I've defined the digital inputs and switches as in the example and also added a DS18B20 temp sensor to the I2C. But as soon as I add in yaml the Dallas configuration, the update_interval toggles the switches on and off at the interval set in the update_interval.
I saw that the I2C port is the same as the Dallas sensor but I don't know how I can connect them in a different way.

DS18B20 can't use I2C bus pin. if you want to use DS18B20, try to use other free GPIO, such as there is a serial port extender on PCB (white 4pin socket).

Thank you for the info, it was a confirmation of what I have to do.
So, I've used RX from the extended serial pin GPIO14.
Also I've added a 4.7K resistor between data and VCC+ (3.3V) of the temp sensor. It's not working without the resistor, that's why it wasn't working yesterday.

Thank you!

RXD:GPIO14
TXD:GPIO33
you can try to use by GPIO14 or GPIO33, if GPIO14 not work, you can try GPIO33.
