Hi- I just bought Netatmo and I want to use it with the bell I already installed. The model I have is an 8v Chacon 84199. The problem I have is that while Netatmo works perfectly with Home, it won't ring. After going back and forth with Netatmo technical support, it was established that my problem is that our front gate (where the bell is) is 50 meters from the bell and, depending on the type of technology, this is a race too long for the 8v signal to be stable enough to ring the bell. (The bell is not actually 50 meters away, but the wire cable is other than straight and runs about 50 meters). Of course, there is nothing in the sales literature or Netatmo technology to suggest that thread length could be an issue. Also, the bell works fine without Netatmo, so I don't understand what's going on in the circuit with Netatmo causing this problem. He suggested that a 24v or 230v bell would work. I can't use 230V because the wiring is not rated for such a high voltage. So I wonder if someone with an electric background can explain to me 1) why an 8v signal that goes 50 meters would be a problem and 2) if in fact a 24v signal should solve the problem. I see that most wire bells use a 16 volt transformer. Would 16 volts be enough? Thanks for any help!
