I tried to figure out a way to control my frameo photo frame via home assistant. It runs on android and this software is shipped with a lot of frames. I wasn’t able to do so for now.
Would be nice to be able to switch the frame on and off and change the brightness via Home Assistant.
I haven’t tried controlling a Frameo with Home Assistant, but I totally get where you’re coming from. I had a similar challenge with my digital photo frame. I wanted to adjust the brightness at different times of the day, and it was a bit of a hassle to do it manually each time. But I found out that the Nixplay frame has an app with some cool features that allow you to schedule the frame to dim or brighten at specific times. It wasn’t quite as automated as Home Assistant, but it made things much easier.
