Configure an external sensor, it integrates into owfs nicely. All you
need is a small script requesting the temperature from that device, for
example with curl or wget, then output the value to stdout.
An alternative to this is to send the values from the ESP8266 using MQTT and pick them up from an MQTT broker for the higher levels of your application. This may be simpler than connecting in to owserver. Using MQTT opens up a vast array of other stuff that you can easily integrate using something like node-red for the UI. It all depends what you want to do of course.
