Bridging RTL-433 To Home Assistant

December 6, 2025 by Lewin Day 18 Comments

If you’ve got an RTL-SDR compatible receiver, you’ve probably used it for picking up signals from all kinds of weird things. Now, [Jaron McDaniel] has built a tool to integrate many such devices into the world of Home Assistant.

It’s called RTL-HAOS, and it’s intended to act as a bridge. Whatever you can pick up using the RTL_433 tool, you can set up with Home Assistant using RTL-HAOS. If you’re unfamiliar with RTL_433, it’s a multitalented data receiver for picking up all sorts of stuff on a range of bands using RTL-SDR receivers, as well as a range of other hardware. While it’s most closely associated with products that communicate in the 433 MHz band, it can also work with products that talk in 868 MHz, 315 MHz, 345 MHz, and 915 MHz, assuming your hardware supports it. Out of the box, it’s capable of working with everything from keyless entry systems to thermostats, weather stations, and energy monitors. You can even use it to listen to the tire pressure monitors in your Fiat Abarth 124 Spider, if you’re so inclined.

[Jaron’s] tool integrates these devices nicely into Home Assistant, where they’ll appear automatically thanks to MQTT discovery. It also offers nice signal metrics like RSSI and SNR, so you can determine whether a given link is stable. You can even use multiple RTL-SDR dongles if you’re so inclined. If you’re eager to pull some existing environmental sensors into your smart home, this may prove a very easy way to do it.

The cool thing about Home Assistant is that hackers are always working to integrate more gear into the ecosystem. Oftentimes, they’re far faster and more efficient at doing this than big-name corporations. Meanwhile, if you’re working on your own hacks for this popular smart home platform, we’d probably like to know about it. Be sure to hit up the tips line in due time.

Making Quinetic Gear Work With Home Assistant

December 2, 2025 by Lewin Day 2 Comments

There are lots of switches that you can use with your smarthome. Some might not be compatible with the wiring in your house, while others are battery powered and need attention on the regular. [Willow Herring] came across some nice self-powered versions that were nonetheless locked to a proprietary hub. Reverse engineering ensued!

[Willow] was using a range of smart home products from Quinetic, including the aforementioned self-powered switches. However, she couldn’t stand using them with the Quinetic hub, which was required to get them functioning with the brand’s relays and in-line switch relays. It all came down to the buggy smartphone app that was supposed to lace everything together, but never worked quite right. Instead, she set about deciphering the language the switches speak so they could be paired with other smarthome systems.

[Cameron Gray] had done some work in this area, which proved a useful starting point, though it didn’t enable the use of the switches with the various types of Quinetic relays. [Willow] decided to try and learn more about the system, starting with a CC1101 radio module hooked up to a ESP8266. Some tinkering around with expected message lengths started bearing fruit, and soon enough the format of the messages became clear.

Before long, [Willow] had figured out how to get the whole system talking to MQTT and Home Assistant, without compromising their ability to operate independently. Code is on Github for those eager to tinker further.

We’ve looked at a number of self-powered switches before, too. If you’ve found your own neat way of interfacing these devices, don’t hesitate to notify the tipsline!

DIY Light Panels Work With Home Assistant

November 29, 2025 by Lewin Day 2 Comments

There are a few major companies out there building colorful LED panels you can stick on your wall for aesthetic purposes. Most commercial options are pretty expensive, and come with certain limitations in how they can be controlled. [Smart Solutions For Home] has whipped up a flexible DIY design for decorating your walls with light that is altogether more customizable.

In this case, the DIY light panels ape the hexagonal design made popular by brands like Nanoleaf. In this case, each hexagon panel runs an ESP32 microcontroller, which controls a series of WS2812 addressable LEDs. This allows each panel to glow whatever color you like, and they’re arranged in an XY grid to enable you to light individual panels with a range of different geometric effects. The benefit of having a full microcontroller on each panel is that they can act quite independently—each one able to be used as a smart light, an notification display, or even as a physical button, all integrated with Home Assistant.

If you’re a fan of DIY smart home products, these might be right up your alley. They’re supremely flexible and customizable, and can do a lot of things that commercial versions can’t easily replicate. Just don’t ignore the fact that they require a considerable amount of assembly, what with the custom PCBs, 3D printed enclosures, and front diffusers to deal with. That’s just the way the LED wall crumbles.

We’ve seen other similar builds before, too. Why? The simple fact is that a lot of people want cool glowy panels on their wall without having to pay through the nose for them.

