@Mike-M,

Deadbolts are definitely on the company's radar, but I believe that the focus will first be the doorbells and the features that were announced at CES.

I will make sure to pass the feedback that it is something that we are still receiving request for.

As for the technology:

Wired connections would most likely not be as popular, due to the additional wiring and setup needed. I  would imagine that if something were to release such as this it would require a similar wiring setup to conventional doorbells - something that we are seeing less and less of in new developments.

For Power However, you are correct in saying that Wi-Fi integration will provide a strain on the battery. The inner workings of Wi-Fi require devices to stay awake for a long period of time, and it requires far more power to actually transmit data - this is why you see so many bridges on the market, as you want door locks to have the longest battery life possible.

This is also where some of the low-power technologies, such as Tapo's Sub-Ghz comes into play, as devices can have extremely long battery lives, while also providing quicker response times. I do think that a lot of your recommendations are being taken into account for our doorbells, so it may just be a matter of time.

I will throw this out there, even though i haven't seen any updates about it being released or seeing the light of day anytime soon but: Tapo did tease a Door Lock at CES this Year: https://www.tp-link.com/us/home-networking/cloud-camera/tapo-smart-video-door-lock/

We have a lot of exciting things planned for our Smart Home Brands, so keep an eye out for updates over the next few months.
