Describe the bug
When a temperature offset is set the displayed temperature never stops incrementing the offset.
So with an offset of -10 it displayed -182 degC and keeps decreasing.

To Reproduce
Put any offset from the display menu and it will happen.

Expected behavior
Normal offset behavior.

Hi. Thanks for reporting this.

What temperature sensor are you using?

[Olaruci]

Hi, thank you for such a complete firmware for air sensors.
Is the built in temperature reported by Sensirion SCD30,
I have nothing else connected to the ESP32-TTGO-Display

Sensirion sensors calculate offset internally (in their own built-in firmware), CO2 Gadget just pass the offset value to the sensor.

The bug is that the offset must always be a positive number (it will drop temperature by this number and also will recalculate relative humidity).

I'll update the menu to only accept positive numbers.

While I do the modifications, please just change the "-10" temperature offset value to "10").

Note: Be prepared when you set an offset to not see the change immediately. Sensirion's firmware takes a while to adjust it (up to some minutes).

Thank you for reporting it. 😀

With positive offset it seems like nothing happens. I've let it 24h...

Thanks for reporting it, I have been able to replicate it and it seems that there are still some errors.

I'm going to look at it in depth because at first glance I can't see anything wrong.

I think it's fixed now. I tested it and it's working fine on my end.

As the fix is not included in the release version, I compiled a beta version just for you so you can check if it's working fine and report before I insert the modifications in the general release version.

Please, install it from here (be sure to choose the one stated as "CO2 Gadget Beta-Development Version"):

After flashing, please make sure it's running the right version: CO2 Gadget Version: 0.9.010 Flavour: TTGO T-Display Sandwich

Thank you! :-)

Hi , I don't have the Sandwich version, the regular TTGO T-Display

Hi, I don't have the Sandwich version, the regular TTGO T-Display

Opps! I'm very sorry, I oversaw that.

I just compiled a new version for you.

Please, install it from here (be sure to choose the one stated as "CO2 Gadget Beta-Development Version"):

After flashing, please make sure it's running the right version: CO2 Gadget Version: 0.9.014 Flavour: TTGO T-Display

Thank you! 😇

[Olaruci]

Thanks.
Yes now the offset is working. And is limited to be positive 0-30.

On information page didn't show 9.014 but is for sure the beta you provided.

[melkati]

Great! Thank you.

The fix will be included in the next release in the next few days (we are finishing some more fixes and improvements).
