The main document in the design of the bus is the tutorial from 1-Wire developer TUTORIAL 148: Guidelines for Reliable Long Line 1-Wire Networks. The main thesis are:

• The bus length can be 200 meters when connecting one sensor
• If you are going to connect several sensors, be sure to connect them to 5V power supply (do not use a two-wire connection scheme)
• If you are laying a bus for a few meters, or short, but in conditions of high interference (for example, in the shield) - use a twisted pair, for example, Cat 5, preferably shielded
• The number of sensors that can be connected to a single master (for example, a Wiren Board controller) depends on both the bus length and the bus topology
• Strip line of one tyre is better than strip star. When laying the line with a star, reliable operation is not guaranteed
