Plugwise is a Dutch maker of smart heating and energy products. Anna is a smart thermostat, Adam is a hub for zone heating with room thermostats and radiator valves, and Smile P1 reads smart meters for electricity and gas. They are set up and controlled from the Plugwise Home app.
Plugwise products talk to a gateway on your home network, and Home Assistant and Homey integrations reach that gateway over the local network. Adam builds a Zigbee network for its thermostats, valves and plugs, and the Home Assistant docs note that Adam also works with Aqara smart plugs. Older Circle and Stealth plugs need a separate Stretch gateway or USB stick.
That suits heating-focused homes that want room-by-room schedules and energy monitoring, and people who plan to bring the system into Home Assistant, Homey or openHAB. It is weaker if you want Matter, direct voice assistant links or Apple Home, none of which we could confirm, and Home Assistant cannot create or edit heating schedules, which stay in the Plugwise app.

The main app. It sets room temperatures, heating schedules and modes, and shows live gas and electricity use. Version 2 added hub setup by scanning the hub label or entering its ID, Wi-Fi setup from the app and guidance when a hub cannot be reached. The App Store listing names Adam HA and Adam SA, Anna and Anna P1, and Smile P1. Published by Anna Technology B.V., with a Plugwise B.V. copyright line. We did not find a Google Play listing, so an Android link is not included.
A Homey app from Plugwise B.V., marked official in Homey's store. It lists Adam, Anna, Floor and Tom, Jip, Lisa, an OpenTherm thermostat, Plug and Smile P1. Every device is listed as needing a Homey Bridge.

Home network (Wi-Fi or LAN)

The gateways are reached over your network by hostname or IP address. The App Store listing describes setting up Wi-Fi from the app, and Home Assistant uses local polling. We could not confirm whether the app works away from home, because the listing does not say.
The Adam gateway runs a Zigbee mesh for its devices, and a Plugwise forum post says that mesh is not connected to Homey. Home Assistant lists the Adam SA as working without a Zigbee stick. The openHAB binding for older products describes a Zigbee USB stick.
Home Assistant has a built-in Plugwise integration that supports Adam, Anna, Smile P1 and the Stretch gateway, and is rated Local Polling. The Home Assistant docs list zone thermostats such as Lisa, valve controllers and smart plugs behind Adam. Plugwise does not maintain it: the volunteers who maintain the code say they are not part of Plugwise as a company. The USB stick is not supported in the core integration.
Plugwise B.V. publishes an app marked official. It works on Homey Cloud, Homey Pro, Homey Pro mini and Homey Self-Hosted Server and requires Homey v12.0.0 or newer. The listing marks every device as needing a Homey Bridge, and lists the technology as LAN.
openHAB's add-on catalog has a PlugwiseHA binding for the Adam gateway with Tom, Floor, Circle and Lisa, and the page says it also covers the Anna thermostat. It does not mention Smile P1. A separate Plugwise binding covers the older USB stick, Circle, Stealth, Scan, Sense and Switch, with only the V2 protocol supported. Plugwise does not maintain either.
The python-plugwise library, released under the MIT licence, talks to Adam, Anna, Smile P1 and other devices and powers the Home Assistant integration. Its maintainers say they are independent of Plugwise. We found no official public API or developer program from Plugwise.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
