Template sensor config for JSON

[metbril (Robert 🇳🇱🇪🇺)]

I’m afraid you might need a custom component

[SOLVED] Parsing a json value from an existing entity in a template sensor

Here’s what I’m trying to do. I have a REST sensor to get status from my rooted TV: sensor: - platform: rest resource: !secret samygo_tv_living_channelinfo method: GET name: TV Living Channel Info scan_interval: '00:05' The data returned by this sensor is in JSON format and has several fields (extracted from the entitiy view for sensor.tv_living_channel_info): {"source":"TV (0)","pvr_status":"NONE","powerstate":"Normal","tv_mode":"Cable (1)","volume":"7","channel_number":"45…

Truncate sensor.rest to 255 characters. Parse JSON and store in attributes.
