Get JSON data from entity in Node Red

Third party integrations Node-RED
1

Hi, I was wondering if it is possible to get JSON data from an entity state in Node-RED. Someone who can explain to me how this works?

The intention is that when an update is available (sensor = on) I will receive the release notes link and version number in a pushover JSON message.

In short, how do I get this data in a JSON message to pushover?

I know this can be done in automations but i want it in Node-RED.

You can construct a data payload in a template node from your incoming message, convert the string into an object using the json node and feed that into your service call.

Template Node:

{"data":{"message":"{{data.event.new_state.attributes.newest_version}}"}}

You can also connect directly with pushover from Node-Red. You don’t have to tie Pushover to HA.

Thank you! it works now.
