ESP8266 controlled stretch limousine

IoT solution to control the interior of a stretch limousine

Similar projects worth following
Sometimes ago a customer asked us for help with the interior control of his Lincoln stretch limousine. The old solution was not so nice, there was no comfortable solution for the driver to control the lighting in the passenger cabin and he wants a remote control via mobile app in the future. Our Solution fulfills the following requirements:
 
control via touch screens with modern GUI
2nd touch screen for the driver
communication of all components via WiFi
rugged design
simple to extend
 
We've used the ESP8266 - especially the Wemos D1 mini - for our solution. These modules comes with integrated USB  Module (makes programming easy), are supported by a big community, they need no boot time and are very simple and rugged. We've used the Arduino IDE for the programming of the firmware.

Why all this electromechanical relays? There are so many MOSFET based high side switches on the market now, e.g. from Infineon or ST, down to less than 10mOhm on-resistance. They also produce less heat than the relay coils.

These relay boards are part of the original installation. We've tired to use so much existing parts of the old system as possible....
