I have an apartment available in AirBnb and I would like to have a solution to open the building door remotely or automatically. I want to do this without changing anything in the building so my only option is to play with my old doorbell system (Contera Starbell 1000).
I already found https://www.nello.io that does what I want: detect someone ringing the doorbell so I can open it remotely. It has the bonus of being able to create rules like “if someone rings between 10pm and 11pm open automatically”.
But I wanted to have SmartThings solution because it is more versatile and after buying the hub I can easily add other sensors to the apartment.
I’m a programmer but I’m not good at electronics so please be patient. From what I read so far, I need a relay to trigger the opening remotely and something else to detect the doorbell being ringed.
I’m the process of finding how the doorbell is powered because it seems that will influence the relay I buy.
So my questions are:
what do I need to buy for this? A single relay? What are the keywords I’m missing to search for them?
If you can suggest specific models or types of hardware it would help a lot.
I want to do a step by step of this afterwards
thanks in advance
