Insteon Abruptly Shuts Down, Users Left Smart-Home-Less

April 25, 2022 by Arya Voronova 88 Comments

In today’s “predictable things that happened before and definitely will happen again”, Insteon, a smart home company boasting the Insteon ecosystem of devices built around their proprietary communication standards, has shut down their servers without a warning. For almost two decades, Insteon used to offer products like smart light switches, dimmers, relays, various sensors, thermostats – the usual home automation offerings, all linked into a cozy system. Looking through the Insteon subreddit’s history, there were signs of the company’s decline for good half a year now, but things were mostly stable – until about a week ago, when users woke up and noticed that parts of their smart home network stopped working, the mobile app would no longer respond, and the company’s resources and infrastructure went down. What’s more – the C-rank management has scrubbed their LinkedIn profiles from mentioning Insteon and SmartLabs (Insteon’s parent company).

Instantly, the Insteon subreddit has livened up. People, rightfully angry about being literally left in the dark, were looking for answers – as if mocking them, Insteon’s homepage claimed that all services were operational. Others, having expected the shutdown to eventually happen, started collecting and rehosting rapidly disappearing documentation, helping each other keep their tech up in the meantime, and looking into alternative platforms. It turned out to be imperative that users don’t factory reset their Insteon hubs, since those have to communicate with the currently Inste-Gone servers as part of initial configuration, diligently verifying the SSL certificates. Sadly, quite a few users, unaware and going through the usual solutions to make their network function again, are now left with hubs that are essentially bricked, save for a few lucky ones.

Testing 7 Wago-like Wire Connectors For Science And Fire

April 25, 2022 by Maya Posch 31 Comments

At the intersection of saving a few bucks and expensive home insurance claims due to a house fire, we find clones of certified and tested electrical connectors, even when many would argue that so-called wire nuts are fire hazards no matter how many certification labels are on them. When it comes to no-fuss wire connectors, Wago clamp connectors are an attractive target to save some money on due to their perceived high cost. But how expensive are they really?

This was the thought behind a recent video by [GreatScott!] (also embedded after the break) when he hopped onto everyone’s favorite e-commerce website and searched for ‘clamp lever terminal’. The resulting selection of seven connectors come in a wide variety of shapes, colors and configurations, though all are supposedly rated for mains (250 VAC) voltage and safe enough to put into a permanent installation.

While running the connectors through their paces with high-current, fire and mechanical strength tests, the conclusion was that all are good enough for hobbyists use and some brief connections while testing, but that only the ones with independent certification marks (like VDE) filled him with enough confidence to consider using in house wiring. One of these being the connectors by the German brand ViD, which would seem to be a slightly cheaper alternative to the Wago connectors, with similar guarantees of safety.

At the end of the day it is the certification that matters, after all, since long-term reliability is of primary concern with house wiring, not whether a few Euros were saved on material costs.

2022 Sci-Fi Contest: Your Home Assistant, HAL 9000

April 23, 2022 by Lewin Day 17 Comments

Anyone who has seen 2001: A Space Odyssey will easily remember HAL 9000, the sentient computer that turned against its human companions aboard Spacecraft Discovery One. [Ben Brooks] decided to recreate the foreboding digital being, and put it to work as a smart home assistant.

The build consists of a 3D printed assembly that looks very much like HAL did in the movie. It runs as a standalone device hooked up to [Ben]’s Home Assistant instance, a self-hosted home automation solution. The device is capable of playing sound clips from the movie, with the help of an ESP8266 and a DF Player Mini module. It’s triggered by a button or motion sensor, but it’s also hooked up to Home Assistant for some extra smarts. This setup makes sure HAL stays silent when a Chromecast is playing content on TV, so as not to disturb essential viewing.

Overall, it’s a fun movie tribute build that is remarkably true to the source material. Let’s just hope this HAL doesn’t get any maniacal ideas, forcing [Ben] to pull apart its processor to stop its dangerous machinations.

We’ve seen some other great HAL builds before, too. Video after the break.

IoT Pool Monitor Helps You Keep It Crystal Clear

April 16, 2022 by Lewin Day 5 Comments

Having a pool is great, but it also requires significant monitoring and maintenance to keep it crystal clear and clean. The OPNpool controller from [Coert Vonk] aims to help in this task, integrating neatly into the smart home ecosystem of today.

OPNpool runs on an ESP32, and is capable of monitoring pool controllers, pumps, and chlorinators, as well as working with thermostats and other hardware to control the state of the pool. This allows the system to do useful things like run high-powered pumps when electricity is cheapest, or to find the best timing to run heating circuits. The controller relies on MQTT messaging and can integrate with Home Assistant for those that prefer to run their own cloud-independent smart home systems.

With WiFi onboard the ESP32, there’s no need for a hardwired LAN connection, and the system can be administered remotely over the web. It’s also capable of talking with other hardware over RS-485 and bringing it under its own control. With OPNpool installed, monitoring pool conditions can be done from the leisure of one’s deck chair with a smartphone, rather than squinting and dark LCDs in equipment cabinets.

