I am trying to connect these two sensors so that I can read them in domotic but unfortunately it does not work as long as I show the temperature of all sensors in the terminal, but in domoticz not anymore. Can anyone help me.

I doubt it's related to the MySensors communication. Are you using a Dallas temp sensor? Could you check that the is actually connected to the dallas sensor by using isConnected().
When googling your problem I found a few hits on -196.6 which is the error code (DEVICE_DISCONNECTED) converted to Fahrenheit.
Start debug mode (Config.h) to see what the sensor actually sends.
