I bought this board https://www.sparkfun.com/products/20594 SparkFun DataLogger IoT with a SF TMP117 temp sensor plugged in the board. I am using the adafruit IO mqtt service. After configuring the parms for the mqtt service, wifi and the logging interval everything seems to start and connect ok:

I called the mqtt topic:
Settings for: /SparkFun DataLogger IoT/Settings/MQTT Client/MQTT Topic
Edit the value of MQTT Topic - data type
When complete, press to accept, to discard
MQTT Topic = zzzzzzzz/feeds/datalogger.tmp117
I disabled the outputs for the 3 fields of the max17048 device in /SparkFun DataLogger IoT/Devices Settings/MAX17048
Settings for: /SparkFun DataLogger IoT/Devices Settings/MAX17048
Outputs:
1) Voltage (V) - Battery voltage (Volts)
2) State Of Charge (%) - Battery state of charge (%)
3) Change Rate (%/hr) - Battery charge change rate (%/hr)
When I open the web console of adafruit IO I am seeing updates once a minute but in the ‘value’ of the tmp117 feed I see this as the value:
{“TMP117”:{“Temperature (C)”:27.96875},“MAX17048”:{}}
I just want to see the data value for “Temperature (C)” of 27.96875 not the entire string (Json format ?)
Is there a config setting for that somewhere ?
thanks
