Thanks. I found that in units.py and was reading the comments about the value tuples. I assumed that the "target units" was whatever was defined in weewx.conf. I am new to Python and objects, really, since it's been over twenty years since I wrote anything. What it looks like to me, for the

Function weewx.units.convertStd() is what you want. For example, to convert from Celsius to whatever unit system the LOOP packet is using: new_valueTuple = weewx.units.convertStd((22.5, "degree_C", "group_temperature"), packet['usUnits']) If you haven't run into them yet, read up about "ValueTup

I know I saw, somewhere, a way to call an existing weewx method to convert units to whatever is needed, but I can't find it again. It may have been in a service in the Wiki rather than in the documentation, because I can't find it there. Is there such a thing? I didn't like how limited the A

I have given up on trying to use the SPI interface with my own code. It works using code I found using pigpio, but, ultimately, I decided to just use the i2c interface and branch the i2c pins to allow my RTC to keep working. It works using i2c and the Adafruit software. This weekends project,
