### AI overview

Home Assistant 2026.7 makes purpose-specific automation triggers and conditions the default, aiming to provide more power with less complexity through both the user interface and YAML. The release also rebuilds Activity into a timeline, adds update-all and infrared/radio-frequency panels, improves ZHA Zigbee device management, and introduces 10 community integrations.

### Source excerpt

Tip Don't forget to join our release party live stream on YouTube on July 1, 2026, at 20:00 GMT / 12:00 PT / 21:00 CET! Home Assistant 2026.7! 🎉 This is one of those releases I've been looking forward to for a long time. My favorite by far is what we've done with automations. Purpose-specific triggers and conditions graduate from Labs and become the new default for everyone. 🎉 It comes down to something we've been chasing for years: more power, less complexity. Instead of starting from Home Assistant's internals, which entity, which state, which kind of trigger, you start from what you actually want your home to do. When the bedroom drops below 18°C, turn on the heating. That's it. No technical traps, no quirks to memorize. And because integrations can teach the automation engine their own triggers and conditions, it only gets better from here. All of it right there in our beautiful user interface. The nice thing is, nothing breaks. All your existing automations keep working, worry-free. We've also written tons of great documentation explaining every single trigger, condition, and action, with examples to learn from. And if you're one of those people who prefers writing automations in YAML instead of the UI, you're in for an amazing experience too. User experience is not a synonym for "the UI". YAML users deserve good user experience too. But honestly? I've got a second favorite this release, and that surprised me a little. Activity, what many of you still know as the logbook, has been rebuilt into a slick and clean timeline. 😍 It reads top to bottom like a feed, groups entries by day, and finally speaks the same language as the rest of Home Assistant. I keep opening it just to look at it. And that's just the start. There's a new update-all button, dedicated panels for infrared and radio frequency, an overhauled ZHA Zigbee device management, and 10 new integrations from our community. One more thing before you dive in: the Open Home Foundation is exhibiting at IFA B

Hello everyone, we wanted to do a quick update on what's been happening recently. Life has been pretty busy but there's lots of nice things happening in the background that we'd like to share. PineVoice The PineVoice Home Assistant speaker (formally PineVox) is in its final stages. Production begins. Further on this, there will be limited bundle with this device which will include a PineVoice, Zigbee dongle, power supply and two matter modules. Pair it with a SBC of choice and run your Home Assistant instance locally! PineTime/PineTime Pro The current PineTime LCD is EOL and a new one is replacing it, though it is essentially the same display. These will be shipping in the next PineTime batch. New PineTime Pro samples have been received by developers. Shiny! LoRa? (Left-handed operational Radio authority, obviously) The PineDio USB LoRa Adapter is at the focus of a new effort to begin progress on potential new LoRa devices. MeshCore is the current protocol target for the USB LoRa Adapter along with help from the pyMC_core library project. The current problem with the device is that the crystal oscillator is heating up too much and can cause clock frequency drifting instability. In a nutshell that means your messages come out garbled. This may eventually be fixed with a TXCO (Temperature-Compensated Crystal Oscillator) to maintain a stable clock frequency. Important recent community updates: DanctNIX PineTab2 updates (including factory image) Adam Piggz: PinePhone, PinePhone Pro, PineTab2 all updated to kernel 7.0, and improved USB config.

### AI overview

The article announces that ubisys has joined Works with Home Assistant. It describes ubisys's Zigbee smart home devices for retrofitting, their long hardware and software support, and the company's involvement in developing open standards and improving interoperability with Home Assistant.

### Source excerpt

We're thrilled to welcome ubisys to Works with Home Assistant! This German company has been dedicated to smart home automation for more than 20 years, and offers a range of Zigbee devices designed to help you retrofit your home. If retrofitting is conjuring up images of avocado bathrooms 🥑 and artexed ceilings, fear not - it just means upgrading what you already have, rather than ripping it out and starting again. Better for your home, and the planet 🌍. Here today, here tomorrow Founded in Düsseldorf in 2005, ubisys build devices that last. They back their hardware with a five-year warranty and software updates for the long term, meaning the device you buy today won't end up obsolete in a few years' time - in fact, they're still shipping feature updates for hardware designed in 2010! That kind of longevity aligns closely with the Open Home Foundation's own sustainability principle, and is just one reason why they're such a great (retro)fit for the program! Zigbee is another... Zigbee to the bone If you're scratching your head at the mention of Zigbee, allow me to explain: it's a wireless standard that lets smart home devices communicate with each other, regardless of who made them. Unlike WiFi, it's a mesh network, meaning Zigbee devices "talk" to each other, as well as to a central hub (like your Home Assistant setup), strengthening the connection across your whole home. It runs entirely locally, with no cloud dependency, and is optimized for long battery life. For retrofit devices that need to just get on with their jobs in the background, these qualities really count, and explains why ubisys refer to Zigbee as the backbone of everything they build. And they don't just use the standard, they help shape it: ubisys are active members of the Connectivity Standards Alliance (the organization responsible for maintaining and developing Zigbee), sitting on working groups and committees at the highest level - helping improve the standard for the benefit of the whole communi

### AI overview

This tutorial explains how Matter Bridges allow non-Matter IoT devices, such as Zigbee devices, to operate within a Matter ecosystem. It introduces bridged devices, the Matter data model, and the commissioning workflow for a Matter-Zigbee Bridge.

### Source excerpt

Several big IoT ecosystems have announced integrated support for Matter, e.g., Amazon, Apple, Google and Samsung. It's exciting to expect that more and more devices from multiple brands work natively together, under a bigger Matter ecosystem. Meanwhile, people may have a question: There are many IoT products in the consumers' home already, these can be the devices based on Zigbee, Z-Wave, BLE Mesh and others. Could these non-Matter devices work together with Matter ecosystem? The answer is YES.

### AI overview

A practical guide to using IKEA TRÅDFRI equipment to automate power cycling for a modem or server, including the required hardware, gateway, mobile device, and an alternative MQTT-controlled power socket.

### Source excerpt

Recently I revamped my home internet, and (hopefully) temporarily ended up with a modem that needs to be power cycled from time to time. We're working on getting it fixed, but in the meantime I needed a solution for automated power cycling. There are various ways to turn the power off or on from a Linux computer, and some of these are very karmic. You can get a zigbee USB stick and ditto power plugs, and I am sure this is a lot of fun.
