A Z-Wave home automation network separate from the Wi-Fi, with Home Assistant Green and the official Connect ZWA-2 adapter. In the board a Shelly Wave Pro 3 switches three circuits, a Wave i4 turns push-buttons into scene controls, the Wave H&T reads the climate and the Wave PM Mini the consumption of one circuit. All local, no cloud.
What it does
- Home Assistant Green, with the Connect ZWA-2 adapter, runs the Z-Wave network locally: automations and history stay in the house, with no cloud.
- The Shelly Wave Pro 3 on DIN rail in the board drives three circuits: outside lights, pump, towel rail or other loads within the limits stated by the manufacturer.
- The Wave i4 reads four existing buttons or switches and turns them into scene commands for Home Assistant.
- The battery-powered Wave H&T reads temperature and humidity in the chosen room and makes them available for charts and automations.
- The Wave PM Mini meters the consumption of a circuit or an appliance: the figure lands in Home Assistant's energy dashboard.
- Z-Wave works on a different frequency from Wi-Fi and, in Long Range mode, reaches far corners of the house or the garden.

Before you order
Do you need a hub?
Yes, and it is included: Home Assistant Green is the hub, and the Connect ZWA-2 adapter gives it the Z-Wave radio. Shelly Wave devices do not use Wi-Fi and cannot be controlled without a Z-Wave controller. The Green connects to the router with a network cable.
Why Z-Wave rather than Wi-Fi?
Z-Wave is a network dedicated to home automation, on a different frequency from Wi-Fi: it does not take up Wi-Fi bandwidth and does not depend on the router to control the devices. Mains-powered modules act as repeaters and Long Range mode increases direct range towards distant points, as the manufacturer states.
Does it work with Alexa, Google and Apple?
Yes, by going through Home Assistant. With Apple Home via Home Assistant's HomeKit Bridge integration, free and local. With Alexa and Google Home via Home Assistant Cloud, a subscription service, or by setting it up by hand. Z-Wave devices do not reach voice assistants directly.
Do you need an electrician?
Yes. The modules wire into the 230V line, behind the switches, in the junction boxes or in the board: the connections must be made by qualified personnel, with the installation isolated at the main board. The Wave Pro 3 goes on DIN rail in the consumer unit, the Wave i4 and the PM Mini in the wall boxes.
What happens if there is no internet?
Almost nothing changes: Home Assistant works locally and the Z-Wave network does not use the internet, so automations, control from the home network and the switches all keep working. With the line down you only lose control from outside the house and the voice assistants, which come back with the connection.
Can I add devices?
Yes: Home Assistant handles plenty of Z-Wave devices, including those from other brands, as well as Wi-Fi and, with the right radio, Zigbee and Matter. You can add more Shelly Wave modules for lights, roller shutters and dimmers, Z-Wave opening or flood sensors, and drive them all from the same automations.
Are batteries included?
The Wave H&T takes a CR123A cell, normally supplied in the manufacturer's box: check this on the Amazon listing. The other devices run off the 230V line and Home Assistant Green off its own power supply.
What if a product is out of stock on Amazon?
Get in touch through the contact page quoting the kit code: we will point you to a compatible alternative, with the same protocol and the same functions, so the rest of the kit stays as it is and the installation instructions still hold.
Why buy on Amazon?
Purchase, delivery, returns and warranty are handled by Amazon: delivery times, returns and warranty are shown on Amazon when you buy. The kit is our own work: the products work together and the basket already holds them in the right quantities.
