Apple

A friend of mine runs his automations off Alexa and based on the headaches it's caused while we are at his house I'll avoid an Alexa ecosystem too, on top of the privacy concerns. We are still a few years off from needing to figure it out, but right now our next doorbell and security system would be through Simplisafe and our Hue lighting system will continue being used. Any additional cameras I'll figure out later, but they must be HomeKit compatible. The LevelLock+ Apple partners with also looks promising.
