Ver 1.5.0 Not Seeing 433Mhz Buttons

1

I have been running 1.4.0 lilygo-rtl_433 on a ttgo-lora32-v21 board. I have two 433Mhz buttons, same brand, that were being decoded as Smoke-GS558. Not exact, but usable.

Also under 1.4.0 I have a generic door/window switch. It was being decoded as Generic-Remote-28046 and Smoke-GS558.

When I updated to 1.5.0, the buttons are not seen any longer. No output on the serial port. The door/window switch is still being reported.

I reverted back to 1.4.0 and the buttons were seen again.

Any idea about how to fix this?

Thanks!

This is the door/window switch - seen as two devices.

With release 1.5 we did signal reception tuning to improve the overall ability of the receiver receive signals, so I wonder why this stopped.

If your doing your own builds, you can add this compiler flag which will log on the serial port the details behind any undecoded signals.

'-DPUBLISH_UNPARSED=true' ; publish unparsed signal details

This may offer a clue into what is happening.

I am happy to report that the updated rtl_433 library in the development version 04d7a2 has resolved this problem for me. Thanks for all your hard work!
