 ===== Hardware =====
 Using a ESP32 with QMC5883L compass module. TBD
 ===== Accuracy =====
-TBD
+Quite accurate, each interval (max to min to max) from the water meter appears to be 32.5ml, this was confirmed over the course of a few days and about 1.6 m³ of water (about 49 thousand intervals).
+{{ :esphome:watermeter:watermetermagneticfield.png?800|}}
 ===== ESPhome yaml =====
-TBD
+This is still a work in progress, and will need some customization for your specific installation (such as defining which magnetic axis to monitor and thresholds).
