DuetWifi Virtual Heaters 101/102 in RRF3

Hi there,
I am a bit confused- In RRF 2.x I used M106 P2 T45:65 H100:101:102 to control the Mainboard-Fan.
In RRF I go with:

M308 S2 Y"mcu-temp" A"MCU Temp"	                ; Configure sensor2 at thermistor on pin e1temp for MCU
M308 S3 Y"drivers" A"Drivers Temp"	        ; Configure sensor3 as temperature warning and overheat flags on the TMC2660 on Duet
M950 F2 C"fan2" Q100		                ; Set fan2 to be fan2, PWM signal inversion (not inverted) and frequency
M106 P2 T40:65 S0 H2:3 C"Electronics Fan"       ; Set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned on

but I am missing the 102 input? The 101 (RRF 2.x) seems to be the "drivers"- but where is the 102? And if I enable the Drivers temp to be shown in chart it always reports 0.0°C?

What am I doing wrong?

Would be happy to get help

Do you have a DueX in your system? If not, then you don't need the third value. If you do, then create a third sensor with type "drivers-duex" and include that one in your M106 command too.

The drivers do not return actual temperatures, just normal, warning, or overheat status. These are represented as temperatures 0, 100 and 130C.
