Review: Perfect for Monitoring Christmas Tree Water Levels - I bought this to monitor the water level in my Christmas tree stand, and it’s been perfect for that. It alerts me when the water gets low so I can refill it before the tree dries out—no more needles all over the floor. Setup was easy, alerts are reliable, and the LoRa range works great even with the tree not near my router. For a non-traditional use case, it’s worked flawlessly. Simple solution that actually does what it’s supposed to do. Review: Great sensor - Great sensor ## Features - MANY APPLICATIONS!
