Product Details
✓No Wi-Fi. Cellular on Verizon. Works when the cottage has no broadband and when the router is dead. Preinstalled Verizon SIM this is not a Wi-Fi thermometer.
✓Phone-call, text, and email alerts for freeze, humidity, power loss, and water leaks. When the heat dies, pipes are at risk, the power goes out, or a leak starts. 24/7 — you do not have to check an app.
✓Two SPuck water-leak sensors in the box. Place at the sump, washer, water heater, or basement. This is the Home Watch kit — monitor plus two leak sensors, not the monitor-only listing.
✓48-hour backup battery. Keeps reporting through an outage so you hear about the freeze or the leak, not after the thaw.
✓Subscription required — from $8.25/month when paid annually. Plug in, place the SPucks, activate. Monthly and seasonal plans cost more. Verizon coverage only.
✓What's in the Box: MarCELL M2 cellular monitor, two Water Sensor SPucks, 5V power supply, preinstalled Verizon SIM.
