What sidjohn1 suggested, with extra comment: if you have option get a (used) tablet with OLED display. This way you’ll be able to program it so that clock will always be visible, just very dimmed. The point is that classic LCD’s can’t be dimmed low enough not to bother your sleep because of backlight, while oled’s don’t have backlight, so they can be dimmed to minimum plus font can be set to very dark grey - i use rgb(10,10,10) - which will cause clock to be visible only in total darkness (and even then only after a while when your eyes become accustomed to darkness). On the other hand, it could be any oled phone, if tablet is too big for you. You can get, say, Samsung S8 pretty cheap, and it can have battery exhausted…
I have old Samsung S5 tablet, i’m using clock card for time, for alarm i use scheduler card. Other things as desired, imagination (and some knowledge) is your limit.
Good point… missed the font part. So then it can do almost all the things you’re looking for.
I didn’t see anything about rows in the initial post, but to see alternate data, in my particular setup, every few minutes I have the temp and humidity display instead of the clock for 15 or so seconds. Then it switches back. Same with weather, every 15 minutes or so for 20 seconds or so. Alerts pop up, as needed and switch back to the clock after a delay or the alert clears.
(I also have a few tablets with their own dashboards, so this solution depends on room, taste, etc.)
I’d love to see what you ultimately decide on and deploy.
I’d started searching around for something like that a little while ago but was disappointed to find that a device that was a: not just a repurposed tablet/phablet; and b: not looking too homemade; and just kept finding single-purpose weather stations, sports score trackers and (exclusively) app-controlled and/or app-dependent displays. So not a good candidate for HA control without serious hackery, if at all.
I see some vague suggestions that someday there might be an API released for the Glance LED devices which would make a HA integration possible. That would be cool, but soon™ so often turns out to be never. Also, you have to be in the market for a vibe that might be described as “man cave” or “tech bro” so maybe not for everyone . . .
One of those flip-flap character displays would be sweet, too, but starting at 1000US I didn’t even read further . . .
The plan is a brass rectangle bent about 90 degrees coming from the backside of their beds out to the side.
Twisting the encoder will din the light in the room.
Push is on/off.
And the rest of the functions will be using the touch screen
There will be many sensors and switches exposed once added to HA - There’s a screen on/off, a mode switch for auto-dimming, a lux sensor, battery, temp humidity, button actions… it’s quite full featured.
