Home Assistant is open source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts. Perfect to run on a Raspberry Pi or a local server. Available for free at home-assistant.io
Why a keypad? I use a GROW R503 fingerprint reader to arm and disarm. Works very well with HA on ESP board. Cheap and effective, for multiple users and if you want you can save all your fingers.
