It is an anticlimax to wrap up the Ink Bird as the digital thermostat and control for the Dometic refrigerator. I dread the final steps which involve running a cable from above the burner hobs over through the overhead cabinets, down the closet to the water boiler compartment, then into the cabinet that houses the refrigerator.
The most difficult part of the wiring is to preserve the thermistor for the Westfalia's Central Display Console so should the Ink Bird fails on the road I can easily relinquish the control back to it. feeding and squeezing the soft thermistor cable of the Ink Bird requires some tricks to get it up and then into the confined entry point of the cold box was very hard. Of course if I just cut out the incompatible thermistor and use the already routed cable life would had been so easy, except I would lose the ability to swap controller by simply plug and play.I took few photos for these final steps as I was also making wiring run for the electrical connections for the closet lights and wiring up the refrigerator control as well as tidying up everything, all after sunset.
power for the Ink Bird was taken from the connectors for the black water level indicator; the landline cable's four conductors is perfect for the interface to the Danfoss compressor electronics
Everything works. These include the ventilation fan, the closet lights, and most of all the heavily hacked Ink Bird temperature controller for the refrigerator. It would turn out that the red LED display for this Ink Bird is not distracting at all to be illuminating at night, for two reasons. 1) From the beds the light of sight is nearly tangential, and 2) the display is much dimmer than the one for the air conditioner.
Because of these, I see no reason to invest the time and effort to hack in a display enable switch.
