You need to have a compatible Z-Wave stick or module installed. This needs to be a static controller, which most Z-Wave sticks and modules will be. If yours is a bridge device then it won’t work with OpenZWave, which is what provides Home Assistant’s Z-Wave capabilities. The following devices have been confirmed to work:
- Aeotec Z-Stick Series 5 (see note below)
- Everspring USB stick - Gen 5
- GoControl HUSBZB-1 stick
- Sigma Designs UZB stick
- Silicon Labs SLUSB7000A
- Vision USB stick - Gen5
- Zooz Z-Wave Plus S2 stick ZST10
- ZWave.me Razberry Board
- ZWave.me UZB1 stick
We recommend that you purchase a Z-Wave Plus controller, to take advantage of the improvements this provides. As OpenZWave doesn’t support S2 or Smart Start, there’s no need to buy one just for support of these features.
The alternative to a stick is a hub that supports Z-Wave. Home Assistant supports the following hubs with Z-Wave support:
There are known compatibility issues with older hardware versions of the Aeotec stick not working on the Raspberry Pi 4. Aeotec has released a 2020 hardware revision ZW090-A/B/C Gen5+ with Pi 4 compatibility. Both hardware revisions are still being sold, make informed purchasing decisions if using paired with a Pi 4.
By default this will turn on “disco lights”, which you can turn off by following the instructions in the device specific page
You need to disable the on-board Bluetooth since the board requires the use of the hardware UART (and there’s only one on the Pi3). You do this by following the instructions in the device specific page
