Starting a DIY automated pet door. Have a 1st gen ST hub, and have just a few devices on it - a lightbulb, a Schlage lock, and a Chamberlain garage door. Those are all prebuilt systems, this would be first DIY.
I already have an in-wall flap dog door, and it has a metal sliding cover on the inside. We have been using this with just he metal door pinned up and the dog can go in and out to his heart’s content. However, sometimes at 4 am he wants to go out and tell the deer or fox to get off his lawn.
If we close the metal slider, then that means in the morning I have to get up and go downstairs to open it so he can go out.
Additionally, winter is coming, and I think when it gets cold that flap is going to be leakier than we would like.
I think that this will be relatively straightforward, mechanically. I got a linear actuator and inbound is a monoprice curtain controller (I have found custom device code that will allow that to work with ST). So that is the open and close control, and all by itself would be easy enough to just open and close on a schedule.
HOWEVER - I started thinking through some scenarios. Suppose I have it set to close at 10 pm, the dog goes out at 9:59 and comes back to find it closed. Then he can’t get in on his own. A motion sensor outside would do the trick, but a raccoon could also trigger that, so I want it to be RFID or something like that. And, I would also want to have the RFID on the inside so it wouldn’t stay open all the time, only when the dog came over to open it.
I am thinking, then, I need an inside RFID sensor that can only open the door within certain hours, and an outside RFID sensor that will open the door anytime.
I have seen some RFID implementations for ST and it looks like arduino is the way to go there.
So, any thoughts or direction on this? Have searched the community and googled this but haven’t found anything directly like this.
