DS18B20 wiring for RJ12 / max cable lenght of AM2320

[atosz]

Hello,

I have several question regarding sensors and sensor connections.

1. I would like to connect some DS18B20 to my LanController v3.6 via RJ12 splitter.
   What is the sequence for RJ12?
   
   
2. A question for RJ12 splitter:
   - is it possible to connect more than one AM2320 to LanController via RJ12 splitter?
   
   
   
3. At the moment i am using one AM2320 but i always need to press "I2C sensor detection" (Inputs menu) for displaying the values, after a few mins or sometime a few hours it does not show automatically any more. Is it possible that the sensor is too far from the LanController? The cable lenght is around 8-10m.
   
   
4. There is a menu called "I2C and 1Wire Sensors". Is there any manual how to use this section?
   

Thank you!
