Not just the cable part?** A: No, just the cable. We have plans to make a floating sensor for pools, but until then, you need to put the sensor where it will not be submerged. This is not a fully company-encouraged solution but some customers put these in a tupperware style sealed container, drill a hole for the probe, caulk that up, and leave it to float in the pool or hot tub. It's a little DIY and not the best solution but I wanted to share that with you in case that might be an option for you. Enjoy! Eric with YoSmart **Q: Can this be used to measure temp inside a chest freezer? Will signal get out of the chest freezer?** A: I have this YoLink model inside my chest freezer and refrigerator: Smart Wireless Temperature / Humidity Sensor Wide Range (-22 to 158 degrees) for Freezer Fridge Monitoring Pet Cage/Tank Monitoring Smartphone Alerts, Works with Alexa IFTTT, 2 Pack - Hub Included The model you’re asking about, I have one outside and one in my garage. The model in my freezer and refrigerator works great. If you already have a hub, I don’t see why the model you’re asking about wouldn’t work inside a freezer. **Q: How to replace the two AAA batteries?** A: Remove 4 small rubber "pads" at the corners. Remove 4 small Phillips screws. Remove cover. Replace batteries. Reinstall. **Q: Can I put this inside a water reservoir to detect when the water reaches a certain height?** A: We actually have a Water Level Monitoring Sensor that would be much better for your application. It comes with a water-sensitive probe, and the sensor can also work with standard float switches. It's not available now, but before too long we'll also offer a float switch as an accessory.
