IoT Pool Monitor Helps You Keep It Crystal Clear
Having a pool is great, but it also requires significant monitoring and maintenance to keep it crystal clear and clean. The OPNpool controller from Coert Vonk aims to help in this task; integrating neatly into the smart home ecosystem of today.
OPNpool runs on an ESP32, and is capable of monitoring pool controllers, pumps, and chlorinators; as well as working with thermostats and other hardware to control the state of the pool. This allows the system to do useful things like run high-powered pumps when electricity is cheapest; or to find the best timing to run heating circuits. The controller relies on MQTT messaging and can integrate with Home Assistant; for those that prefer to run their own cloud-independent smart home systems.
With WiFi onboard the ESP32, there’s no need for a hardwired LAN connection, and the system can be administered remotely over the web. It’s also capable of talking with other hardware over RS-485 and bringing it under its own control. With OPNpool installed, monitoring pool conditions can be done from the leisure of one’s deck chair with a smartphone, rather than squinting and dark LCDs in equipment cabinets.
