AirGradient DIY v4

[johnjohn]

Hello,
I know that this setup is no longer supported, but I have a v4 board and soldered myself all the components.
Flashed the firmware via Arduino IDE and everything worked for around two hours. Then the display became static at the temp reading.

Turned off and on and now the display shows the message “init 1014”.
Does anyone have any idea what could be the issue?
Tried another SHT30 and result is the same.

I followed this guide:
https://www.airgradient.com/documentation/kb/kb-old-instructions-the-airgradient-diy-air-quality-sensor-basic-version-pcb-version-4-0/

Instead of the SHT40 I have an SHT30

Thanks in advance.
