MicroPython board with wireless connection and battery, with 1 year battery life

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:

I don't understand what the difference is between

ESP32 DevKit-Lipo

ESP32 DevKit-Lipo-EA

and I would like to use this battery:

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)
