Very easy to set up and convenient to use. I like being able to see the temperature and humidity directly on my Victron screen
I use a couple of these to monitor temp & humidity in different places in my camper. I use the silicone holder to mount them to walls. They work as intended, but the best feature is that they easily integrate into my Victron system.
I haven’t used the new ones I got from Blue Marine yet but I have a couple of other Ruuvi sensors I used in my refrigerator that keep me informed what temperatures are present in both the refrigerator and freezer. I will be using the new ones in my trailer to let me know what temperature offset I need to use for my heating and cooling settings. The remote temperature sensor for the system is located on a warm wall that gives erroneous readings.
I wanted to measure the heat of the inside of my truck cab while away. I have a victron system in the back with a cerbo gx. I placed this puck into the truck cab and connected via bluetooth to the cerbo. It's all working perfectly. I have realtime and historical tracking.
Have one in the engine room and one in the cabin. Both devices hooked to my cerbo gx seamlessly
