I have been looking at some of the Ring / Yale alarm systems but I already have a lot door / motion sensors and I don’t really want to double up on sensors and don’t really fancy forking out that much…
Is there any decent hardware out there that I can plug in to my infrastructure or possibly use their sensors in HA to trigger automations? (I currently have Zigbee motion / door sensors I am not against replacing these if I can use the new ones as standalone sensors too)
Looking for a system that has a physical input panel and an external siren, can’t be simply unplugged (some sirens I have looked at seem like you can simply pull the power from them…) and not cloud based.
Does such hardware exist?
