4 channels unit and 1wire port - philippe - 10-22-2021

Hi,

I see that the 4 channels unit has only one 1wire port.

Can you connect several 1wire chips on the same port ( the 1 wire standard protocol)?

Then can you collect with MQTT the temperature(s) from this 1 wire port?

Thank you

if you can write arduino code, you can read 1-wire device for MQTT feedback. Yes , 1-wire port support use by multi sensor, such as multi DS18B20. just according to your arduino code.
