AgfaPhoto Frame (Frameo) - turn off display while keeping device reachable over WiFi

Hi everyone,

I’m using an AgfaPhoto Realiview APF2400WIFI (Android 10 / JoyHong board) as a Home Assistant dashboard. It runs Frameo together with Kiosk Satellite.

What I’m trying to achieve is quite simple:
Turn the physical display completely off via ADB, but keep the device awake/connected to WiFi so Home Assistant and ADB can still reach it and wake the screen again later.**

I can switch the display off successfully with:
input keyevent 223

The display is really off, which is exactly what I want. However, I’m currently testing whether the device eventually becomes unreachable over WiFi after being asleep for a while.

Interestingly, Frameo’s own scheduled sleep mode seems to behave differently: the display turns completely off, but the device remains reachable over the network.

Has anyone here managed to configure a Frameo/Android photo frame so that:

screen completely OFF → WiFi/ADB stays available → device can be woken remotely?

I’m not looking for dimming or a screensaver. The goal is specifically to have the display powered off while keeping network connectivity alive so Home Assistant can wake/control the device again.

I’m using Home Assistant’s androidtv.adb_command, so if there is a specific ADB command, Android setting, WakeLock/WiFiLock configuration, or another approach that works, I’d be very interested.

Thanks!
