Hi, I would like to use my RuuviTag in my freezer but it doesn’t show up on my RPi. I guess the metal case of the freezer is preventing the radio waves from getting out. Does anyone have any suggestions to get around this problem? Is there a way of having some kind of wire aerial that I can lead out of the freezer door?
Generally the signal can get through the insulation. Have you checked the signal with phone right next to the freezer?
I have good experience with the Tag in freezer, All would be about the construction of the freezer. As with all radio transmitters they are not happy to be put inside an Faraday cage
