Couple of times my basement had suffered from ... well... sewage overflow due to different breaks in sewage pump. That's nasty and this must be terminated.
In Github there's full description of the project, including:
- Hardware design;
- ESP8266 code;
- Node-RED code;
- Installation instructions.
The controller monitors the water level and the pump work. If something goes wrong (water too high, pump is broken) it takes some actions (when applicable) and reports to MQTT broker.
Thoughts for improvement are welcome.
Hope this will save someone else the serious renovation...
