Hardware : Raspberry Pi 3 Model B Rev 1.2 one EMC2101 (GPIO 2 SDA and 3 SCL) tried 3v and 5v : both working one 12V fan + powersupply : Tach (white) - +12v" - Gnd - pwm(Blue) : Fan Nidec ta450dc, Gnd connected to Gnd GPIO RPi Octopi fresh install version 0.18.0 : tool raspberry Pi imager Octoprint : 1.7.3 Python 3.7.3 I2C enabled (sudo raspi-config) plugin EMC2101 installed from plugin manager

Wiring and EMC tested with Arduino : Working I2C tested with an SSD1306 Screen : Ok

EMC2101 initialized but no fan pwm and no Temp displayed on plugin screen "Fan Control (EMC2101)" everything is "Off" "Temperature" screen displays only Tool and Bed temps

Errors in octoprint.log :

Boot then :

Tried to heat up to 30 degree but no effects....

Look like plugin initialize but can't run every 2s and can't update pwm EMC2101.... any ideas? I can do more tests but my python's skills are not really good... Thanks

I've downgradeed to 0.0.4 and it's working :

[JeremyLaurenson]

Let me take a look, sorry for the issue.

[etellier]

Hi Jeremy. I've tried another version : 0.0.6 and it is working. the bug is just with last release. Thanks for your time and work.

[cybergurke]

I can confirm the behavior with the last release.

[be221b]

Same issue. Any fixes?

[JeremyLaurenson]

Ok, I believe I just pushed a working fix in 0.0.8 - please confirm if you would.

[cybergurke]

Thank you, its working now. How can I get the temps to the Temperatures tab?

[etellier]

Thanks, it's working now with a single EMC2101.
