I want to read the temperature from my solar water heater controller. Is there a computer vision solution that can run on an old phone aimed at the display?
I thought about tapping into the temperature sensor that it’s already using, but I don’t want to compromise the controller’s operation.
I also thought about using the Fibaro Smart Implant to read the temp off a pipe, but that will be cool until hot water is flowing through the pipe.
I’m hoping that there’s a computer vision solution, or other option, to get the temp that the controller has.
If this should be posted elsewhere, please let me know.
