2026 verdict
Setup ease and range put the Nabu Casa Home Assistant Connect ZWA-2 ahead of the Aeotec Z-Stick 7 in this Z-Wave dongle comparison.
It upgrades to the 800 series with much higher transmit power and an external antenna that owners credit with reaching devices through stucco and glass where other coordinators failed, and as official Home Assistant hardware it is effectively plug-and-play. The Aeotec Z-Stick 7 counters mainly on price, being the more affordable of the two, and it remains a stable, long-serving Z-Wave 700 controller for owners who run it for years once its shipping firmware is updated. Both are USB-only, Z-Wave-only radios built for cloud-free Home Assistant, and both migrate an existing network easily. Pick the Nabu Casa Home Assistant Connect ZWA-2 for the newer 800 radio, higher transmit power and antenna range; pick the Aeotec Z-Stick 7 if you want a proven Z-Wave stick for less.

What the differences mean
Radio generation
The Aeotec Z-Stick 7 uses the Z-Wave 700 series. The Nabu Casa Home Assistant Connect ZWA-2 uses the newer Z-Wave 800 series.
Transmit power
The Nabu Casa Home Assistant Connect ZWA-2 transmits at up to +20 dBm against the Aeotec Z-Stick 7's +9.3 dBm, which is the main reason owners report stronger range.
Antenna
The Nabu Casa Home Assistant Connect ZWA-2 has one external antenna. The Aeotec Z-Stick 7 has no external antenna.
Setup and firmware
The Nabu Casa Home Assistant Connect ZWA-2 is official Home Assistant hardware, so HA prompts to install what it needs on insertion. The Aeotec Z-Stick 7 often ships with outdated firmware that has to be updated manually before use.
Which one to buy if
- range through thick walls or across a large home is the priority
Its external antenna and higher transmit power (+20 dBm) are built for exactly that, and owners report it reaching where other coordinators failed.
- budget is the deciding factor and your home is small
The Aeotec Z-Stick 7 is the cheaper of the two and remains stable for modest Z-Wave networks.
- you want the newest Z-Wave radio generation
It runs the 800 series against the Aeotec Z-Stick 7's 700.
- you'd rather skip a firmware update step during setup
As official Home Assistant hardware it installs itself; the Aeotec Z-Stick 7 often ships with outdated firmware to update manually first.

What owners say
Owners of both Z-Wave sticks value running everything locally through Home Assistant with no cloud account, but their day to day experience differs sharply. Aeotec Z-Stick 7 owners report years of dropout-free operation once it is set up, running a dozen or more mixed-brand sensors, locks and openers reliably, though the shipping firmware is the recurring headache: units often arrive outdated, US buyers frequently find it set to the EU frequency, and the update process is technical enough that one owner bricked a stick. Nabu Casa Home Assistant Connect ZWA-2 owners are effusive about range, several say the external antenna and transmit power finally reached exterior switches and sensors through stucco or tempered glass that defeated a Zooz stick or a PoE coordinator, and setup is essentially automatic since Home Assistant prompts to install the driver itself. Their only real complaint is that it costs more than a generic dongle and is Z-Wave only, so Zigbee needs a separate radio.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
