Heatit Joins Works with Home Assistant — Z-Wave Heating and Safety Devices Get Official Certification
If you’ve been looking for a serious, locally-controlled heating solution for Home Assistant, the Works with Home Assistant program just got a very compelling new member. Heatit — specialists in smart climate and heating control based in Norway — have joined the program, bringing six certified Z-Wave devices into the fold, including what is notably the first Z-Wave smoke detector to receive official certification: the Heatit Z-Smoke 2.
Formerly known as Thermofloor, Heatit has over 30 years of experience building thermostats and controllers designed to handle Scandinavian winters that regularly dip below -20°C. That kind of pedigree means these devices are absolutely built to last — and more than capable of handling whatever your climate throws at them.
What’s Been Certified
Six devices have made it through the Works with Home Assistant testing process:
Heatit Z-Push Wall Controller — a physical wall controller so you’re not always reaching for your phone to adjust things.
Heatit Z-Temp3 — a smart thermostat for precise temperature control.
Heatit Z-TRM6 DC — thermostat controller for DC-powered heating systems.
Heatit Z-Smoke 2 — the first certified Z-Wave smoke detector in the program, and crucially, one that always functions regardless of network status. The smart features are a bonus; the core safety function never depends on connectivity.
Heatit ZM Thermostat 16A — a high-load thermostat suitable for more demanding heating setups.
Heatit Z-HAN2 — for energy monitoring and management.
Together, these cover both sides of a smart heating setup: thermostats handling the actual temperature control, with the wall controller giving you a tactile, always-available way to manage it all without unlocking your phone.
Why Z-Wave Matters Here
All of Heatit’s certified devices connect via Z-Wave, and for heating and safety applications, that’s genuinely the right call. Z-Wave operates on a dedicated frequency — less interference than WiFi, more reliable communication through thick walls and across large homes. It’s also a mesh network, where mains-powered devices help pass signals to one another, which also benefits battery-powered devices by reducing the work they need to do to stay connected.
For something as important as a smoke detector or a heating thermostat, long battery life and reliable range aren’t just nice-to-haves. And because everything runs locally, your heating responds immediately — no routing through a third-party server, no latency waiting on a cloud that might not always be available.
Getting Started
To use these devices, you’ll need a Z-Wave adapter and the Z-Wave integration set up in Home Assistant. The standalone devices support SmartStart, which makes adding them to your Z-Wave network as simple as scanning a QR code — a genuinely painless onboarding experience. For in-wall devices like the thermostats, installation will require a qualified electrician in most regions, so factor that in if you’re planning a full heating setup.
If you want remote access — say, warming the house before you get home — Home Assistant Cloud handles that securely, and your subscription helps fund the Open Home Foundation’s ongoing work, including the Works with Home Assistant program itself.
A Partnership Worth Watching
What’s encouraging about Heatit joining the program isn’t just the hardware — it’s the philosophy behind it. Sustainability and reducing environmental impact are central to how Heatit operates, which maps closely onto the Open Home Foundation’s own principles of privacy, choice, and sustainability. Their CEO, Pål Aksel Forberg, specifically called out the community and the shared focus on open, local-first solutions as the reason this partnership made sense — and that kind of alignment tends to produce better long-term support and more community-responsive product development.
Works with Home Assistant certification isn’t just a badge, either. Every device on that list has been put through rigorous in-house testing by the Home Assistant team to ensure it works seamlessly out of the box. Brands also commit to long-term firmware support and active participation in the community — so you’re not just buying hardware, you’re buying into an ongoing relationship.
For anyone running Home Assistant in a colder climate, or anyone who’s been looking for a serious local-first heating control solution, this is a lineup worth taking a close look at. Time to turn up the heat.
