Can gpio05 and gpio14 work at the same time?

I tried on one_wire to define both but accepts one OR the other.

I want dht11 on one pin and DS18b20 on the other.

[admin]

Do you use KCS firmware or ESPHome?

[xarouli5]

Esp home. 

We need two sensors:

(DS18b20) on Tp1 and dht on tp2.

Can both be used at the same time?

How many on each channel using both channels?

[admin]

sure, you can use two gpio at the same time.
if you using ESPHome, also support one gpio with multi DS18B20 sensors.

[xarouli5]

One gpio with many DS18b20 
Also the other gpio with many Dht11?

[admin]

yes, that according to ESPHome, one gpio can work with multi ds18b20 sensors. But one gpio ONLY work with one DHT11 sensor.

[xarouli5]

I have a DS18b20 on GPIO14 and working. Trying to use a Dht11 on GPIO05.

The code I use (try) is:


 #

one_wire:
- platform: gpio
  pin: GPIO14
  id: one_wire1
- platform: gpio
  pin: GPIO05
  id: one_wire2

Sensor 
 - platform: dallas_temp
   name: #AIO DS18B20 #1"
   update_interval: 10s
   one_wire_id: one_wire1

 - platform: dht
    model: DHT11
    one_wire_id: one_wire2
    temperature:
      name: "Temperature2"
    humidity:
      name: "Humidity2"
    update_interval: 10s

#



The error I get is:

INFO ESPHome 2024.12.4

What am I doing wrong? I am using 3.3v for Dht11. Tried 2 different sensors, both same error.

you can update your esphome to 2025.3
now the one wire sensor yaml format have changed, you can check with esphome webpage.

[xarouli5]

For any other looking the same:

The problem was not the version of ESPHome, though I updated had the same error as before. 

The code working:

#

one_wire:
- platform: gpio
  pin: GPIO14
  id: one_wire1
- platform: gpio
  pin: GPIO05
  id: one_wire2
#no need to define one_wire2 for a reason I don't understand but it works like this. #

Sensor
- platform: dallas_temp
  name: #AIO DS18B20 #1"
  update_interval: 10s
  one_wire_id: one_wire1

- platform: dht
    pin: GPIO05 
    temperature:
      name: "Temperature DHT11"
    humidity:
      name: "Humidity DHT11"
    update_interval: 60s
