I still haven't received a solid answer and I'm a bit confused. So there is currently no way to directly send some data from a RPi to the Duet Control Dashboard?

@dc42 Thank you for the information, I appreciate it. Is there any documentation available about what I am trying to achieve by connectng a RPi to the Duet2Wifi in order to visualize the data in the Duet Control Panel?

Hello,

I have a ToolChanger with a Duet2Wifi board running RepRap Firmware which I want to use for a process monitoring project. I need to measure the temperatures of all NEMA motors, cold end, ambient and possibly the heatbed. I also need to do vibration analysis measuring accelerations on the extruder and carriage.

I was thinking of measuring all of these using Raspberry Pi/Arduino, PT1000 sensors, ADXL345 accelerometer and somehow sending the data to the Duet2WiFi in order to integrate it into the Duet Dashboard to visualize the data. At this point I am not sure if this is possible and couldn't find any resources for what I am trying achieve.

During this research I also found out the RepRapFirmware 3.3beta3 and 3.3RC1 include experimental support for connecting LIS3DH accelerometer, so this might be a viable option. If I were to use this option, I need to know how many additional PT1000 sensors am I able to directly connect to the Duet2WiFi. Is it possible to connect 6-8 PT1000's and integrate them along with the LIS3DH accelerometer into the Duet Dashboard without having to use an Arduino or Raspberry Pi?

I would be very greatful if somebody could lead me into the right direction, thank you!
