My opinion on the V3 is if the better night vision doesn’t help you, then keep it off. The V3 is so much more sensitive to light that you may find you don’t have a need for it, especially if you have a yard light.
The thing about the new starlight sensors is they see visible light – take someone who is dressed all in black – An IR sensor might see that as someone wearing white, where the visible light starlight sensors might see them in actual black. The actual color they are wearing is a much better description, no?
As far as a Sense bridge on a V2 – I am with you. Awaiting the next iteration. In the meantime, I just replaced my V2 bridge cam with a V3, so I plugged the V2 with the bridge in nearby, but turned the camera section off in the app.
