Our verdict
Withings is the polished, officially supported route into Home Assistant, but it is entirely cloud: no internet means no data. The bigger catch arrived recently: Home Assistant's Withings page now states that accounts created after October 11, 2026 require a Withings+ subscription, so check that before buying a new scale. The docs also say nothing about individual scale models, so confirm Body Smart entities appear (weight readings only show if data was registered in the last 14 days).
What can Home Assistant control on the Withings Body Smart?
| Control | Type | What it does |
|---|---|---|
| Weight | Sensor | Latest weight from the Withings cloud; appears only when data exists from the last 14 days. |
Built-in 'Withings' integration, authorised through Withings OAuth with Application Credentials. It is Cloud Push: Withings calls a webhook on your Home Assistant, so the instance must be reachable on HTTPS port 443 with a certificate from a recognised CA (a self-signed cert will not work), unless you use Home Assistant Cloud, which registers a cloudhook automatically. Measurement sensors such as weight are created dynamically and only exist when Withings has data from the last 14 days. The redirect URL must match the one registered with Withings exactly, including scheme, hostname and port. New Withings accounts created after October 11, 2026 need a Withings+ subscription, per the integration page.

Frequently asked questions
- Does the Withings Body Smart work with Home Assistant locally?
- Partly. The Withings Body Smart connects to Home Assistant through a built-in Home Assistant core integration, which relies on the Withings cloud. It works in Home Assistant, but commands go via the internet and stop working during an outage of your connection or the Withings service.
- Which protocol does the Withings Body Smart use, and do I need a hub?
- The Withings Body Smart uses Wi-Fi. To pair it with Home Assistant you need no hub — it joins your Wi-Fi network directly. Withings's own hub is not required when you integrate through a built-in Home Assistant core integration.
