I have a Uniquiti G4 Doorbell Pro and a standard mechanical bell (I’m in Europe so it’s a Honeywell chime and the transformer came with the doorbell)
Integration with HA is good, but it does need some sort of Ubiquiti NVR at the very least to operate. I have a Dream Router as my main router so that functions as both. If you aren’t already using Ubiquiti gear this can get expensive quickly.
But the equipment is (in my experience, I know others have variable opinions, especially with software updates) very positive.
Well yeah, it has inferior potassium.