It’s a useful tool that could be just the ticket for the savvy, IoT-aware pool owner. We’ve seen other DIY pool controllers before, too. With summer just around the corner, it’s the perfect time to get hacking!

A Turbocharged Robot Mop To Save Your Date

April 10, 2022 by Robin Kearey 4 Comments

Cleaning robots are great and all, but they don’t really excel when it comes to speed. If your room looks like a pigsty and your Tinder date is arriving in twenty minutes, you’ll need more than a Roomba to make a good impression. [Luis Marx] ran into this exact problem and decided to solve it by building the world’s fastest cleaning robot (video, embedded below).

[Luis] built his ‘bot from the ground up, inspired by the design of your average robot vacuum: round, with two driven wheels and some sensors to avoid obstacles. A sturdy aluminium plate forms the chassis, onto which two powerful motors are placed to drive a pair of large-diameter wheels. The robot’s body is made from 3D-printed components and sports a huge LED display on top that functions as a speedometer of sorts.

Building a vacuum system turned out to be rather difficult, and since [Luis] already had a robot vacuum anyway, he decided to make this a robot mop instead. A little tank stores water and soap, which is pumped onto a microfibre cloth that’s attached using a magnetic strip. Obstacle avoidance is implemented through three ultrasonic distance sensors: when the robot is about to run into something it will brake and turn in the direction where it senses the most empty space.

All of that sounds great, but what about the speed? According to [Luis]’s calculations, it should be able to reach 60 km/h, although his living room is too small to put that into practice. Whether it will provide much in the way of cleaning at that speed is debatable too, but who cares: having your own ultra-high-speed robot mop will definitely impress your date more than any amount of cleaning.

We’ve featured a home-made robot mop before, but it looks excruciatingly slow compared to this one. If you’re planning to build zippy indoor robots, you might want to look into fast navigation systems like tracking ceiling lights.

Wireless Weather Station Gets Solar-Powered Supercap Upgrade

April 7, 2022 by Robin Kearey 18 Comments

When [knight-of-ni] bought an Acurite Atlas weather station to replace his earlier 5-in-1 model, he was initally happy with its performance. However, after just ten months the batteries in the outdoor unit died; since the previous model would happily run for several years on one charge, this was a bit of a bummer. Climbing up on the roof more than once a year just to replace batteries was becoming inconvenient as well, so [knight-of-ni] designed a solar power system with supercap backup and remote monitoring that should keep the sensors running 24/7, come rain or shine.

The heart of the new power system is a pair of supercapacitors totalling 250 Farads, with an integrated protection circuit that limits the voltage to 5.4 Volts. The caps are charged by a 12 V solar panel; this means that quite a bit of power is dissipated in the protection circuit when the supercaps are fully charged, but since this is completely free solar power that is not much of an issue. A 6 V panel would have worked as well in full sunlight, but might have struggled on a cloudy or snowy day.

[knight-of-ni] wasn’t content with just letting the new power system run unattended however, and decided to integrate a remote monitoring tool as well. For this he used a Moteino, which is an Arduino-type board with an integrated 915 MHz transceiver. The data coming from this board is received by a Raspberry Pi running Linux and presented through a nice web interface. Thanks to this data [knight-of-ni] was able to confirm that the supercaps were fully charged in just an hour and a half on a sunny morning, and maybe three or four times that on a dark and rainy day.

If you’re interested in solar-powered weather stations, we’ve featured a few: some very simple, some more comprehensive, and one built into an IKEA lantern. If you’d like a recap on the working principle of supercapacitors and how they compare to batteries, look no further than our in-depth article on supercaps.

Thanks for the tip, [felix]!

You Can Turn Soft Drink Bottles Into Handy Solar Lamps

March 29, 2022 by Lewin Day 17 Comments

Solar lights are a popular garden decoration. Of course, they’re available cheaply from most hardware and garden stores, but if you’re more of the DIY type, you might like to build your own. [opengreenenergy] has done just that, using recycled materials for a cheap and simple design.

The design was inspired by the Moser bottle, which is a water-filled bottle used to diffuse sunlight into a room during the day. Instead of sunlight, however, this design uses an LED to provide the light, for decorating a garden or for use when out camping or traveling.

In this design, a solar panel is used to charge a lithium-polymer battery during the day using a LP4060B5F charge controller IC. It’s paired with a AP6685 battery protection IC to ensure the battery is not overly discharged or otherwise damaged in use. When the solar panel stops putting out power when it gets dark, the LED is automatically switched on. It can be set to a low or high brightness to provide more runtime or more light as needed.

All the circuitry is wrapped up in a neat 3D-printed case that allows the hardware to be screwed directly on top of a regular soft drink bottle. Paired with some water in the bottle, and perhaps a little bleach to stave off algal growth, the result is a handy, portable light that also has enough mass to avoid it being blown over easily.

It’s interesting to compare the design to commercial versions that aim to pare costs down to a minimum. Video after the break.
