Sensor not updating when passed data from json object

Hello all,

I’m trying to send data to my home assistant via my ESP8226 module,

I’ve setup a webhook, which works in sending data to my home assistant through an automation, it works fine as I’m able to receive temperatures and it shows up as a notification:

Now I’m trying to update a custom sensor I added to configuration.yaml:

So that every time the webhook is triggered it would update the state of my sensor

But It doesn’t seem to be updating I’ve checked the traces and it is pulling the data fine as its being shown in the notification area, but not updating the card:

I’m new to this and would really appreciate any assistant in getting it working,

Edit: I have updated the entity_id to match so sensor.my_shed_sensor

Cheers

Josh
