Product Description
Monitoring the temperature of your boat (or RV) can be important to maintaining the health and safety of your vessel. My reasons for such monitoring have included ensuring that the heat is working (and nothing is freezing) inside the boat, that the air conditioning is working (and nothing is cooking) inside the same boat, that the engine room temps are normal underway, and that the conditions are safe for pets. It's not always simple or cheap to get this information remotely, but I've recently come across an inexpensive and simple option that's worked well for two months, the Govee WiFi thermometer and hydrometer.
