For the Froling display, I had the sheet metal cover, found a box that it would fit, cut out the openings for the meters, painted the cover red to match the Froling, and then used stick-on lettering. Data recording can be useful, especially to spot and diagnose any anomaly. I also use DS18b20 sensors to do this. My latest foray into temperature data recording is with a Raspberry Pi computer running a Python program. I did the programming myself, using available programs in Python and then modifying them to do what I wanted. The RPi can handle multiple sensors and with the Python program can be customized and is very flexible. I am hoping this winter, when I have more spare time, to add programming for control (off-on) of devices, like circulators, valves, fans, etc.
