Lost Connection every 20sec

fylo · February 4, 2020, 12:00am

Hello,
i have an simple setup: ESP 8266 with several DS18B20 sensors. I use ESPHome and the API connection to Home Assistant.

Everything works well:

But every 20 sec the data of all sensors is set to yellow:

And after a minimal amount of time the display swith to normal.

The Update intervall of the Dallas Component is set to 15 sec.

What can i do to change this behavior?

This is my config:

esphome:
  name: heizung
  platform: ESP8266
  board: nodemcu

wifi:
  ssid: "SSID"
  password: "passwd"

logger:

I have re-compiled (with no changes but some libs where updated) the firmware and now the problem is gone.

fylo · February 9, 2020, 11:50am

The problem is still alive. As long as i run “esphome.exe heizung.yaml logs” over wifi from my desktop everything is ok. But when i stop the logs the problem returns.

Hi, i have exactly the same issui, did you fix it with your ds18b20?

Do you have the Sensors connected to +3.3V or +5V?
and what value of Resistor do you connected between DATA and VCC? 4.7KOhm?

I have connected 4.7KOhm between 3.3V and DATA, the sensors are also connected to 3.3V.
