This is super cool, and I wish something like this existed at my place, as it enables information sharing without the need for phones/actual screens that shine in your face when the lights are low or tempt you to doomscroll.

That said, the large primary display this uses is $2000. That's very hard to justify for any "normal" household, and that's without any mounts, backend, services etc.

I made this thing [1] for us, it uses a cheap 10" e-paper display off aliexpress, an ESP32 and a couple of I2C sensors. The case is 3D-printed. It runs on two 18650 batteries, and all in all it cost less than 100$. The OpenWeather API is free for personal use.

You can make smaller ones for much much less. I’ll post pics of mine a bit later but waveshare 7.5” display in a photo frame and almost any ESP32 dev board and you are set for less than $100 (along with suitable HomeAssistant and ESPhome infrastructure to support it). The original article is a very slick bit of work, so well done

There are a couple of options for a large, non-backlit, low power display that are less expensive than the e-ink monitor they're using. One is the Samsung EM32DX, a 32" color e-ink digital sign for <$1300 (<$1000 if you can find it on sale) but it has a long refresh time. The other is the SVD rE 32" reflective LCD monitor for ~$1000, but it needs to be in brightly lit rooms because of its low contrast.

OP's Timeframe looks rad, but yes on the pricy side. check out trmnl .com for smaller / less expensive options and self hosted options. (disclaimer: i'm on the team)

I have a similar setup at home with a homemade dashboard. It's less polished and I've never implemented smart home (don't use any smart home devices) but it's calendar, weather, air quality and subway alerts. I also took the tack of building the UI with Bootstrap 3 so that it will run on any of my ancient devices like a gen 2 ipad air. I did it as much to usefully recycle old screens as anything else.
