Im trying to figure out a way i can have entry into my living room locked by nft access. Can i set something up on my phone that will ping too a smart lock? is this already done?

You use the python or JS web3 library to ask the users private key to sign a message you control. Then you "recover" the public key/address from the signed message. Then you ping infura and ask for the balanceOf the nft contact for that public address.

You want to send a command to some server (maybe the AWS API gateway fronting a lambda function), authenticate that you own a particular NFT, and then have the server command the lock open.

Is that right?

Yes how

I'd stick with putting the logic in the lambda function. See these
