Here's a short video about my cloudless, portable, small, low-resource "smart thermostat". It doesn't need an internet connection and uses MQTT. Here, it's directly driving a relay.
It's running on a Raspberry Pi Zero W, powered by NetBSD, in read-only mode.
I used it for years and it's time to go back to it, cloudless and local.#RunBSD #NetBSD #IoT #OwnYourDevices #OwnYourData #Cloudless

@stefano if you don't already have something in mind, this might make a very interesting conference talk. We've already had a FreeBSD Fridge. I think a privacy first NetBSD thermostat would be well received.
Here is a link to the FreeBSD Fridge from 2024 BSDCan. It is available on the SDF Peertube instance Toobnix.org: -

@stefano It's not that special to be honest but it's cool to have anyway!

@stefano I wish I could find the HN comment by the Honeywell engineer that talks about like 6 different safety features none of the open source DIY thermostats have but I cannot seem to find it anymore. Stuff like
- it needs to lock out instead of continuing to try to start the gas heat so you don't flood the house with gas if the ignition is faulty
- it needs to automatically turn on the heat no matter what if if gets too cold
- it needs a mechanical safety feature to shut itself off if the heat gets stuck on
etc etc -

etc etc@feld My Netatmo doesn't do all that, and neither do the other thermostats connected to the other boilers I have access to.
Fundamentally, those are things the boiler handles (if it's less than 20 years old), not the thermostat. My boiler, even though it's 10 years old, has all these internal features; it also controls the water temperature, etc.
The thermostat is just for deciding if the house is cold or not - I expect all the other controls to be handled by the burner itself.
In other words, I'm not replacing the internal thermostat (the one that regulates the flow temperature, etc.), just the room thermostat. Besides, my sensor is located very far from the boiler, which is in a separate, ventilated room.

@MisterMaker No, maybe it's not special. But it's mine, and solved a lot of problems in the past, when those smart things wheren't even available. Sometimes you don't need rocket science to have some fun 🙂

@stefano I wonder if this is perhaps a fundamental difference in design between some of the EU and US equipment.
Maybe it's only older equipment in the US that doesn't do this and Honeywell had to build it into the thermostat to cover themselves legally? -

@stefano For sure, it's fun! I have been putting these kind of no-cloud things all over the house lately :). This is my main thermostat for the house https://diyless.com/product/opentherm-thermostat3

@MisterMaker that's great - and funny! 🙂

@stefano Yeah, glad I keep my IoT stuff very isolated. It can't speak to the rest of the network at all.

Building A Clamshell Writer Deck
Most of us do our writing on computers these days, but the modern computing environment does present a lot of distractions. That’s let to the concept of the writer deck, a simplified device intended more specifically for word processing tasks. [Ashtf] has built a great example of the form with a modified version of the PocketMage device.
The PocketMage is a clamshell PDA device that [Ashtf] has been working on for some time. It’s powered by an ESP32, hooked up to a nice e-ink display. In its basic form, it’s not the ideal device for doing serious writing work, mostly because of its tiny keyboard. However, [Ashtf] has since added external keyboard support, which completely changes the game. With the use of a small USB C to USB A adapter, you can hook up any conventional USB keyboard that you like to best attain your maximum typing speed.
The result is a compact, simple device that lets you type away without distractions. If your latest fanfic isn’t coming along quickly enough because you keep losing focus to social media, perhaps this is a route you might like to go. [Ashtf] also included Markdown support so you can create richer documents on the device while operating in what is still fundamentally a text-only environment.
It’s neat to build custom devices that suit your own personal productivity needs. If you dig the PocketMage, you might like to check out the design files on Github. We’ve featured some other fun writer decks before, too. Video after the break.
