What has changed with Withings+?
Withings' developer portal says Withings+ "becomes required on the Start for Free API plan" from 12 October 2026. Withings accounts created after that date need a membership to share health data with an app on the free plan, and that includes apps that are already live. Accounts created before the date are unaffected, and the portal says an Enterprise plan lifts the requirement for specific use cases.
The Home Assistant Withings integration page now carries the same warning, but gives the cutoff as accounts created after 11 October 2026. The one-day difference is probably time-zone wording, but it is a reason to treat the date as approximate rather than exact if you are creating an account close to it.
| Your situation | Does the change affect you? |
|---|---|
| Withings account created before the cutoff, integration already running | No, according to the developer portal |
| New Withings account created after the cutoff | Yes: Withings+ needed to share data with a free-plan app |
| Developer on an Enterprise plan | Not for specific use cases, per Withings |
Why does this matter for Home Assistant users?
It matters if you are about to buy a Withings scale, blood pressure monitor or sleep mat and plan to pull the readings into Home Assistant. The official integration does not talk to your device directly. As the Home Assistant docs describe, you create a free Withings developer account, register an application and paste its client ID and secret into Home Assistant. That developer app is the "free-plan app" the new rule applies to.
The integration is cloud push: Withings sends updates to Home Assistant by webhook, which needs your instance reachable over HTTPS or, for Home Assistant Cloud users, an automatically registered cloudhook. So the data already depends on Withings' servers; the change adds a recurring fee for new accounts on top of the hardware price. If you want data with no cloud account at all, a Bluetooth scale is the alternative, and our best smart scales UK guide compares the local options.

How much does Withings+ cost in the UK?
Withings' support page lists Withings+ at £8.95 a month or £89.50 a year in the UK, roughly £7.46 a month on the annual plan. Trial terms vary by purchase route: buying a qualifying device from the Withings web store includes a month free, while subscribing in the app offers a shorter trial. One Withings bundle page showed £9.95 a month, so confirm the price at checkout.
That is ongoing cost you would not have faced a fortnight ago just to see your weight on a dashboard. Withings+ does include features inside Withings' own app, so some owners will want it anyway, but it is a poor deal if the integration is the only reason.
What should you do now?
If you already run the Withings integration on an older account, there is nothing to do, though it is sensible to avoid deleting and recreating the developer app or the account, because a fresh account would fall under the new rule. If you are buying a new Withings device and already hold an older Withings account, check which account the developer app is tied to before assuming either way; Withings has not published that detail in the pages we reviewed.
Starting from scratch, weigh the Withings+ fee against a local Bluetooth scale. Our Home Assistant 2026.10 round-up covers the rest of this month's release.
What don't we know yet?
Withings has not said whether the existing-account exemption is permanent, whether users on regional Withings sites are treated differently, or what happens to an exempt account if you later delete and recreate its developer app. We have not tested a new-account setup ourselves, so the exact error a new user sees without Withings+ is unverified. Treat any statement beyond the two pages cited here as unconfirmed.
