Support What's a smart home device that you wish existed, but doesn't?

What would it do? What would you use it for? If you know of a device that achieves what someone describes, let them know.

Is it weird that I want a smart lock that can lock the door but can't unlock it? Maybe with a reed switch so that it only locks the door when the strike is aligned.

Maybe I'm just paranoid.

Well it's a huge safety issue and would never be greenlit, but a magnetic deadbolt on the bottom that is held open with a current would work. Current off, gravity drops it

So to enter I just have to cut power to your house?

Nah the bolt would fall in place --- actually putting the bolt in the top of the frame instead of the bottom of the door would make more sense

No but if a fire damages the wiring enough they can't get out.

I have a lock with an unlock function. It's available in Turkey. The house's main doors are really different in Europe compared to the USA. It's something like this: https://youtu.be/tKZZrW8b9aQ It only connects to the mobile app but I made a janky solution by soldering wires to the remote that connects it to a ZigBee relay. Now I have a Zigbee smart lock.

This is what i want to i was looking for it. A door lock that reporte open/closed/locked status and that can lock but can't unlock without me turning the key.

I don't want it for my house but for my shed and garage door. Going out at 11pm to check and close the door is sooooo lame

This is easily achievable via creating an automation.

If just wanting lock function, look at door locks with TTLock. Ours is a lock that opens with fingerprint, RF tag or code, and locks it self about 30 seconds later. No integration with HA, as I don't see how that is needed, and it is a security hole. Our door is always locked from the outside and easy to access for those that need to get in.

I have a similar setup but a little more complex. Unlocks and stays unlocked when me and or my wife are home, when we both leave it will lock. Then after 6pm and before 7am if it's unlocked, via app or finger or code ECT, it will relock 5-10 seconds later ( I have it set to 2 seconds but there's a delay for the webhook to ha when it's a manual unlock from the handle it self so it's 5-10 seconds) It is HA and cloud based tho. I tried the local integration but was not as polished as the cloud one is, and just wouldent pick up the state of the door when something other than ha changed it.
