Power Management in HAOS turns of the WLAN every time

[gomon1848]

Describe the issue you are experiencing

Hi,

as we all know, it is best to connect HAOS or HA via ethernet. However, if you have a Raspberry Pi with HAOS, you can connect HA via Wifi, as I do for reasons. In Linux it is generally the case that the power management (always switched on by default) switches off the WLAN after a certain time. This causes HA to go offline and you may have to restart the hardware several times if you don't want to connect a keyboard, mouse and screen. It is possible to switch off power management in a roundabout way, but this is only valid until the next reboot of the system. I did this with "iwconfig wlan0 power off" after installing iwconfig using "apk add wireless-tools" (by the way, wireless-tools disappeared again after a reboot). All common variants to do this permanently (for example, as with Raspberry Pi OS or normal Linux distributions) failed, as systemd, udev, or rc.local are apparently not available. I personally see this as a bug, HAOS should automatically recognise that no Ethernet is connected and then set the power management to off. Alternatively, it should be possible to select whether power management for WLAN should be deactivated or activated as a new item in the interface. Personally I see this as a bug and not a new desired feature, please let me know if I should submit this as a new desired feature. i hope i'm in the right place, i'm new to HAOS. BR
