Raspberry Pi3 + XBee + XBMQ + MQTT + Node-Red IoT

This instructable is comprised with the notes I took during the implementation of the project. What I have working at home now is a system managed by a Raspberry Pi that is controlling the well Water Pump and receives the signal from a cheap Water Level Sensor on the Water deposit. Just so you know, the Water Deposit and the Water Pump are quite far away from each other, I could not use cheap wi-fi receivers as the signal is lost. So, my old XBee’s that were gathering dust came in very handy for the project. Also, the Water Pump takes a long, long time to fill the deposit, so we had some incidents where people activated the pump and forgetting about it.”
