| I'd like to create an automation at home in which when we come into the house and you come home the air conditioning turns on. | |
| So we have a climate device in the living room and the summer we want it on cold so all that part is good. | |
| We have a front door sensor for security. | |
| What I realized is that there's no way from that to distinguish a person leaving from a person coming in. | |
| This little world is gonna look like the same event from the sensor. | |
| So what do you think of this idea? | |
| If we had something like a smart lock it would be pretty easy. | |
| When the door is unlocked, coming in, you turn on the AC. | |
| But pending that, can you think of any sensor that we could have or a way to leverage our existing sensors that would allow this to work? |
