## 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
