You know what, that is a great idea for a project of mine, where I want to display outside temp and weather forecast in the hallway next to the wardrobe. I have been musing about it for a while now: how to make it small and not stand out, how to handle power delivery, etc.
I was already leaning towards eink, and if I can get one of these price tags cheap plus hide an IR blaster in a corner that would be ideal. All controlled by Home Assistant of course. I'm going to search the usual Chinese online marketplaces tomorrow.
Thank you!
I had a look and knew they seemed to be about £15 here, I couldn’t easily find second hand ones in the uk (though they’re not uncommon at shops). For £40 I can get a 7.5 inch black and white screen setup (trmnl byod xaio https://www.aliexpress.com/item/1005009532501677.html)
Lots of the tags I see though do have Bluetooth or maybe WiFi for updating as well.
I do really like eink things, I want to setup a nice 13 inch one which is now more like £160 so becoming more realistic for my to buy for fun.
I’m going to have to look more into these tags because if there’s cheap second hand ones they’d be awesome.
Just look on eBay. It's full of used electronic shelf tags, sold in bulk -- usually, with prices still on them. :)
The sellers don't know anything about how they work so it will take some digging to find the right ones, but having to dig a bit is normal for eBay (or Aliexpress, for that matter).
*was full ;)
Maybe check out TRMNL, they've got a Home Assistant plugin.
