Solid value at ~£93 with a 2K 180° head-to-toe view, bundled chime and local microSD recording — no subscription required, undercutting Nest's £180+ hardware and competitive with Ring's battery doorbells. The 10,000mAh battery is rated for around 8 months per charge, but topping it back up takes roughly 6 hours with the doorbell off the door entirely — a real hassle if it's your only entry point. The bigger catch for HA users: the local RTSP stream only works when hardwired, so battery-only installs are limited to app-land. Best fit: a budget-conscious wired install where you want local video without paying for cloud storage.

If you can run a cable to the door, this is the most robust local doorbell we've tested: Platinum-certified Works with Home Assistant, RTSP/ONVIF streams that survive a Wi-Fi outage or router reboot, and no subscription. Same 5MP sensor, 180° lens and IP65 shell as the WiFi model, so image quality and night vision are identical — the difference is entirely install and reliability. The WiFi model is a five-minute swap onto existing bell wiring; this one needs a PoE or 12-24V AC run to the door, plus a PoE injector that isn't in the box, so weigh the cable pull and that extra hardware cost against the WiFi variant's lower total price.

The premium local-first option: PoE-powered with dual cameras (5MP front + 8MP package cam), fully local via the excellent native unifiprotect integration, zero subscription. The catch is the ecosystem tax — it doesn't work standalone; it needs a UniFi Protect host, and even the cheapest viable one (a Cloud Gateway Ultra or similar console) adds a meaningful chunk on the doorbell's own £300-447 street price. Genuinely worth it if you already run UniFi gear and want one more device on the same console; a poor first purchase otherwise. Want a reliable local doorbell without buying into a console? The Reolink Video Doorbell PoE gets local RTSP for a fraction of the cost.

The UK's default doorbell at a sharp £79.99 — the right call for most households, but know what you give up against the £219.99 Pro: 2K instead of Retinal 4K, 6x zoom instead of 10x, no radar-based 3D motion or Bird's Eye Zones. The sealed, non-removable battery needs a USB-C top-up every few months; there's no spare pack to swap in. Ding and motion event entities are also currently unreliable in HA on this exact model. Still cloud-only, with a Ring Home subscription needed for recorded clips. If local control matters more than the ecosystem, the Reolink Video Doorbell WiFi is £10 more, fully local, and Works with Home Assistant certified.

The budget pick in TP-Link's pan/tilt indoor line, and where most UK buyers should start: 2K 3MP resolution, 360° pan/114° tilt, and roughly £20-25 versus the £39 C225. What you give up for the discount is the C225's starlight sensor and colour night vision — the C210's infrared night vision is monochrome only, with a 9m/30ft range. It suits a nursery or single-room pet cam well; skip it for a large open-plan space where the C225's AI motion tracking and better low-light picture earn the extra £15. Streams locally over RTSP once enabled in the Tapo app, no subscription required.

At £49.99 the E1 Pro is close to the Tapo C225 while matching its pan/tilt ambition (355° pan / 50° tilt vs the Tapo's 360°/149°) — but the real edge is Reolink's Home Assistant integration, which exposes PTZ, presets and patrol natively with zero HACS add-ons, unlike the Tapo which needs a community plugin just to get pan/tilt working at all. Night vision reaches 12m, plenty for a single room, and it has built-in two-way audio like the Tapo but with a longer IR range (the Tapo tops out at 9m). Best pick for a hallway, nursery or living room where you want real local pan/tilt coverage without a subscription.

At £89.99 this is £30 more than the indoor Pan/Tilt Cam Plus 3K already on this list, and the premium buys what you'd expect for a garden or driveway camera: IP66 weatherproofing rated to -20°C, a wired Ethernet option alongside Wi-Fi, and microSD support up to 512GB against the indoor model's 256GB ceiling. The headline feature, though, is the AI Event Alert system — instead of a bare 'motion detected' push notification like Reolink or Ring give you, it writes a plain-English summary ('a delivery van dropped off a parcel', 'a fox crossed the driveway at 11pm'), which is a genuine step beyond motion-only alerts. The catch: that natural-language layer runs through SwitchBot's cloud and AI Guard Premium subscription (from £3.99/mo) — RTSP streaming into Home Assistant or Frigate for local person detection is free and always available, but the clever sentence-writing isn't. Buy this over the indoor Plus 3K if the camera is actually going outside; buy the Plus 3K if it's watching a hallway and you don't need the weatherproofing.

The cheap way into UniFi Protect: a £75 wire-free 2K camera that runs off its own rechargeable battery and pulls off HA's unifiprotect integration just as well as the £300+ PoE cameras — same local streams, same instant smart-detection events. The real caveat is who this is for: existing UniFi network owners only, since you still need a Dream Machine or Protect console before it records anything. Battery life shrinks fast in busy spots — every motion event wakes it from sleep — and the modest ~6m IR range suits a porch or hallway, not a driveway. Skip it if you're starting from zero.

Ring's mid-tier outdoor pick at £99.99 — a real step up from the plug-in Indoor Cam if you need weatherproofing, but think hard before it over the cheaper battery Stick Up Cam or the pricier Outdoor Cam Plus already covered here: you're paying for Retinal 2K and 6x zoom, not for anything that changes the Home Assistant story, which is still cloud-only with no RTSP path regardless of which Ring outdoor camera you buy. One genuine hardware win over the plug-in Indoor Cam is the built-in siren — HA's ring integration does expose a siren switch for it, 30-second auto-off, something the Indoor Cam simply can't do. Ring sells this as one SKU with a battery-and-mains choice at purchase (mains needs a separate hardwire kit), not two separate listings the way the video doorbells split — so pick your power source once and move on. If local RTSP recording into Frigate matters more to you than Ring's ecosystem and colour night vision, the Reolink Argus 4 Pro is a genuinely local battery/solar alternative for not much more, once you've budgeted for a Reolink Home Hub.

