I bring to your attention my version of the reading of water meters.

The basic idea was to always see from the phone:

1. current meter readings

2. when and how much water was spent

3. viewing comfort

The device is based on the ESP-03 board. It has two modes of operation: setup mode and reading mode. In setup mode, ESP is a web server that provides a page with settings. In the mode of taking readings, changes in readings are recorded and transferred to the Internet Of Things - ThingSpeak.

The application for Android phones allows you to:

1. view water consumption by hour, day and month

2. there are 2 widgets
