MQTT sensors.yaml

Configuration
1

I have a general MQTT question. The device publishes this:

tele/pow1/TELEMETRY {"Time":"2017-01-01T13:50:17", "Energy":{"Yesterday":"0.234", "Today":"0.016", "Period":5, "Power":53, "Factor":"1.00", "Voltage":214, "Current":"0.247"}}

What is the correct way to define a sensor that displays for instance “Current” ?

Look at the examples here:

I’m not sure about the nested values, but I’d try something like:

value_template: '{{ value_json.energy.current }}'

I understand the value_template, it looks like HA doesn’t get the information from the MQTT broker. See this page: https://github.com/arendst/Sonoff-MQTT-OTA-Arduino/wiki/Sonoff-Pow

What topic should I use in my sensors.yaml ?

I’m not familiar with this sensor, but it ssems there is a “legacy” message format and a “new” one?
So you should get the current by subscribing to tele/pow1/CURRENT using the legacy format.
You’d get the JSON reply with the new format by subscribing to tele/pow1/TELEMETRY.
