The board must have a web server and can send/receive HTTP GET commands and write/read the GPIO pin status (we could use ESP32) , using web server and a web page it is possible to turn on/off some GPIO and read some GPIO status. I would like to use the Olimex ESP32 card: [login to view URL] I don't understand what the difference is between ESP32 DevKit-Lipo ESP32 DevKit-Lipo-EA and I would like to use this battery: [login to view URL] If we use a rechargeable battery, the battery life can be 6 months If we use a NOT rechargeable battery, the battery life can be 1 year The customer also wants a version without battery but has wired ethernet with RJ45 connector The board can sleep and send an HTTP GET message to another Web server when a switch closes or opens. The switch could be a door or it could be a window or it could be a water meter for measuring water m3, so the HTTP GET command is about one every hour and the transmission module turns on every hour but the GPIO input reader must always be active If the card is not supplied with MicroPython installed, I also need assistance to install MicroPython inside the board (step by step assistance, for example using Teamviewer)

Ciao, My name is Andrei, i am a Romanian IOT Developer with a lot of experience in IOT projects and automatics . I use ESP32 for a lot of application, i can program them with very low power procedures, let's discourse more about the project . I can work with all types of Microcontroles programming in C , C++ , Mikro C , CCS C , Atmel Studio , Arduino , gcc . Creating Schematics and PCB in Kicad , Eagle , EasyEDA and Proteus (+simulation). i have an workshop full of parts and the infrastructure to build PCB and test the solution end to end using special tools (Spectrum analyzers , oscilloscope , logic analyzers ) Derivable on the project : Wiring diagram for prof of concept . Schematic design MCU code explained every line . As an additional service i can make you a full working prototype and ship to you. Regards, Andrei
