Remote Temp Sensor

[Midwestfarmer]

I want to use my CDH as a portable heater that sits outside of my little camper and is ducted inside.  The AB obviously provides much better control than the factory controller.   But to use it I need temperature readings from inside the camper.   I've searched the forums and read the user manual but haven't found anything that covers this.  All I can find is how to wire extra temperature sensors.  Is there a remote wireless temperature sensor or a way to accomplish this?

I'll post Ray's response from the FB group so I can find it later.

I have devised an Esp01 design that allows wifi temp sensing.I have devised an Esp01 design that allows wifi temp sensing.

Another suggestion was 
"Could you not just extend the three wires to the AB so as the Heater is outside and the AB is on the wall inside (extension cables are available on Ebay if you did not want to do it yourself)"

I have set something up that does the remote thermostat. Slightly more complicated but you can push a thermostat reading to the Afterburner over MQTT. It needs to be pushed every 20-30 seconds and will override the default thermostat reading. It's very effective but needs a good source of temperature. 
I have a Shelly HT G3 which produces a reading every 5 mins so have written some python code that updates the Afterburner every 20 seconds - based on the last temperature reading- if that makes sense?
