    Wow!!! The Siren 3 Pro looks like an amazingly powerful system. In fact, there’s so much to crow about in the press release that they didn’t even mention the advanced cellular features. But the online tech specs tell us this: “External Antenna, 4G/5G CAT-M1, with fall back to NB-IoT and EGPRS.”

    And from what I understand about cellular evolution, that means the Pro should work well in current problem areas like my home harbor of Camden, and keep working well in many places where older cell tech is on its way out.

    I have had the old style Siren for over a year. Works great, and has already paid for itself when it alerted me to a battery charger failure.
    But despite their claims, their wireless temperature probe does not work inside a fridge. Perhaps there is too much metal, or the cold temperature has negatively affected the battery. The only way we could get a temp reading was to place the included wire temp probe inside the fridge, with the unit itself on the outside. But then the wire caused a gap in the door seal.

      Hi Richard, The original Siren wireless temperature sensor worked fine inside my boat’s refrigerator for about six months (until I got back to Camden and the MTC’s older cell service didn’t work). My fridge is lined in heavy gauge stainless except the opening top that’s made of fiberglass (plus lots of insulation and a Corian cap). Also, the MTC main unit was only about five feet away and above the frig.

      But while that worked OK, I don’t think a refrigerators is a good spot for a wireless sensor. Years ago, I drilled a small hole in the side of mine to wire a Maretron temp probe, and it’s always worked.

    I like the idea of drilling a small hole in the side of the fridge, but the temp probe has a large ring terminal on the end, that would require a 5/8 or perhaps a 3/4 inch hole. I would rather not drill a hole that big in my fridge. So I sent a message to Siren asking if the probe would still work if I removed the ring terminal, and this was the reply:

    “Thanks a lot for reaching out. I am not sure we are qualified to answer your question. Do you have any boat equipped with a Sailsense solution?

    Best regards,

    Siren Marine tech support contacted me today. They advised that the ring terminal is required for proper operation of the probe, but that the terminal could be removed to insert the wire thru a small hole, and then reattached. So that is what I will do. This will void the warranty, but should be a simple solution.

    Hurricane Isaias passed close to our boat, but because Siren told me that the electricity never went off, I knew that there was little or no damage to the marina, or the boats. That alone was worth the price of admission. Thank you Siren.
