Quick Question on that: Has John implemented this in the DRAWS Manager? Does not appear to be the case. At the bottom of current version, the status bar says:
Digital Radio Amateur Work Station | Adapter: bcm2835 I2C adapter • +12V: +13.68 V • in5: +2.50 V • User ADC 1: +0.01 V • User ADC 2: +0.00 V
Raspberry Pi 4 Model B Rev 1.2 | CPU Temp: 108.24° F (42.36° C) • Uptime: 21 hrs 49 mins • Load AVG: 1m:1.07 5m:1.19 15m:1.17
Not in a hurry to do this, but the replacement board is working well… Many thanks.

DRAWS Has an on-board ADC to monitor the 12V supply. Sometime after the first run, 5V monitoring was added, but the config file wasn't updated so the sensors command doesn't work correctly.
the fix is to change /etc/sensors.d/draws as follows:
pi@K7UDR:/etc/sensors.d $ cat draws
#DRAWS uses the TL024 Which is SW Compatible with thw ADS1015
#It's an 8 Channel ADC, but only 4 Channels are pinned out
label in4 "+12V"
label in5 "+5V"
label in6 "User ADC 1"
label in7 "User ADC 2"
compute in4 ((48.7/10)+1)*@, @/((48.7/10)+1)
compute in5 ((10/10)+1)*@, @/((10/10)+1)
pi@K7UDR:/etc/sensors.d $ sensors
Adapter: ISA adapter
Adapter: bcm2835 I2C adapter
+12V: +13.52 V
+5V: +5.06 V
User ADC 1: +0.00 V
User ADC 2: +0.00 V
