Long story I got lock out of my office on Friday with no phone,wallet or key. The office door is control exclusively by RF sensor and and capacitive switch.

 

 

 

 

So using some sort Arduino/NodeMCU micro-controller, how could I buy pass the capacitive switch to be controller via the web?

Are you the owner or landlord of the building or otherwise able to make any modifications you like to the control system? Or do you need to be able to kludge something onto it without modifying the underlying system?

 

 

 

And how will a web based system solve the problem you had? If you have left your phone inside, how would you be able to get onto the internet so you could open the door?

 

Much better would be a keypad where you could enter a password to open the door. Also a web based system would be difficult to both make really secure, And allow access from unknown devices and /or IP addresses. Especially against brute force attacks. At least with a keypad, an attacker would have to be on site, instead of anywhere in the world with an internet connection.

I'm a tenant of the office, but what ever I implement will need to have a non-destructive/non-visual alteration. The idea of having a web based door release was I could ask a fellow work college to remotely unlock the door.

 

Security is an obvious factor to think about but I have lots of methods in handling that.
