hoary haven
I have a device that's basically become abandonware from the manufacturer but has an undocumented REST endpoint that I presume is meant for the no longer developed app. However, trying to ingest the raw bytes from a GET has been a challenge.
Here's what I've put in my configuration.yaml:
- platform: rest
resource: http://192.168.0.48:3333
value_template: "{{ value_json }}"
logger:
default: info
logs:
homeassistant.components.rest: debug```
Now, when I try to hit this GET endpoint using Postman, it throws an error saying ``Parse Error: The server returned a malformed response``
However, using Wireshark I see the TCP packet is not malformed, and the payload is a basic hex string: ``00c300c8100000661000007110001000``
This string does correspond with actual values, as figured out by this Reddit user: https://www.reddit.com/r/homeassistant/comments/qm7s7i/grill_monitoring_specifically_the_chargriller_980/
In HA, though, it shows that it is polling the endpoint for data but never prints out what data it found/got, so I'm wondering if I can change the value_template property but I don't know what I would need to change it to.
FWIW, that Reddit user jumped from the device -> Node-RED TCP node -> Node-RED MQTT node -> HA. I don't want to set up a Node-RED instance just for this one device, so I'm trying to get HA to just pull in the data directly using REST.
For future surfaceability, this device is the Char-Griller Gravity 980.
