ZHA or Zigbee2mqtt
(lemmy.ml)
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
I'm on Z2M, mostly because it supports more devices I'd like to use. If ZHA supports everything you have or might want to get in the future, I don't see a reason to switch.