Smart Bulbs Are Turning Into Motion Sensors

October 7, 2025 by Lewin Day 33 Comments

If you’ve got an existing smart home rig, motion sensors can be a useful addition to your setup. You can use them for all kinds of things, from turning on lights when you enter a room, to shutting off HVAC systems when an area is unoccupied. Typically, you’d add dedicated motion sensors to your smart home to achieve this. But what if your existing smart light bulbs could act as the motion sensors instead?

Logitech POP Buttons Are About To Go Pop

October 6, 2025 by Maya Posch 70 Comments

For those who missed out on the past few years of ‘smart home’ gadgets, the Logitech POP buttons were introduced in 2018 as a way to control smart home devices using these buttons and a central hub. After a few years of Logitech gradually turning off features on this $100+ system, it seems that Logitech will turn off the lights in two weeks from now. Remaining POP Button users are getting emails from Logitech in which they are informed of the shutdown on October 15 of 2025, along with a 15% off coupon code for the Logitech store.

Along with this coupon code only being usable for US-based customers, this move appears to disable the hub and with it any interactions with smart home systems like Apple HomeKit, Sonos, IFTTT and Philips Hue. If Logitech’s claim in the email that the buttons and connected hub will ‘lose all functionality’, then it’d shatter the hopes for those who had hoped to keep using these buttons in a local fashion.

Suffice it to say that this is a sudden and rather customer-hostile move by Logitech. Whether the hub can be made to work in a local fashion remains to be seen. At first glance there don’t seem to be any options for this, and it’s rather frustrating that Logitech doesn’t seem to be interested in the goodwill that it would generate to enable this option.

How A DIY Chicken Coop Door Opener Went From Simple To Complex

June 13, 2025 by Maya Posch 18 Comments

How hard could it be to make a chicken coop door that can be configured to open and close automatically using a straightforward interface? That’s the question that [Jeff Sandberg] set out with, after three years of using a more basic off-the-shelf unit that offered no remote access nor a convenient user interface. The use case for [Jeff] was rather straightforward: the door would be open during the day and closed at night to keep the hens safely inside the coop.

The commercial solution offered an RTC-backed programmable interface as well as a light sensor, but the latter wasn’t always reliable in inclement weather and making simple changes to the programming when e.g. the hens had to stay inside a day due to work on the yard, was much more complicated than needed, plus had to be done on the spot. The new system would solve all these ills.

That said, the existing door mechanism was doing a fine job and could be kept. This just left making a new box with electronics to control it, starting with an ESP32C3 with the ESPHome firmware that is hooked into the local Home Assistant system, along with a motor to lift and lower the door and with magnetic contact sensors.

So far so easy. The hard part came with the installation, which involved trenching to the hen house for mains power, repairing the damage from this, and troubleshooting a power issue that turned out to be due to a dodgy power adapter. The payoff is that now the chicken coop is also part of the smart home and their owner never has to trudge through a soggy garden again to adjust the programming on a dim LC display with far too few buttons.

2025 Pet Hacks Contest: Fort Bawks Is Guarded By Object Detection

June 9, 2025 by Tyler August 5 Comments

One of the difficult things about raising chickens is that you aren’t the only thing that finds them tasty. Foxes, raccoons, hawks — if it can eat meat, it probably wants a bite of your flock. [donutsorelse] wanted to protect his flock and to be able to know when predators were about without staying up all night next to the hen-house. What to do but outsource the role of Chicken Guardian to a Raspberry pi?

Object detection is done using a YOLOv8 model trained on images of the various predators local to [donutorelse]. The model is running on a Raspberry Pi and getting images from a standard webcam. Since the webcam has no low-light capability, the system also has a motion-activated light that’s arguably goes a long way towards spooking predators away itself. To help with the spooking, a speaker module plays specific sound files for each detected predator — presumably different sounds might work better at scaring off different predators.

If that doesn’t work, the system phones home to activate a siren inside [donutorelse]’s house, using a Blues Wireless Notecarrier F as a cellular USB modem. The siren is just a dumb unit; activation is handled via a TP-Link smart plug that’s hooked into [donutorelse]’s custom smart home setup. Presumably the siren cues [donutorelse] to take action against the predator assault on the chickens.

Weirdly enough, this isn’t the first time we’ve seen an AI-enabled chicken coop, but it is the first one to make into our ongoing challenge, which incidentally wraps up today.
