The [QMC5883L](https://esphome.io/components/sensor/qmc5883l.html) is a common and inexpensive option that ESPHome supports. Many posts on the forums of users having luck with this method, such as [this one](https://community.home-assistant.io/t/water-gas-meter-monitoring-via-magnetometer-sine-wave-to-pulse-issue/245904).
