@teacdance
1-wire isn't supported in uiflow .. you will have to add an 1-wire to i2c converter: DS2482 -> https://community.m5stack.com/topic/1796/ui-flow-support-for-onewire-and-ds18x20/10
But you can use the MCP9600 with UIFlow (I2C-protocol).

Are you using the max6675 hooked up directly to a M5stack core ? UIFlow doesn't support SPI, but you can use Micropython as described in https://community.m5stack.com/topic/1845/micropython-spi

The M5Stack Kmeter Unit uses the max6674 and an esp32 with dedicated firmware as a SPI to I2C in addition to a thermocouple reading to temperature converter. The M5Stack Kmeter Unit has a red grove connector (I2C) and is supported in UIFlow.
