Large format E-ink displays are currently used primarily in digital signage scenarios (outdoor advertising, passenger information systems,...) - examples are Soofa (http://www.soofa.co/) and Mercury Innovation (https://www.mercuryinnovation.com.au/digital-bus-stop).

The largest size currently available is 42" and it is used in outdoor and indoor scenarios. Indoor use is for education purposes as a digital whiteboard - see Quilla (https://www.engadget.com/2017-01-03-quirklogic-s-quilla-is-a...).

None of these are especially applicable for home use due to the price tag (just to be clear, the display itself is very expensive). What you could do is use Sonys larger format eInk tablet, use Remarkable EInk tablet or hack your own solution from an older Kobo reader.

We're offering solutions somewhere in the middle - traditionally we were focused on SME, where our devices are being used as universal digital signage (http://www.visionect.com) or tailored for room booking (http://getjoan.com), so a bit pricy for home use. But we just launched a 6" device called Joan Home (https://getjoan.com/shop/joan-home/) that syncs to your calendar and are looking to expand it with new functionality in the future. We're thing of integrations with home automation, pomodoro timer, IFTTT, etc...

Comments on the Joan Home are welcome - as we're actively thinking of developing this into a more feature rich product in next two months.

What a cool product for meeting rooms! But .. and maybe I'm just not the target audience, there's no way in any universe am I paying 250 bucks for a "do not disturb sign" in my house. That's just way too expensive.

Same here. My girlfriend just listens whether I'm talking to someone or not. If it's unclear, she taps on the door.

With kids I bet it's more difficult, but I don't think this technological solution can solve a human/social problem.

[luka-birsa]

Yup. We did get a lot of that with our meeting room solution. We'll be expanding the feature set over the near future, to entice home users to go for something like this even with a price tag of 250.

I can't even imagine what you'd add to make it useful for 250 dollars. Like, look.. If I don't want to be disturbed, I close my door. If I am OK with being disturbed, it is open. That's not going to cost me 250 bucks. If the product were in the 100 bucks range, maybe I'd bite, but it is far from that. This is trying to be pitched to me as a home solution, but with the price tag of what I'd consider for a company instead.

I don’t see what your problem is with the device - it’s an e ink calendar for 250 euros thats cordless, I like it. Even tho it is expensive for me.

“ Comments on the Joan Home are welcome - as we're actively thinking of developing this into a more feature rich product in next two months.”

Just giving my feedback. Like I originally said, it’s a cool product, but it’s got a price tag that makes it not a “Home” product like you just said.

This is "special offer" for home usage (in Europe for 249€ excluding VAT). Also "Comes with a FREE 30-day Joan Home plan trial" that I can't find anywhere on they page how much it cost or what is providing. Does it even work without this plan?

Jean-6 that's the same device plus front light cost 549€ (without VAT) and monthly premium plans.

I‘d love to see such a device based on Android with 5 years update guarantee. Users could easily use it for any of your envisioned use cases and you could focus on your hardware competency

Android will never work in a cordless scenario. We have device with 3 months autonomy and the next gen device currently nearing production drastically increases that as well. We've evaluated everything embedded, especially Android (love the ecosystem), but there is literary no tech that would give you full operation and full wifi connectivity, months of autonomy off a standard phone battery and Android. We had to develop a lot of proprietary stuff...
