Dallas Temp Sensor

[telewizard13]

   
I have been trying to install a Dallas temperature probe on the AIO board and have been unsuccessful. I used an Arduino Uno and a sketch to retrieve the address of the 10 probe(s) I purchased and as I got the address I marked a number on the probes to keep them identified. I tried two different probes, red lead to +3.5V, Black to GND and tried both IO pins 4 & 5 to no avail. I get an error in the logs that I have no idea what to do with.

take a photo , how you wire your DS18B20 with AIO board.

I found the error The DS18b20 address your AIO config program discovered was not the same as the address reported by the discovery sketch that was used on my arduino.

[admin]

sure, every DS18B20 have different address, you can't use my address. you need discover find your own sensor's address, then replace in yaml file.

I read somewhere that the AIO only supports one Dallas temp sensor. What would you recommend for adding additional wired temperature sensors to monitor other locations in my home? Otherwise, I might just use Zwave sensors,
Thanks!

[admin]

you can use multi ds18b20 with one GPIO, just connect wire together. see this demo case: https://www.kincony.com/forum/showthread.php?tid=5886

Since I already have the AIO board, would the YAML file you referenced for multiple sensors be entered as a separate file in the system config, or would the AIO Yaml be edited somehow.  Sorry for the dumb questions, but I'm new the this.

[admin]

only edit one yaml file, for example:
dallas:
- pin: GPIOXX

sensor:
- platform: dallas
address: 0xA40000031F055028
name: "Temperature #1"
- platform: dallas
address: 0xDD0000031EFB0428
name: "Temperature #2"

here is details from ESPHome webpage: https://esphome.io/components/sensor/dallas.html

Got it! Thank you very much!

I'm attempting to get working dallas temperature sensors across 2x bus. I can't seem to work out the YAML can you provide some help please?

one_wire:
- platform: gpio
