aged beginner here, working my way through my Home Assistant installation. Have a few basic things working (light switches, and automations) and want to tackle an alarm system using Shelly devices. I have some basic questions to which I could not readily find answers…
Q1 - Do I need to install the Shelly integration in order to use any Shelly device ? I have a couple of Shelly buttons I want to use to run some scenes, and also hope to use Shelly motion sensors and door-window sensors to set up al alarm.
Q2 - What is the best alarm set-up using Shelly sensors ? Alarmo ? or the HA Manual Alarm Control Panel ? something else ?
Any pointers on this anyone may have for a retired fellow new to HA woudl be most welcome !
