Can't log on to home assistant after config update

Configuration
1

I am new to this and trying to follow Bruh $15 DIY multi sensor to get me started

All was going well programmed up a Pi with all in one installer logs in fine. Added MQTT broker and programed nodemcu All this seems to be working

My problem is when updating the config file as detailed in the video.

The detail of the config file has a Sensor: section and when I add this to the config.yaml I can no longer access my home assistant remove it and all is ok.

Can someone look at my config below and tell me how stupid I am and that it obvious whats wrong. Even better if you can tell me what is wrong.

Hope someone can help.

Please check how to format your post to mark the config as sourcecode and then edit your post. It’s hard to help spot errors otherwise.

Sorry should have paid more attention to the welcome post.

Original post edited.

Hope this is better.

I think you need " " around the value_template
value_template: “{{ value_json.temperature | round(1) }}”

Thanks for the quick responce but this change has not fixed the problem.

What does the log say?

This is the log but does not have anything dated today.

You have a duplicate key in your configuration.
Should be:

sensor:
  - platform: yr

  - platform: mqtt
    state_topic: "bruh/sensornode1"
    name: "SN1 Humidity"
    unit_of_measurement: "%"

  ...

Thanks for the support on this but I have solved the issue.

It seems that there was some issue with the copy and paste from the example.

After trying to narrow down the bit that caused the issue I got bits that would work and then not work.

Once I retyped the config sensor section instead of copy and paste it worked fine.

Can you elaborate on exactly what you changed to help others (like me!) who arrive here searching for a solution to the identical problem?

Thanks!
