Power supply is loosing power?

[Licht2002]

Thx waltervl,

Yes - i use a new 4A USB-C Supply since yesterday, before it was a 3A USB-C.

Power supply is loosing power?

[waltervl]

And since then you have this issue?

[Licht2002]

No... the issue was before. I also thing, there is a Power-Problem...

And since then you have this issue?

[PieterS]

Maybe to many protocols enabled?? I thought the manual advise is only the ones needed..
And maybe to many other devices connected to your RPI?

[b_weijenberg]

Enabled protocols is no reason for this problem.
In most cases it is a bad power delivered by the RPI to the USB.

Try another USB cable, use a powered USB hub or use the RFXtrxLAN.
The RFXtrxLAN (LAN or Wifi version) has his own power supply and can be located on the best location for 433 receive and transmit.