At £122.75 the L2 costs roughly 16% more than the Aqara U200 Lite, and most of that premium buys polish rather than extra hardware — neither lock ships with a keypad or fingerprint reader. Yale's Smart Keypad (~£55) or fingerprint-capable Smart Keypad 2 (~£105+) are separate purchases, same as Aqara's approach. The bigger practical difference is backup access: the L2 has no physical key path by default, so budget for the optional Thumbturn Adapter or a compatible key-and-axle cylinder if you want one. It runs on a rechargeable Yale battery pack (~6 months per charge) rather than swappable AAs, and needs an emergency-function euro cylinder, same requirement as the Aqara.

The mid-tier step below Lock Ultra: SwitchBot's own listing explicitly confirms it fits European cylinders, British oval cylinders and Swiss round cylinders, with eight cylinder adaptors included in the box — no separate adapter purchase like the cheaper original Lock. The base Bluetooth model needs no hub at all for Home Assistant, since the official switchbot integration talks to it directly over local BLE; only Lock Ultra carries the full Works with Home Assistant badge, Lock Pro uses the same core integration but isn't separately certified. It sits meaningfully above the base Lock and below Ultra on price, and adds SwitchBot's own quieter/faster motor generation plus the persistent-calibration behaviour covered below.

Officially Works with Home Assistant certified via Matter over Thread, the Pro (5th gen) uses the same retrofit-over-your-cylinder fitting as the £139 Go, but at £229 it swaps 4 AA batteries for a built-in rechargeable Li-ion pack that charges via USB-C in about 2 hours and lasts roughly 6 months per charge. The extra ~£90 also buys a Wi-Fi radio for Nuki's remote-access feature and, more usefully for HA users, a port for the optional Door Sensor accessory the Go lacks entirely. Worth it for fewer battery swaps and door-open/closed state; skip it if the Go's bare lock entity covers your needs.

A credible euro-cylinder smart lock in the UK at around £236 — it clips over the thumbturn on any euro-profile cylinder with an emergency function, with an adapter for non-standard pins included in the box, so it suits most uPVC and composite doors. Power comes from three replaceable CR123 batteries rated for about six months, rather than the rechargeable pack Nuki's pricier Go offers. The tedee Bridge (~£67/€79, sold separately) unlocks HA's dedicated tedee integration and remote/cloud access, but it isn't your only local-control route: since firmware 2.1 tedee GO also speaks Matter over Thread, so it can join Home Assistant locally through HA's core Matter integration and a third-party Thread Border Router (Apple TV 4K, HomePod mini, etc.) with no tedee Bridge at all, and a community Bluetooth integration offers direct no-Bridge control too. No PIN keypad ships in the box either.

One of the few contact sensors officially certified Works with Home Assistant (Matter over Thread), so pairing and long-term support are as safe as it gets. At £24 it still costs roughly double Aqara's own Zigbee door sensor and over three times IKEA's £7 MYGGBETT, which runs the same Matter-over-Thread stack — pick the P2 for the certification and slimmer 77×22×22mm build, not raw capability. It runs on a single CR123A battery rather than the coin cells most rivals use — bulkier in the frame, but fewer battery changes. You'll still need a Thread border router such as HA's Connect ZBT-1 or an Apple/Google hub.

The one smoke alarm in this group with a real, local Home Assistant route: the core Bosch Smart Home integration talks to the Smart Home Controller over your LAN (local push) and exposes the alarm state, plus an intrusion-alarm switch on the II. It is Zigbee, runs on a replaceable lithium cell (roughly 5 years per retailers, 85dB), and the alarms sound together. The catch is the Bosch controller: you pay for it and you are buying into Bosch's ecosystem, and the detector does not pair with a generic Zigbee dongle. HA can read it and sound or clear the intrusion alarm, but it must never be your only fire warning.

The Zigbee smoke alarm to buy in the UK: Danish-made (Develco), EN 14604 certified, and it works out of the box in Zigbee2MQTT — the 85dB siren doubles as an intruder sounder when triggered from Home Assistant. Unlike interlinked mains alarms, there's no native RF link between units; sounding several together needs a hub automation, not a built-in mesh. At Ø65x40mm on a magnetic ceiling bracket it's compact and tool-free to fit, but the CR123 battery and hub dependency are why it costs more than a basic £10 mains alarm. Treat it as a smart companion to, not a replacement for, your interlinked mains alarms.

The most flexible flood sensor Shelly's made — pick Wi-Fi, Zigbee, Bluetooth or Matter at setup, joining whatever mesh you already run, with a 2m cable extendable to 150m for reaching under a tank or behind an appliance. For most UK Home Assistant users we'd pick Wi-Fi: it's the only mode that gets full local RPC integration via mDNS auto-discovery, no cloud, no extra Zigbee coordinator. Tuck the sensor body out of sight and run the cable to the risk point — under the sink trap, behind the washing machine hose, or along a boiler's pressure-relief pipe. Commit to one radio at pairing; you can't run several at once.
