PoolMaster

Complete pool management system which automates water maintenance and control.

System continuously monitors various metrics and periodically reports them over MQTT and touchscreen:

• Water and Air Temperature
• Water pressure
• pH (with temperature compensation)
• Orp
• Chlorine level
• pH level
• Water Level

pH and Orp are continuously adjusted thanks to two peristaltic pumps controlled by two PID regulation loops.

• Liquid Chlore
• SWG (Salt Water Chlorine Generator) through external command and control
• Liquid active Oxygen

Tank-levels are estimated based on the running-time and flow-rate of each pump. Additionnally a low level contact can be plugged into the system.

• 3.5'' Nextion TFT touchscreen for local information and control
• MQTT integration with home automation systems (Home Assistant, Jeedom, NodeRed, InfluxDB, Grafana, etc.)
• Long term statistics
• Phone App templates for home automation systems

• Filtration pump automation reduces energy consumption and adapt filtering time slots according to water temperature (70% of swimming pool energy consumption is for filter pump)
• Thanks to its embedded RTC (Real Time Clock) the system keeps track of precise date/time even when powered off (Adjusted automatically via NTP or manually)
• Winter mode reduces filtering at its minimum and ensure freezing protection (perfect for active filtering during winter)
• 2 spare relay outputs for controlling external equipment (heating, lighting, etc.)
