Smart lock company ThorBolt has released a new smart door knob for interior doors that features a fingerprint sensor and can be remotely controlled using Apple Home, HomeKit News reports. If you ever wanted to lock up your home office to keep the kids from screwing with your stuff, the GK1 Smart HomeKit Fingerprint Door Knob could be the way to do it. That’s pricier than the many generic smart interior door knobs out there, but it’s not surprising given its smart home compatibility. The ThorBolt GK1 connects via the smart home-focused mesh wireless protocol Thread but lacks Matter support and only works with Apple Home. See ThorBolt GK1 at Amazon
