The 1-Wire bus system is similar to I2C. In a simple way different sensors can be connected to a normal 3-wire cable (ground, data, and +5 V). For connection to a PC, a USB adapter (DS9490R) or serial interface (DS9097U-S09) are available.
Currently, the following 1-Wire components are supported:
Requirement for the operation of IP Symcon is the current 1-Wire driver (TMEX) which is to be obtained on the following MAXIM page: http://www.maxim-ic.com/products/ibutton/software/tmex/index.cfm
The proper function of the bus and the connected components should be checked with the "OneWireViewer": http://www.maxim-ic.com/products/ibutton/software/1wire/OneWireViewer.cfm
IP Symcon does not support the parasitic mode.
A +5 V power supply is essential!
For further instructions please refer to the instruction manual and the manufacturer's product description.
If you use multiple adapters these can be selected under "Parent instance". How to create a new parent instance, you can find [here] [instances].
Devices should be displayed in the search dialog immediately or after a short delay. After selecting a device, the configuration must be taken before the extended configuration will be visible.
Unfortunately, the connected components on the 1-Wire bus do not send their values automatically - they must be requested. How often this should happen, that you can specify in __ Timer__:
Each query cost time and occupies the bus. Therefore, you should use the "timer" sparingly. In practice e.g. an interrogation cycle of 60 seconds to read a room temperature, is more than sufficient. Smaller values of less than one second can not be set.
Furthermore, it should be noted that the more devices are connected to an adapter, the bus utilization increases. In our model house 30 devices are running on an adapter with no problems. We recommend for larger installations to use a separate power supply and multiple adapters.
