It beeps, on the other end of the house (or on another floor), where it's inaudible.

I'll just add this tip for those who struggle with this sort of thing. I leave the empty basket in front of the machine, which for me happens to be somewhere where I'll pass by frequently until I need to take it out. That keeps it 'in sight, in mind'. Heck you could even put it in the kitchen to remind you. I don't like the extra complexity that often comes with digital solutions, but I do like having a system. The s…

My pro tip is one of my girlfriends scrunchies stolen and put on my wrist - annoys me intermittently and therefore repeatedly reminds me to check the laundry.

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. [1] https://mjones-foui.no/img/wall_clock_1.png

OpenMeteo is pretty amazing too, and doesn't require an account or API key, which is nice.

I incorporated OpenMeteo into a project recently and got frustrated with their aggressive rate limiting. If in the US, weather dot gov has an excellent, free API. Or, OpenWeatherAPI which works internationally and has support for more things that weather dot gov does not. OpenWeatherAPI will also synthetically provide weather data based on their models if there is missing station data

You can set an alarm on your phone when it starts like millions of people do instead of spending $2000 overengineering a solution to this "problem". The fact that people are complaining about the cognitive load and beeping sound when running a washing machine is utterly baffling to me. This goes beyond sheltered "first-world problems". There is something insidious about this about micro-optimising for non-issues, som…

> You can set an alarm on your phone Not all washing machines have static wash times, some (like ours) adjust the time based on what you actually put into it. Not to mention there are like 5-6 different programs we use, who has time to remember kind of how long time each program takes? And it doesn't display how long it'll take until it measured the load, which takes 2-3 minutes. So instead; chuck in the clothes and…

I would like to suggest a third alternative which is to set an alarm for the maximum time it will take. The HA option is more fun though for sure.

I need to know why the opposite of 'rain' is 'yo'.

The sun is greeting you! I drew these freehand, kind of quickly. And while I personally like the style and think it's a good fit for us, I did intend to make several sets of weather icons. At the very least I need to make the sun symbols adapt to the seasons - we don't really have a full sun during the darkest months of the year where I live.

Gonna piggyback here to second this and chime in to say I went with the BYOD screen linked within your link for $49 (SKU 104991005). It's definitely more barebones and probably not even as cost-effective if you're still planning on buying the "lifetime" TRMNL API access. I don't have easy access to a 3d printer, so I just have mine sitting on an extra phone stand I had lying around that can be had for a few bucks fro…

FWIW you need to pay for the trmnl key ($50) to use your own device with their servers, but if you run a server yourself you don’t need to pay. I’m very tempted, a lot lower resolution than a kindle but it’d be pretty cool.

i could have been clearer about that. but yeah, even for what i paid, i was happy to immediately be off to the races designing the couple panels within their web portal and having something functional and useful to me without any real friction from having to figure things out.

moving on to the self-hosting side is probably now backburnered indefinitely, even if i do have some grander ideas in the longer term. unfortunately, i'd need more than a weekend project's timeframe to bring them to fruition.

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.

My solution was to buy a used Samsung tablet with OLED screen, and control the display on with motion sensors. It sits in the hallway, above the keys drawer. The screen is on only when someone's walking nearby, and around eye level when you go pick up the keys. Designed the dashboard based around muted colours on black background, with brights reserved for "hey pay attention to this" data. And most importantly, the s…

Would love some details how you enabled controlling the display with motion sensors.

> For example the washing machine. You dont need real time information because you know how long it takes since you've done it 1000s of times and it beeps I'm not sure this is true anymore, first you usually do different programs depending on what you put into it, and modern washing machines also automatically adjust the washing time depending on how much you throw into it, at least our ~2 year old one does, I'm sure…

I can't imagine a world where the state of my washing machine is so important that I need to be interrupted to tell me it's done.

I can't image being so busy that hanging the clothes for 10 minutes could be seen as not important. We all live different lives :)

Besides, the notification is for notifying us, doesn't mean we need to do it within N minutes, it can wait until your Very Important Business Call is over or whatever. As long as it's done before it starts to get overly humid and starts to smell.

You have a newborn, and you think spending time installing and maintaining something that displays the calendar around the house is a good use of time?

I said "thinking about"... I have been thinking about many other things I wish I had time for too, like "getting eight hours of sleep" or "responding to a growing pile of emails that need attention". And while your rude, completely unnecessary comment displays a lack of the basic human empathy that may be necessary to understand this, it is precisely during a time when my life and home are so busy and chaotic that I…

> displays a lack of the basic human empathy

You don't know what goes on inside my mind, you're just guessing.

I have a 4 year old and my point was that the trade off of having a calendar on the wall in exchange for having to learn hardware and maintain services is absolutely awful. Of course everybody wants their life more organized, but my point was this project actually costs you something a lot more important. I have an infinitely long list of things that I'd rather do than adding services for myself to maintain, in exchange to having a calendar on the wall, for example actually spending time with my kid.

I empathize with you even though you don't appreaciate it.

So, I'm not going to say "sorry" because I don't think I did anything wrong. Instead I'll say that if I had known you'd take it that badly I wouldn't have said anything.

I would like to suggest a third alternative which is to set an alarm for the maximum time it will take. The HA option is more fun though for sure.

But why? Why add a manual, less accurate step instead of just using HA and solving it once? Steaming takes 20 minutes, a quick wash is ~1h, a boil wash more like 4h.

Why do I want only my phone to have a notification? Why do I want it to override other settings and go off at a set time rather than when I choose to interact (as a notification would)?

You can absolutely solve this in other ways, but adding an automation into HA for notifying me about forgetting to setup the dishwasher took a few minutes max and I only had to do it once.
