Refractory Curing Box is now Heated

The heat is controlled by an ESP8266 which reports via wifi.  Using Mosquito an Node-Red.

Need to get a pic of the probe.

This process is not touchy enough to need a PID controller.   Set temp is 60F/15.5C with a hysteresis of 1/2C degrees.  Its holding nicely in a 3 degree C range.  May tighten this up but no hurry.   Maybe use a smaller heater or a 50% duty cycle while heating so no.

Graphs from first night.  Had a problem around 5:30AM.  Reset the controller.  Still need some work on the code but its up.
