LoRa remote water tank level and pump controller - Client

First the problem: I must refill a 1,5Km far water tank, so I need two devices:

a server that manages a pump: if the remote tank isn't full the server start the pump with a relay and when the tank is full, stop the pump.
- Start-stop pump;
- Manage the remote message;
- Prevent dangerous action if the remote device is no more active;
- Monitor to select an operation mode and status.
A client that is in a remote position (tank position) checks the water level and warns the Server if It�s all ok or the tank is full.
- Check the max and min level;
- Warn Server about status;
- Battery and solar-powered;
- Sleep mode if no more need.

Here is a simple demo video.
