem that i think it is fundamental. If it is not possible to disarm the alarm from the keypad why do i have to install a keypad?
Thanks for suggestions and let me know if I’m wrong.
