A Giga-Sunset For Gigaset IoT Devices

April 3, 2024 by 76 Comments

In today’s “predictable things that happened before and definitely will happen again”, we have another company in the “smart device” business that has just shuttered their servers, leaving devices completely inert. This time, it’s Gigaset. The servers were shuttered on the 29th of March, and the official announcement (German, Google Translate) states that there’s no easy way out.

It appears that the devices were locked into Gigaset Cloud to perform their function, with no local-only option. This leaves all open source integrations in the dust, whatever documentation there was, is now taken down. As the announcement states, Gigaset Communications Gmbh has gotten acquired due to insolvency, and the buyer was not remotely interested in the Smart Home portion of the business. As the corporate traditions follow, we can’t expect open sourcing of the code or protocol specification or anything of the sort — the devices are bricks until someone takes care of them.

If you’re looking for smart devices on the cheap, you might want to add “Gigaset” to your monitored search term list — we’ll be waiting for your hack submissions as usual. After all, we’ve seen some success stories when it comes to abandoned smart home devices – like the recent Insteon story, where a group of device owners bought out and restarted the service after the company got abruptly shut down.

We thank [Louis] for sharing this with us!

Retrogadgets: Butler In A Box

March 28, 2024 by 11 Comments

You walk into your house and issue a voice command to bring up the lights and start a cup of coffee. No big deal, right? Siri, Google, and Alexa can do all that. Did we mention it is 1985? And, apparently, you were one of the people who put out about $1,500 for a Mastervoice “Butler in a Box,” the subject of a Popular Science video you can see below.

If you think the box is interesting, the inventor’s story is even stranger. [Kevin] got a mint-condition Butler in a Box from eBay. How did it work, given in 1983, there was no AI voice recognition and public Internet? We did note that the “appliance module” was a standard X10 interface.

Supervisory control and data acquisition, or SCADA, systems sit in the background in industrial settings, performing all kinds of important jobs but in an ad-hoc setup, depending on the precise requirements of the installation. When we think about home automation systems, they’re pretty much the same deal: ad-hoc systems put together from off-the-shelf components and a few custom bits thrown in. [Stefan Schnitzer] clearly has significant knowledge of SCADA in an industrial setting and has carried this over into their home for their entry into the Hackaday 2024 Home Sweet Home Automation Contest.

Haier Europe Eases Off On Legal Threat And Seeks Dialogue

January 22, 2024 by 42 Comments

After initially sending a cease and desist order to [Andre Basche] – the developer of a Haier hOn plugin for Home Assistant – Haier Europe’s head of Brand and IoT has now penned a much more amicable response, seeking to enter into dialogue in search of a solution for both parties.

This latest development is detailed both in the ongoing GitHub issue, as well as the Takedown FAQ and Timeline document that [Andre] created to keep track of everything that’s going on since we last checked in on the situation. As things stand, there is hope that Haier Europe may relent, especially as the company’s US division has shown no inclinations to join in on the original C&D.

In the confusion following the initial C&D announcement demanding the take-down of [Andre]’s hOn-related repositories, it was not clear to many which Haier was involved. As it turns out, Haier Europe as a separately legal entity apparently decided to go on this course alone, with Haier US distancing themselves from the issue. In that same Reddit thread it’s noted that GE Appliances (part of Haier US) has had a local API available for years. This makes Haier Europe the odd one out, even as they’re attempting some damage control now.

Amidst this whirlwind of developments, we hope that Haier Europe can indeed reach an amicable solution with the community, whether it’s continued API usage, or the development of a local API.

Alarm Panel Hack Defeats Encryption By Ignoring It

January 19, 2024 by 23 Comments

As frustrating as it may be for a company to lock you into its ecosystem by encrypting their protocols, you have to admit that it presents an enticing challenge. Cracking encryption can be more trouble than it’s worth, though, especially when a device gives you all the tools you need to do an end-run around their encryption.

We’ll explain. For [Valdez], the encrypted communication protocols between a DSC alarm panel and the control pads on the system were serious impediments to integration into Home Assistant. While there are integrations available for these alarm panels, they rely on third-party clouds, which means that not only is your security system potentially telling another computer all your juicy details, but there’s also the very real possibility that the cloud system can either break or be shut down; remember the Chamberlain MyQ fiasco?

With these facts in mind, [Valdez] came up with a clever workaround to DSC encryption by focusing on physically interfacing with the keypad. The device has a common 16×2 LCD and a 25-key keypad, and a little poking around with a multimeter and a $20 logic analyzer eventually showed that the LCD had an HD44780 controller, and revealed all the lines needed to decode the display with an ESP32. Next up was interfacing with the keypad, which also involved a little multimeter work to determine that the keys were hooked up in a 5×5 matrix. Ten GPIOs on the ESP32 made it possible to virtually push any key; however, the ten relays [Valdez] originally used to do the switching proved unwieldy. That led to an optocoupler design, sadly not as clicky but certainly more compact and streamlined, and enabling complete control over the alarm system from Home Assistant.

We love this solution because, as [Valdez] aptly points out, the weakest point in any system is the place where it can’t be encrypted. Information has to flow between the user and the control panel, and by providing the electronic equivalents to eyes and fingers, the underlying encryption is moot. Hats off to [Valdez] for an excellent hack, and for sharing the wealth with the HA community.

Haier Threatens Legal Action Against Home Assistant Plugin Developer

January 19, 2024 by 109 Comments

Appliance manufacturer Haier has been integrating IoT features into their newer products, and as is so common these days, users are expected to install their “hOn” mobile application to access them. Not satisfied with that limitation, [Andre Basche] reverse engineered the protocol used by the app, and released a Python library and associated Home Assistant plugin to interface with a wide array of Haier appliances, which includes brands like Hoover, Candy, GE Appliances and others.

Unfortunately, it looks like his efforts have gotten him into a bit of legal hot water. In an issue recently opened on the project’s GitHub page, [Andre] explains the circumstances and legal options that have led him to consider pulling the repositories completely — mostly due to the cost of mounting a legal defense to the cease & desist from Haier Europe.

What’s ironic here is that Haier has been part of the Connectivity Standard Alliance (CSA) since 2022, whose goal is to ‘promote universal open IoT standards’, including Matter.

It’s possible that a legal defense will be mounted against this C&D from Haier within the coming days. Yet regardless of the outcome here, it remains problematic that these IoT-enabled Haier appliances are connected to the Haier servers. Ideally they would be controlled locally, which is the goal of projects like [Miguel Ángel López Vicente]’s ESP Haier, that uses an ESP8266 to connect Haier AC units to the local WiFi and e.g. HA instances, all without requiring internet access.

This is sadly just one more example of why building your own off-line smart home can be such an incredible struggle.

Thanks to [Ar3itrary] for the tip.
