Home automation projects have been popular as long as microcontrollers have been available to the general public. Building computers to handle minutiae so we don’t have to is one of life’s great joys. Among the more popular is adding some sort of system to a garage door. Besides adding Internet-connected remote control to the action of opening and closing, it’s also helpful to have an indicator of the garage door state for peace-of-mind. Most add some sensors and other hardware to accomplish this task but this project doesn’t use any extra sensors or wiring at all. In fact, the only thing add ..read more

If you’re lucky enough to have central heating and/or air conditioning, with an automatic thermostat, you probably don’t have to worry too much about the outside temperature. But central HVAC is far from the only way of maintaining temperature in a home. From wood stoves to boilers there are many options depending on your climate and home type, and [Murphy’s Law] has a decentralized baseboard system instead of something centralized. An ESP8266 solution was found that was able to tie them all together. There are other types of baseboard heaters, but in [Murphy’s Law]’s case the heaters were el ..read more

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 tak ..read more

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 “appli ..read more

Touch-screen control and monitoring 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 2 ..read more

Your home is your castle, and what’s better than a fully automatic castle? Nothing! That’s why we’re inviting you to submit your sweetest home automation hacks for a chance to win one of three $150 DigiKey gift certificates. The contest starts now and runs until April 16th. [Matej]’s Home Buttons gets the job done in open-source style.We love to play around with home automation setups and have seen our fair share, ranging from the simple “turn some lights on” to full-blown cyber-brains that learn your habits and adapt to them. Where is your project on this continuum? Whether you’re focused on ..read more

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 ..read more

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-p ..read more

One of the biggest upsides of open communications standards such as CAN or SPI is that a whole world of vehicle hacking becomes available, from simple projects like adding sensors or computers to a car or even building a complete engine control unit from the ground up. The reverse is true as well; sensors and gauges using one of these protocols can be removed from a car and put to work in other projects. That’s the idea that [John] had when he set about using a vehicle’s dashboard as a information cluster for his home. The core of the build is an Astra GTE dashboard cluster, removed from its ..read more

Bed sensors do sort of sound like a gimmick — after all, who cares whether someone is occupying the bed? But if you think about it, that information is quite useful from a home automation standpoint. A person could do all sorts of things in this state, from ensuring the overhead lights in the room can’t come on, to turning off other smart devices that are likely not being used while both occupants are sleeping. [The Home Automation Guy] presents a couple of ways of doing this, but both center around a fairly inexpensive pressure-sensing mat. In the first method, he connects the pressure mat u ..read more
