eufy SoloCam S340

Compiled by SmartHomeWorkflow Research · eufy · Cameras & Doorbells · ~$199.99 (eufy.com US list at time of research (2026-07-19) — never treated as a live price. A $139.99 sale price was showing on the collection page the same day; the list figure is recorded rather than the promotional one. The price is camera-only with the solar panel integrated, and no base station is required.)

Compatibility

EcosystemSupportThe catch
Amazon AlexaWorksWorks with this ecosystemLive streaming to Echo Show devices; eufy lists Alexa as supported.
Google HomeWorksWorks with this ecosystemChromecast and Google Assistant streaming; eufy lists Google Assistant as supported, while noting on the same page that the integration is 'still undergoing development'.
Apple HomeDoesn't workVerified: does not work with this ecosystemeufy states 'HomeKit — Not supported'. Its HomeKit article lists only the eufyCam 2 family and Indoor Cam 2K models on HomeBase 2, and no S-series camera appears; HomeKit Secure Video is confined to that older generation. A January 2026 secondary report of 'expanded HomeKit support' was checked and is NOT corroborated by any eufy primary source.
SmartThingsDoesn't workVerified: does not work with this ecosystemeufy states 'SmartThings — Not supported'. Note the provenance caveat: the vendor support matrix carrying this statement is titled for eufy's doorbell rather than the SoloCam, though it is consistent with the S340 product page, which names only Alexa and Google.
Home AssistantDoesn't workVerified: does not work with this ecosystemeufy states 'Home Assistant — Not supported'. Community projects exist but are unofficial and unsupported by the vendor. Same provenance caveat as SmartThings — the matrix is doorbell-titled.

Protocols: WIFI

Subscription reality

✓ Works without a subscription: Yes.

eufy's own wording is 'Local Storage, No Monthly Fee: One-time purchase. No monthly fee or hidden costs.' A subscription exists but gates ONLY off-site cloud backup — not local recording, live view or AI detection. Cloud is opt-in with a stated free 3-month trial, 'after which continued use will have associated charges'. Plan PRICES are NOT recorded: eufy's own plan page 404s at the obvious URL and only secondary sources carry figures. The existence and optionality of the subscription are primary-sourced; its pricing is not.

Maintenance reality

The catch

The no-subscription claim holds up better here than in most of the category, because the camera genuinely needs no base station and records to 8GB of onboard storage. The trade is closed ecosystems and a trust history: in early 2023 Anker admitted to press that eufy cameras had sent video streams to its web portal without end-to-end encryption, contradicting earlier marketing. Anker states it has since encrypted portal streams, moved to WebRTC, commissioned third-party audits and launched a HackerOne bug bounty — but it does not claim end-to-end encryption across the board today.

Who it's for

Households that want outdoor coverage with no recurring fee and no hub purchase, are content inside Alexa or Google, and have read the encryption history and accepted it.

Late 2022 research had shown event thumbnails uploading to cloud servers with cloud storage disabled, which eufy acknowledged.
