Imagintronix offset on v79

[kylegordon]

Evening all,

2 weeks ago I upgraded from firmware 78 to 79 on my rfxtrx433, and all is well except data from my collection of cheap Imagintronix temp & humidity sensors. They're all reading about 50 degrees higher than before the firmware upgrade - graphs at https://www.flickr.com/photos/kylegordon/15300824363/

Is this to be expected and they all need a -50 calibration tweak, or is it a bug that needs raised?

Cheers

Kyle

There is no change in V79 for the Imaginetronic, at least not intended.

What happens if you go back to V78?
Please contact support if there is really a 50 degrees offset in V79 compared to V78.

[kylegordon]

Yup, can confirm. Dropping back to v78 causes the sensors to return to approximately normal.

Will drop an email to the support line

A special firmware has been sent Dec 1st but no response yet.

Problem cannot be reproduced.
No response from kylegordon, problem call closed.

Been abroad for 5 weeks. Back soon, and will try to reproduce again when I'm local to the environment.

Hey,

Back from holidays and all refreshed...

Tried upgrading to v83, and sadly the Imagintronix sensors are reading too high. This is from moments after the upgrade, in Domoticz

Happy to run whatever diagnostics you wish.

Could it be that the temperatures are in Fahrenheit while the message says Celsius...

check what is received in RFXmngr

Hi folks,

This is the RFXmngr output from versions 78. 79 and 88, with respect to the Imagintronix/Viking sensors. All readings were taken within half an hour, and the temperature stayed around the same.
