"Entity not found" error after POWER goes OFF and ON

nehulagr · April 1, 2019, 7:33pm

I am facing a challenge with Hassbian installed on my Raspberry pi 3 B+ . Everytime when a whole system (wifi router & raspberry pi) goes power down or switch turn OFF, and after sometime turn ON, its not able to detect my any MQTT devices which is almost all the devices.

Here i try editing /etc/systemd/system/[email protected] file

[Unit]
Description=Home Assistant for %i
After=network.target mosquitto.service

Even after this it didn’t help. I have my my Mosquitto enabled by default on startup.

If I manually restart my Home Assistant I can see all of my devices back again.

I am not sure where I am making any mistake. Here is how my configuration.yaml looks like:

homeassistant:

  name: Home
  # Location required to calculate the time the sun rises and sets

Any suggestions? Why this is keep happening? I have tried a lot of things but none of them are effective as it should be.

Thank you!

Did you manage to resolve this? I have the same problem.

nehulagr · December 24, 2019, 7:13am

I have to unfortunately install Hassio. Instead of hassbian. Then I got this problem resolved. Also I used the Entity created from PayLoad directly instead of creating it manually. This is helping me to solve this problem easily.

Hi @nehulagr, I am struggling with this problem too, my MQTT sonoff switches do not come back after a server restart. Can you expand on what you meat by:

as all I have done was add the MQTT to the configuration as you showed in the original post.

Rupert_Roos · March 4, 2020, 10:56am

I somehow missed your reply.

What do you mean with “Entity created from PayLoad directly instead of creating it manually”?
