Smart Deadbolt - add manual open switch

[EDL-Kevin]

Looking for help with smart deadbolt opener. willing to pay for services.
Opener design to be controlled via Blu-tooth and/or wireless.
Need to add switch/s open / close manually to interface with building access control. prefer dry contacts.

Difficult without detailed information. I assume the wires going to the white plug/socket are to a motor in the plastic molding and that motor moves the deadbolt. That would imply the polarity has to be reversed between opening and locking directions. If the supply has to be reversible and the present functions retained, the circuitry might be quite complicated. It might be easier to mimic the WiFi/Blu-tooth signal from a real controller and link that to the building access control. Is there any information on the WiFi protocol it uses and on how the building access control works?

The comm module is Bluetooth... Spectrum Brands 450-00022 link https://www.google.com/url?sa=t&sou...sQFnoECBQQAQ&usg=AOvVaw1a_ioPj3NCwDPxnbrM83B8
I can mail you both PCB if you think you can help... have 10 units/doors to modify if possible. Thx Kevin

I'm not sure which country you are in so mailing the PCB might be a problem. I'm in Wales on the west coast of the UK.

However, the PCB itself will be almost impossible to modify, what I'm suggesting is to fake the Blu-tooth signal from a new device located nearby. The lock wouldn't know whether it was an 'official' device operating it or the new one. Making a Blu-tooth transmitter is fairly trivial and I assume a power source for it would be available nearby. The problem would be finding out what the original device sent to the lock to operate it so the new device can mimic it. You also want it to be connected to an existing building access system so I would need to know what that system produced that could be made to trigger the new device. Incidentally, a module with WiFi and Blu-tooth is very cheap these days probably around $5US.
