What is the current FW version we can upgrade to for the PCB 4.2?

Flashing of the Wemos D1 Mini
#1

Hello,

I’m having trouble understanding what version I can upgrade to. It appears the PCB 4.2 is the board for the D1 mini? And if so, this link says the new FW is not supported on it AirGradient ONE (I-9PSL) and Open Air (O-1PST) Firmware Versions

I just want to update the FW of my PCB 4.2 unit and support features like dimming the OLED display, which currently does not work via the air gradient dashboard, despite the option being there.

Thank you

The last thing I can find from Achim is here:

Test Version for PCB v 4.2 with HA Support and Other Features - AirGradient Forum

Although, I hope that Achim can chime in and provide an update on where they are at with a new stable firmware for the D1 mini versions.
