Currently, I have a very large (and growing) zwave and zigbee network managed by smartthings that run several custom smartapps (some I wrote with pain and others wrote) without other hubs to run my house . And I had it with Samsung. You want to finally throw my SmartThings hub in the trash. I would like to incorporate HomeKit into my smart home to use Siri, phone location and the new airtag as presence sensors (if they can be used as such to control automation at the entrance and exit of the house) and use the HomeKit application for manual Control. The main automations of my house I want to get down from the cloud and run locally. I was looking at the homebridge but it seems that from the homebridge you can't see or control the HomeKit devices (maybe by making a virtual switch in the homebridge, then the HomeKit device to control the virtual switch?) Or connect the zwave or zigbee devices directly to the homebridge? But from what I can tell, it looks like the home assistant may. Correct? But is the home assistant harder to use? Can any of the 3 be set up to send alerts to my phone if the battery is low or a water sensor detects water, for example? I think the main question is whether I should start with the homebridge for its ease of use to find out what HomeKit is capable of doing, then get a second rpi to run the home assistant when I am ready to start wiping devices from SmartThings and bring over complex smartapps? Or is there something better to use. Can both Homebridge and Home Assistant connect to HomeKit and SmartThings at the same time during the transition without blocking anything?
