ESP32cam - control remote door - local and from website

Add remote control with a HTML app and JSON/Ajax for signalling on Platformio to a current ESP32cam wifi project. Device works but currently no remote control (so device works but need to press physical buttons to activate device). Code built on Platformio. Project parts: - Esp32cam - MCP23017 GPIO expander >> this works for me - Motor controller (with 12v motor) - Relay to control solenoid lock - Solenoid lock (with limit switch - controls max motor position and indicates solenoid position) - Buttons x2 - Touch sensor - Limit switch to control neutral position of motor - ON/OFF switch - 2 LEDs that indicate power on/off and status of lock - Use C++, HTML and JSON/Ajax to create remote control via wifi for device Part A Local control of device (on same network) - HTML/JSON/Ajax app for local control - Shows webcam (live view) - Take pictures (and able to save/review pictures) - Virtual button 1 - turn on/off webcam - Virtual button 2 - take pictures (and able to save/review pictures) - Virtual button 3 and 4 - open 'door' and close door - Shows status of electronic parts (for debugging) - Relay, B1, B2, TS, Relay, SW1, SW2, in1 and in2 - Send notification when door closed (locally) - with picture Part B Website control of device (on different network and from my website) - use websocket?? or?? - HTML/JSON/Ajax ? - Shows webcam (live view) - Virtual button 1 - turn on/off webcam - Virtual button 2 - take pictures (and able to save/review pictures) - Virtual button 3 and 4 - open 'door' and close door - Shows status of electronic parts (for debugging) - Relay, B1, B2, TS, Relay, SW1, SW2, in1 and in2 - Send notification when door closed (locally) - with picture *** - Here are tutorials for something similar to what I am trying to do: 1) This tutorial is very close to what I need... [login to view URL] - but does not use JSON/Ajax to send signals to the remote controller and not HTML 2) This tutorial shows esp32cam controlling car - [login to view URL] - but I want to use JSON/Ajax to send signals to the remote controller and not HTML - and there would be 3 virtual buttons on controlling 'app' - 1-turn on/off webcam, 2-open door button and 3-close door button - and at bottom of screen - show status of components 3) This tutorial shows using JSON to send signal web controller - [login to view URL] - And I don't want to use Husarnet services - so just controlling the device locally - I think JSON/Ajaox is better way to send information!
