[BUG] Awtrix / Ulanzi Temp_Offset is not working properly

[AndreasvonSchleinitz]

Bug report

Hi, I have the problem with the Temp_Offset function, no matter what negative number I enter it is ignored. All other functions (e.g. Hum_Offset) work without problems. The whole function is: { ‘temp_dec_places":1, ‘temp_offset":-9, ‘hum_offset":37 } and is located in a dev.json file. But it does not work. I have noticed that a positive offset is executed, but a negative one is not.

I would be glad if one of you knows some advice.

Add a description of the bug. Detail the expected behaviour in contrast with the behaviour you're observing.

Additional information

• Devices involved:
  • Model: Ulanzi Awtrix Smart Pixel Clock 2882 (TC001)
  • v 0.98

To Reproduce

Steps to reproduce the behavior:Just saving a dev.json

Expected behavior

Showing the offset on the device

The json is invalid youre using ‘ instead of "

Also, make sure you have no trailing or leading space in your json. The awtrix filemanager shows you any error on the left side of your text

this works as it should:

{
  "temp_dec_places": 1,  
  "temp_offset": -30,  
  "hum_offset": 0  
}

Hello Stephan,

surprisingly, it worked once when I copied your code line directly and did not change the values. When I then adjusted the temperature offset to -7, this change was ignored. Hum and decimal places, however, were adjusted.

All the best, Andi

I'm having the same problem. Temperature was on 29 degrees, seems I have to use -18 to get it to 20 degrees...

i dont think its the same problem, because everything is correct.

you need to note, that by default the offset is -9 according to the documentation. So when its showing 20° its actually 29°. If you set the offset to -9, its the same as the default value and nothing changes. so -9 is your zeropoint in this case and you need to calculate from this. OR set it to 0, read the Temp and then calculate your offset.

But you must also understand that you will NEVER get the right temperature. The sensor sits in the housing and is heated to different degrees depending on the number of illuminated pixels , color, brightness, etc.
