Solid once the firmware is updated

Overall it's exactly what I want from a water sensor - The device works with multiple protocols and was easy to configure once I got the firmware updated. Out of the box it was an older version, I think 1.8.9. It kept turning off during provisioning or would power down Wi-Fi while navigating the UI to configure it. Once updated to 2.0 it's been solid in every way imaginable. I love how I have it joined in to Home Assistant from multiple directions - The direct Shelly integration, Matter over Wi-Fi, Zigbee, and even MQTT. The flexibility is fantastic. It'll be an easy five stars once I know they're shipping with newer firmware out of the box.
